32407959 | This prospective (compassionate), open-label study of remdesivir, which was conducted at Luigi Sacco Hospital, Milan, Italy, between February 23 and March 20, 2020, involved patients with SARS-CoV-2 pneumonia aged ≥18 years undergoing mechanical ventilation or with an oxygen saturation level of ≤94 % in air or a National Early Warning Score 2 of ≥4. |
32408155 | On the intensive care unit, non-invasive ventilation was used to provide oxygen and ventilation support regularly. |
32409443 | The management of patients with COVID-19-induced acute respiratory distress syndrome focuses on identifying the causes for respiratory failure and on following best practices for supportive care with oxygen supplementation and mechanical ventilation. |
32409486 | To assess the effectiveness of hydroxychloroquine in patients admitted to hospital with coronavirus disease 2019 (covid-19) pneumonia who require oxygen. […] Four French tertiary care centres providing care to patients with covid-19 pneumonia between 12 March and 31 March 2020. 181 patients aged 18-80 years with documented severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia who required oxygen but not intensive care. […] Secondary outcomes were overall survival, survival without acute respiratory distress syndrome, weaning from oxygen, and discharge from hospital to home or rehabilitation (all at day 21). […] At day 21, 82% of patients in the treatment group had been weaned from oxygen compared with 76% in the control group (weighted risk ratio 1.1, 95% confidence interval 0.9 to 1.3). […] However, the results of this study do not support its use in patients admitted to hospital with covid-19 who require oxygen. |
32412511 | Although artificial ventilator is one of the last resources for the most severely ill patients, there are patients who are on the verge of not meeting the criteria for intubation; if they are directly intubated, the opportunity for them to overcome the severe phase with high concentration supplemental oxygen would be be missed. |
32412515 | Non-invasive mechanical ventilation and high-flow oxygen therapy are not recommended due to the generation of aerosol (associated with risk of viral spread among health personnel), and neither is extracorporeal membrane oxygenation or the use of steroids. |
32412544 | Benzylidenechromanones, naturally occurring oxygen heterocyclic compounds, having capability to inhibit various protein and receptors, have been designed here to block mutant variety of coronavirus main protease enzyme (SARC-CoV-2 Mpro) isolated from 2019-nCoV with the assistance of molecular docking, bioinformatics and molecular electrostatic potential. (Z)-3-(4’-chlorobenzylidene)-thiochroman-4-one showed highest binding affinity to the protein. |
32423368 | Multivariable logistic regression analysis identified age, sex, respiratory rate, oxygen saturation, history of diabetes, and shortness of breath as factors predictive of intubation. |
32423584 | Eligible patients were adults (aged ≥18 years) admitted to hospital with laboratory-confirmed SARS-CoV-2 infection, with an interval from symptom onset to enrolment of 12 days or less, oxygen saturation of 94% or less on room air or a ratio of arterial oxygen partial pressure to fractional inspired oxygen of 300 mm Hg or less, and radiologically confirmed pneumonia. |
32423911 | On presentation he was hypoxaemic, with an SpO2 of 88% on 15 L/min oxygen, tachycardic and had no audible breath sounds on auscultation of the left hemithorax. |
32425184 | In this setting, myocardial injury is mainly secondary to type 2 myocardial infarction (mismatch in myocardial oxygen supply and demand during respiratory failure); other causes include myocarditis, coronary thrombosis, sepsis or septic shock. |

|
32427774 | This is a case-series of five COVID-19 positive patients who demonstrated severe hypoxemia, declining respiratory performance, and escalating oxygen requirements. […] Patients met the following criteria: COVID-19 positivity, worsening respiratory performance, severe hypoxemia (PaO2<80) despite traditional supportive measures, escalating supplemental oxygen requirements and D-dimer greater than 1.5μg/mL. […] These patients each required significant oxygen supplementation trending toward intubation. […] Administration of thrombolytics was followed by overall improvement in patients’ oxygen requirements, and in three cases, prevented progression to mechanical ventilation, without deleterious effects. |
32428957 | Recovery of the female patient under conventional oxygen therapy. |
32429235 | Emerging evidence suggests that AMPK facilitates central and peripheral reflexes that coordinate breathing and oxygen supply, and contributes to the central regulation of feeding and food choice. […] We propose, therefore, that oxygen supply to the body is aligned with not only the quantity we eat, but also nutrient-based diet selection, and that the cell-specific expression pattern of AMPK subunit isoforms is critical to appropriate system alignment in this respect. […] Currently available information on how oxygen supply may be aligned with feeding and food choice, or vice versa, through our motivation to breathe and select particular nutrients is sparse, fragmented and lacks any integrated understanding. |
32431134 | Remodelled tasks in charge of RPTs were: oxygen therapy daily monitoring, non invasive ventilation (NIV) and continuous positive airways pressure (CPAP) delivery, pronation and postural changes to improve oxygenation, reconditioning with leg/arm cranking and exercises, initial and final patients’ functional assessment by short-physical performance battery (SPPB) and 1-minute sit-to-stand test (1-STS) to evaluate motor conditions and exercise-induced oxygen desaturation. […] Three “what-to-do” algorithms were developed to guide: i) oxygen de-escalation by reducing inhaled fraction of oxygen (FiO2); ii) oxygenation improvement through the use of Venturi mask; iii) reconditioning and physical activity. […] As main topics, RPTs have been involved in oxygen therapy management in almost a third of the admitted patients, reconditioning exercises in 60% of the cases, and initial and final functional motor capacity assessment in all patients. |
32432162 | Although the pathophysiologic mechanisms of STEMI in COVID-19 patients has not been clearly established, we hypothesize that interrelated pathogenetic factors, that we highlight in this report, can play a role in the development of STEMI, including plaque rupture secondary to systemic inflammation, increased pro-coagulants, endothelial dysfunction, impaired fibrinolysis and impaired oxygen utilization leading to demand/supply mismatch and myocardial ischemia. |
32434289 | The patient was transported to operating theatre with supplemental oxygen over a face mask and plastic covering over the trolley. |
32435879 | None required oxygen therapy, and 7 could be managed as outpatients. |
32437770 | Among the 36 patients, 18 had worsening of their clinical status, as defined by severe hypoxia with oxygen therapy requirements greater than 4 Liters/minute and radiological worsening. |
32438425 | One other woman received home oxygen. |
32439306 | In the absence of a vaccine, the management of COVID-19 included antivirals, high-flow oxygen, mechanical ventilation, corticosteroids, hydroxychloroquine, tocilizumab, interferons, intravenous immunoglobulin, and convalescent plasma infusions. |
32442035 | Two systematic reviews suggest a large reduction in mortality with NIV compared with conventional oxygen therapy. |
32442105 | These data indicate that auranofin could be a useful drug to limit SARS-CoV-2 infection and associated lung injury due to its antiviral, anti-inflammatory and anti-reactive oxygen species (ROS) properties. |
32442562 | Fecal samples were collected 2 or 3 times per week from time of hospitalization until discharge; disease was categorized as mild (no radiographic evidence of pneumonia), moderate (pneumonia was present), severe (respiratory rate ≥30/min, or oxygen saturation ≤93% when breathing ambient air), or critical (respiratory failure requiring mechanical ventilation, shock, or organ failure requiring intensive care). |
32443911 | Unfortunately, there is still not a single proven effective drug available, and therefore, current therapeutic guidelines recommend supportive care including oxygen administration and treatment with antibiotics. |
32444366 | Admission oxygen saturation of <88% (3.7, 2.8 to 4.8), troponin level >1 (4.8, 2.1 to 10.9), C reactive protein level >200 (5.1, 2.8 to 9.2), and D-dimer level >2500 (3.9, 2.6 to 6.0) were, however, more strongly associated with critical illness than age or comorbidities. […] Age and comorbidities were found to be strong predictors of hospital admission and to a lesser extent of critical illness and mortality in people with covid-19; however, impairment of oxygen on admission and markers of inflammation were most strongly associated with critical illness and mortality. |
32446312 | There were no significant differences between the two groups in gender, age, underlying diseases, clinical severity, and oxygen-support category at admission. |
32448770 | All patients had elevated IL-6 plasma level (>40 pg/mL) and oxygen saturation <93% in ambient air. […] Clinical outcomes, oxygen support, laboratory data and adverse events were collected over a follow-up of 30 days. […] Forty-five patients (88%) were on high-flow oxygen supplementation, six of whom with invasive ventilation. […] The mortality rate was significantly associated with mechanical ventilation at baseline (83.3% vs 20% of patients on non-invasive oxygen support; p=0.0001). |
32451366 | There will be an estimated 4.6 (3.6-5.5) million COVID-19 hospitalisations, of which 139 521 (81 876-167 044) would be severe cases requiring oxygen, and 89 043 (52 253-106 599) critical cases requiring breathing support. |
32452889 | Despite the same severity of illness and level of hypoxemia at admission, coronavirus disease 2019 patients failed more high flow oxygen via nasal cannula challenges (n = 16, 100% vs n = 5, 45% in controls; p = 0.002), were more often intubated (n = 44, 100% vs n = 22, 56% in controls; p < 0.001) and paralyzed (n = 34, 77% vs n = 3, 14% in controls; p < 0.001), required higher level of positive end-expiratory pressure (15 vs 8 cm H2O in controls; p < 0.001), more prone positioning (n = 33, 75% vs n = 6, 27% in controls; p < 0.001), more dialysis (n = 16, 36% vs n = 3, 8% in controls; p = 0.003), more hemodynamic support by vasopressors (n = 36, 82% vs n = 22, 56% in controls; p = 0.001), and had more often a prolonged weaning from mechanical ventilation (n = 28, 64% vs n = 10, 26% in controls; p < 0.01) resulting in a more frequent resort to tracheostomy (n = 18, 40.9% vs n = 2, 9% in controls; p = 0.01). |
32453889 | A recent theoretical study suggested a direct interaction between COVID-19 viral proteins and haemoglobin (Hb) that could lead to a loss of oxygen carrying capacity. |
32454031 | Of the remaining nine who continued to need respiratory support, seven (77.8%) had iatrogenic preterm deliveries (six by cesarean delivery) for maternal respiratory distress (needing increasing levels of respiratory support without improved oxygen saturation), one had an early term delivery due to PROM, and one, now 30 weeks, has required intensive care with high-flow nasal cannula for three weeks. […] Delivery did not worsen the respiratory status of women with persistent oxygen desaturation and the need for increasing respiratory support. |
32454157 | Viral infections including SARS-CoV are associated with increased levels of reactive oxygen species, disturbances of Ca++ caused by unfolded protein response (UPR) mediated by endoplasmic reticulum (ER) stress and is due to the exploitation of virus’s own protein i.e., viroporins into the host cells. |
32459701 | Of 15 hospitalized women with moderate or severe disease, 10 received respiratory support with supplemental oxygen and one required intubation. |
32459790 | All patients needed oxygen therapy through a nasal cannula; five patients received high-flow nasal cannula therapy, which was later substituted with noninvasive ventilation in four. |
32459919 | We conducted a randomized, open-label, phase 3 trial involving hospitalized patients with confirmed SARS-CoV-2 infection, oxygen saturation of 94% or less while they were breathing ambient air, and radiologic evidence of pneumonia. |
32461141 | COVID-19-associated tissue injury is not primarily mediated by viral infection, but rather is a result of the inflammatory host immune response, which drives hypercytokinemia and aggressive inflammation that affect lung parenchymal cells, diminishing oxygen uptake but also endothelial cells, resulting in endotheliitis and thrombotic events and intravascular coagulation. |
32461911 | We present a case report of a 68-year-old patient with confirmed COVID-19 and a prolonged course of admission, receiving nasal and humidified oxygen, non-invasive and then mechanical ventilation. […] She self-extubated, but remained stable on nasal oxygen only and was transferred for rehabilitation. |
32462858 | The aim of the multicentre study promoted by Nuova FIO is to evaluate the beneficial effects of the systemic Oxygen-Ozone (O2O3) therapy in patients suffering from SARS COV-2 disease in the early phases of the disease, before worsening, up to the need of tracheal intubation. […] The study is based on the rationale on that the systemic oxygen-ozone treatment could be effective, positively influencing the disease evolution and/or being able to mitigate the onset of the cytokine storm syndrome at least partially. |
32463545 | A higher need for assisted ventilation beyond pure oxygen support (Invasive Mechanical Ventilation or Non-Invasive Ventilation) and a higher admission to intensive or semi-intensive care units was observed in patients with overweight and obesity (p<0.01 and p < 0.05, respectively) even after adjusting for sex, age and comorbidities (p<0.05 and p<0.001, respectively), or when patients with dementia or advanced cancer were removed from the analysis (p<0.05). |
32469614 | All five patients were hospitalized, two required supplemental oxygen, and none required mechanical ventilation. |
32470186 | Severe case was confirmed when one of the following criteria occurred: 1) dyspnea, respiratory rate ≥30 breaths/min, 2) blood oxygen saturation ≤93%, and 3) PaO2 /FiO2 ≤300 mmHg. |
32471203 | As SARS-CoV-2 can be transmitted through droplets and aerosols, we cannot ignore the risk of transmission during hyperbaric oxygen therapy (HBOT). […] Our hyperbaric oxygen therapy center prioritizes preventing the spread of COVID-19 and maintaining operation for the patients during the pandemic. […] The aim of this article is to share the protocol that we have adopted in our hyperbaric oxygen therapy center to help prevent the spread of COVID-19. |
32471650 | Clinical presentation of pulmonary embolism patients was usually characterized by persistence or worsening of respiratory symptoms, with increasing oxygen requirement. |
32471783 | We present a case of a 72-year-old male with COVID-19 syndrome who presented to the emergency department with minimal symptoms but low peripheral oxygen saturation readings. […] This case highlights the utility of peripheral oxygen measurements in the evaluation of patients with SARS-CoV-2 infection. |
32471930 | The role of percentage saturation of hemoglobin with oxygen (oxygen saturation), blood pressure and early use of point-of-care ultrasound in differential diagnosis and specific management is detailed. |
32472676 | In multivariable logistic regression analysis, risk factors for severe infection included pre-existing renal disease (odds ratio [OR], 7.4; 95% CI 2.5-22.0), oxygen requirement at hospitalization (OR, 2.9; 95% CI, 1.3-6.7), acute renal injury (OR, 2.7; 95% CI 1.3-5.6) and initial CRP (OR,1.006; 95% CI, 1.001-1.01). […] Acute or pre-existing renal disease, supplemental oxygen at the time of hospitalization and initial CRP were independent predictors for the development of severe COVID-19 infections. |
32470515 | Admission and oxygen supply was required in 4.9% (2 patients in the Ramipril and 3 in control), and 4 of them died (two in each randomized group). |
32470602 | We report three cases of COVID-19 pneumonia who progressed while using antiviral drugs and needed supplementary oxygen therapy, improved after treatment with nafamostat. […] These preliminary findings show the possibility that Nafamostat can be considered to be used in elderly patients with COVID-19 pneumonia who need oxygen therapy. |
32473964 | While the best option in terms of non-invasive systems of oxygen delivery is still a matter of debate, it also remains unclear as to whether or not the optimal in-bed positioning of patients might also help to improve their oxygen saturation levels. […] On the basis of three representative cases, it is possible to propose the following hypotheses: (i) how patients are positioned has a strong influence on their oxygen saturation levels; (ii) saturation-optimalised positions are patient-specific; (iii) prone positions require ergonomic devices; and (iv) saturation-optimalised positions should aim to place the most affected part(s) of the lung(s) on top. |
32475761 | If dexmedetomidine can improve compliance with non-invasive oxygen support (the current recommended first-line therapy) while promoting better oxygenation, it may also decrease the need for mechanical ventilation and thus improve mortality. |
32476080 | The following variables were extracted for this study: age, gender, temperature, and saturation of oxygen on admission, treatment with heparin, hydroxychloroquine, azithromycin, steroids, tocilizumab, a combination of lopinavir with ritonavir, and oseltamivir, together with data on mortality. […] This association remained significant when saturation of oxygen < 90%, and temperature > 37 °C were added to de model with OR 0.54 (0.36-0.82) p = 0.003, and also when all the other drugs were included as covariates OR 0.42 (0.26-0.66) p < 0.001. |
32479771 | A risk score was developed incorporating twelve characteristics: age>40, male, non-white ethnicity, oxygen saturations<93%, radiological severity score>3, neutrophil count>8.0 x109/L, CRP>40 mg/L, albumin<34 g/L, creatinine>100 µmol/L, diabetes mellitus, hypertension and chronic lung disease. |
32481322 | Frequency of requiring supplemental oxygen or non-invasive ventilation; 5. |
32481340 | All patients had oxygen treatment with HFNC, as well as regular treatment of antivirals and traditional Chinese medicine. […] HFNC treatment has its advantages in providing oxygen therapy in COVID-19, but healthcare professionals should still pay close attention to changes in patients’ oxygenation rates and respiratory frequency. |
32481381 | After the operation, we routinely give symptomatic treatments such as anti-infection, nebulization and oxygen inhalation. |
32482597 | At baseline, all patients were on high-flow supplemental oxygen and most (78% of TCZ patients and 61% of standard treatment patients) were on non-invasive ventilation. |
32484930 | While arterial oxygen saturations (87.58±3.12%) dropped in room air in the pre-tocilizumab period, post-tocilizumab they normalized in all patients (94.42±1%). |
32489666 | A 55-year-old male COVID-19-positive patient with obstructive sleep apnoea (OSA), diabetes, and obesity presented with cough and shortness of breath, escalating to requiring high-flow oxygen therapy by high-velocity nasal insufflation. […] The patient’s flow rate and oxygen fraction remained labile throughout much of the hospitalization. […] The patient was alert and oriented and was instructed on the operation of the high-flow system, specifically the adjustment of both flow rate and oxygen percentage. […] The patient was instructed to modify oxygen to maintain an SpO2 (peripheral capillary oxygen saturation) target range, and flow rate to address dyspnoea as well as reduction of flow as tolerated when other staff entered the room. |
32492530 | Severe pneumonia was defined as an oxygen saturation ≤ 93% at room air. |
32493441 | Only adult (≥18y old) patients will be recruited with recent (≤16 days) COVID-19 infection and acute hypoxia (defined as PaO2/FiO2 below 350mmHg or PaO2/FiO2 below 280 on supplemental oxygen and immediately requiring high flow oxygen device or mechanical ventilation) and signs of systemic cytokine release syndrome characterized by high serum ferritin, or high D-dimers, or high LDH or deep lymphopenia or a combination of those, who have not been on mechanical ventilation for more than 24 hours before randomisation. […] This ordinal scale is composed of (1) Death; (2) Hospitalized, on invasive mechanical ventilation or ECMO; (3) Hospitalized, on non-invasive ventilation or high flow oxygen devices; (4) Hospitalized, requiring supplemental oxygen; (5) Hospitalized, not requiring supplemental oxygen; (6) Not hospitalized. |
32493468 | Patients will be randomly assigned to the intervention groups or the control group with the following eligibility criteria: ≥ 18 years of age AND (oxygen saturation (SPO2) ≤ 93% OR respiratory rate ≥ 24) AND at least one of the following: Contactless infrared forehead thermometer temperature of ≥37.8, cough, sputum production, nasal discharge, myalgia, headache or fatigue on admission, and time of onset of the symptoms should be acute (Days ≤ 14). |
32495226 | In the absence of a vaccine and specifically designed antivirals, the medical community has proposed the use of various previously available medications in order to reduce the number of patients requiring prolonged hospitalizations, oxygen therapy, and mechanical ventilation and to decrease mortality from coronavirus disease 2019 (COVID-19). |
32498065 | All 3 had ill contacts in the home or had been to the pediatrician and presented with mild to moderate symptoms including fever, rhinorrhea, and hypoxia, requiring supplemental oxygen during their hospital stay. |
32499303 | Data on demographics, COVID-19 diagnosis, famotidine use, drug-related side effects, temperature measurements, oxygen saturations and symptom scores were obtained using questionnaires and telephone interviews. […] The combined symptom score improved significantly within 24 hours of starting famotidine and peripheral oxygen saturation (n=2) and device recorded activity (n=1) increased. |
32500773 | On computed tomography scans, she had extensive interstitial lung fibrosis in addition to a positive COVID-19 polymerase chain reaction test requiring 6 L of oxygen via nasal cannula on admission. […] After administration of methylprednisolone, the patient improved and was weaned off her oxygen requirements and was discharged home. |
32503620 | Secondary: 14 days after treatment - C-Reactive Protein test x Neutrophil to Lymphocyte Ratio , Interleukin-6, malondialdehyde (MDA) levels reduction - Percentage of patients who require supplemental Oxygen - Mean hospital stay length RANDOMISATION: Patients will be allocated to each group (ratio 1:1) by using an online randomization tool: http://www.graphpad.com/quickcalcs/index.cfm BLINDING (MASKING): This will be a double-blind study in which participants and those assessing the final outcomes will be blinded to group assignment. |
32503657 | Routine treatment for patients with the corona virus will be administered, this includes oxygen therapy, drugs that reduced phlegm and relieve cough, including thymosin, proprietary Chinese medicine, etc. |
32503662 | Secondary endpoints include change in NEWS2 at 96 hours after randomisation, admission to intensive care unit, mortality (in-hospital, and at 30 and 90 days), duration of hospital admission, clinical status on a 7-point ordinal scale 14 days after randomization ([1] Death [2] Hospitalised, on invasive mechanical ventilation or extracorporeal membrane oxygenation [3] Hospitalised, on non-invasive ventilation or high flow oxygen devices [4] Hospitalized, requiring supplemental oxygen [5] Hospitalised, not requiring supplemental oxygen [6] Not hospitalized, but unable to resume normal activities [7] Not hospitalised, with resumption of normal activities), and improvement in protein biomarker profiles (C-reactive protein, markers of renal and hepatic injury, and established cardiac biomarkers like cardiac troponin and B-type natriuretic peptide) at 96 hours after randomization. |
32503663 | Patients aged 18-80 years admitted to specialized COVID-19 wards in 5 Belgian hospitals with recent (< 2 weeks prior to randomization) confirmed COVID-19 infection and acute respiratory failure defined as a PaO2/FiO2 below 350 mmHg or SpO2 below 93% on minimal 2 L/min supplemental oxygen. […] The primary endpoint of this intervention is measuring oxygenation after 5 days of inhaled (and intravenous) treatment through assessment of a change in pretreatment and post-treatment ratio of PaO2/FiO2 and through measurement of the P(A-a)O2 gradient (PAO2= Partial alveolar pressure of oxygen, PaO2=Partial arterial pressure of oxygen; FiO2= Fraction of inspired oxygen). |
32503877 | Acalabrutinib, a selective BTK inhibitor, was administered off-label to 19 patients hospitalized with severe COVID-19 (11 on supplemental oxygen; 8 on mechanical ventilation), 18 of whom had increasing oxygen requirements at baseline. […] At the end of acalabrutinib treatment, 8/11 (72.7%) patients in the supplemental oxygen cohort had been discharged on room air, and 4/8 (50%) patients in the mechanical ventilation cohort had been successfully extubated, with 2/8 (25%) discharged on room air. |
32505805 | The primary outcome measures were COVID-19 requiring oxygen (oxygen therapy or noninvasive ventilation) and critical COVID-19 (requiring invasive mechanical ventilation or extracorporeal membrane oxygenation, ECMO). […] By April 14, among the 617 pregnant women with COVID-19, 93 women (15.1 %; 95 %CI 12.3-18.1) had required oxygen therapy and 35 others (5.7 %; 95 %CI 4.0-7.8) had had a critical form of COVID-19. […] Among the women who gave birth, rates of preterm birth in women with non-severe, oxygen-requiring, and critical COVID-19 were 13/123 (10.6 %), 14/29 (48.3 %), and 23/29 (79.3 %) before 37 weeks and 3/123 (2.4 %), 4/29 (13.8 %), and 14/29 (48.3 %) before 32 weeks, respectively. |
32506055 | Close monitoring for temperature and oxygen saturation during hemodialysis sessions may be reasonable. |
32507619 | Most participants referred absence of training on the use of personal protective equipment, oxygen ventilation systems and COVID-19 therapies. |
32508022 | Although no effective treatment is formally approved for COVID-19 infection, support of ventilation with oxygen therapy and sometimes mechanical ventilation is often required. |
32509258 | We speculated that in COVID-19, beyond the classical pulmonary immune-inflammation view, the occurrence of an oxygen-deprived blood disease, with iron metabolism dysregulation, should be taken in consideration. |
32510978 | While the majority of patients mount an appropriate antiviral response and recover at home, others progress to respiratory distress requiring hospital admission for supplemental oxygen. |
32511678 | There was no statistical difference between ACEIs and ARBs groups in terms of hospital admission rate, oxygen therapy and need for non-invasive ventilation. |
32512089 | Currently, approved treatment modalities consist of only supportive care and oxygen supplementation. |
32512491 | This little-known information should be deemed as crucial as the SARS-CoV-2 relationships with oxygen saturation and the Renine Angiotensin System but it currently remains unexploited. […] We theorized that the Angiotensin II clearance by the red blood cells could trigger the release of its oxygen content in the bloodstream. |
32512988 | We hereby report a case of a 44-year-old COVID-19 positive male patient suffering from hypoxic respiratory failure that was successfully treated with high flow nasal cannula oxygen therapy in a negative pressure intensive care room. |
32513308 | Eligible participants include adults (≥ 18 years) with evidence of SARS-CoV-2 infection by PCR test of nasopharyngeal or oropharyngeal swab within 14 days of randomization, evidence of infiltrates on chest radiography, peripheral capillary oxygen saturation (SpO2) ≤ 94% on room air, and/or need for supplemental oxygen, non-invasive mechanical ventilation, or invasive mechanical ventilation, who are willing and able to provide written informed consent prior to performing study procedures or who have a legally authorized representative available to do so. […] Hospitalized, not requiring supplemental oxygen 4. […] Hospitalized, requiring supplemental oxygen 5. […] Hospitalized, requiring high-flow oxygen therapy or non-invasive mechanical ventilation 6. |
32513515 | These measures include the addition of long-acting inhaler therapies, pulmonary rehabilitation, oral therapies, oxygen and lung transplantation. |
32513808 | Approaches to procedural sedation can be modified to reduce the risk of droplet or aerosol transmission by decreasing nasal cannula oxygen supplementation flows. […] Decreasing the need for oxygen supplement can be accomplished by opioid and sedative sparing strategies, including the use of multimodal analgesia and non-pharmacologic analgesic and anxiolytic interventions. |
32515699 | Thus, hemoglobin loses the capability for transporting oxygen, which aggravates hypoxia and worsens the prognosis. |
32516107 | Dyspnea was the patient’s main complaint at the time of admission in this center and the oxygen saturation was 84%. […] The patient’s felt relieved immediately after the procedure; however, the oxygen saturation did not raise above 85% despite the oxygen therapy. |
32516861 | Severe COVID-19, as expressed by elevated lactate dehydrogenase and low oxygen saturation at emergency department admission, is associated with a rapid progression to death in these patients. |
32519786 | Our patients were treated by oxygen via face mask in one case and mechanical ventilation as supportive treatment in the other patient. |
32519842 | First, nanoparticles (NPs) can offer alternative methods to classical disinfection protocols used in healthcare settings, thanks to their intrinsic antipathogenic properties and/or their ability to inactivate viruses, bacteria, fungi, or yeasts either photothermally or via photocatalysis-induced reactive oxygen species (ROS) generation. |
32519944 | A comparative presentation of the clinical features of the first 50 COVID-19 patients with and without acute respiratory distress syndrome (ARDS) who were hospitalized in the University Hospital Aachen. 24 intubated patients were treated in the intensive care unit for ARDS of varying degrees of severity, while 26 patients who were breathing spontaneously without ARDS, but nevertheless needed supplemental oxygen, were treated in a separate isolation ward. […] Patients without ARDS had persistently elevated inflammatory parameters and fever for at least one week, with an accompanying need for supplemental oxygen. […] COVID-19 patients without ARDS may likewise require prolonged hospitalization because of persistently elevated inflammatory values with a simultaneous need for supplemental oxygen. |
32521167 | Recognition of these issues and careful counseling of patients about the proper means for measuring their oxygen saturation and when to seek assistance can help ensure successful implementation of needed monitoring programs. |
32522574 | This article compares the symptoms of acute mountain sickness (AMS) with those of SARS-CoV-2 infection and explores overlapping patho-physiological mechanisms of the respiratory system including impaired oxygen transport, pulmonary gas exchange and brainstem circuits controlling respiration. […] In this context, we also discuss the potential impact of SARS-CoV-2 infection on oxygen sensing in the carotid body. |
32523928 | The diagnosis of pulmonary embolism is challenging in symptomatic COVID-19 patients since shortness of breath, chest pain, tachycardia, tachypnoea, fever, oxygen desaturation and high D-dimer blood levels might be features of both diseases. |

32539537 | Patients with COVID-19 are described as exhibiting oxygen levels incompatible with life without dyspnea. […] It is possible that coronavirus has an idiosyncratic action on receptors involved in chemosensitivity to oxygen, but well-established pathophysiological mechanisms can account for most, if not all, cases of silent hypoxemia. […] These mechanisms include how dyspnea and the respiratory centers respond to low levels of oxygen, how prevailing carbon dioxide tensions (PaCO2) blunt the brain’s response to hypoxia, effects of disease and age on control of breathing, inaccuracy of pulse oximetry at low oxygen saturations, and temperature-induced shifts in the oxygen dissociation curve. |

32549692 | Five out of the 10 patients - including the patients who presented with hypoxia - subsequently required supplemental oxygen postoperatively. […] Two patients had persistently elevated oxygen demands requiring prolonged administration of supplemental oxygen therapy beyond postoperative day 3. […] Our findings suggest that hip fracture patients who present with asymptomatic or mild COVID-19 infection may have temporarily increased oxygen demands postoperatively, but they can safely undergo early surgical intervention after appropriate medical optimization. |
32550056 | Supportive treatment such as oxygen therapy, extracorporeal membrane oxygenation, and ventilator support can also be used. |
32553536 | Survival and mechanical ventilation (MV) outcomes were reported for 14 days and stratified by disease severity designated at admission (severe, ≥3L supplemental oxygen to maintain oxygen saturation >93%). |
32553908 | Oxygen support was required for 24.1% (13/54), including high flow oxygen (n=2), noninvasive (n=1) and invasive (n=3) mechanical ventilation, and extracorporeal membrane oxygenation (n=1). |

32563601 | Testing positive for SARS-CoV-2 and lower oxygen saturations were associated with need for ICU and invasive mechanical ventilation, and with death. […] For every 100 admitted persons under investigation, 9 will require ICU stay, invasive mechanical ventilation, or both on arrival and another 12 within 2 to 3 days of hospital admission, especially persons under investigation with lower oxygen saturations and positive SARS-CoV-2 swab results. |
32564028 | The assessment of the extent of ARF should be based on arterial or capillary blood gas analysis under room air conditions, and it needs to include the calculation of oxygen supply (measured from the variables of oxygen saturation, hemoglobin level, the corrected values of Hüfner’s factor, and cardiac output). […] A significant proportion of patients with ARF present with relevant hypoxemia, which often cannot be fully corrected, even with a high inspired oxygen fraction (FiO2) under NHF. […] In this situation, the oxygen therapy can be escalated to CPAP or NIV when the criteria for endotracheal intubation are not met. |
32565097 | More SARS patients required oxygen supplementation than COVID-19 patients (18.6 vs. |
32565364 | Similarly, the role of oxygen therapy as an anti-inflammatory strategy is evident and access to oxygen therapy should be prioritized to avoid the aggravation of COVID-19 infection. |

32574432 | Recently the internet has been abuzz with new ideas to treat COVID-19, including hyperbaric oxygen (HBO2) therapy, undoubtedly driven by the fact that until recently there have been few therapeutic options for this highly contagious and often lethal infection. . . . […] Refractory hypoxemia is certainly treatable with hyperbaric oxygen due to the obvious effect of increasing inspired oxygen partial pressure (PO2), the major reason for using HBO2 for its established indications. […] However, the length of time during which patients can safely be administered HBO2 inside a chamber is limited, due to practical issues of confinement and isolation from other necessary medical interventions, but also because of oxygen toxicity. |

[…] Punctual and early use of HP and CRRT in the treatment of ARDS in patients with COVID-19 prevented the progression of ARDS and patient intubation, reduced respiratory distress and the patient’s dependence on oxygen, prevented other complications such as AKI and septic shock in the patient, and reduced mortality and hospital length of stay. |
32596244 | Therefore, in this review, we summarize the mounting evidence obtained from preclinical studies using animal models of lethal pneumonia where curcumin exerts protective effects by regulating the expression of both pro- and anti-inflammatory factors such as IL-6, IL-8, IL-10, and COX-2, promoting the apoptosis of PMN cells, and scavenging the reactive oxygen species (ROS), which exacerbates the inflammatory response. |
32596641 | Ten cases (38.5%) demonstrated moderate to severe sleep apnoea-hypopnea syndrome (SAHS) when using an oxygen desaturation index ≥15 times/hour as the cut-off value. |
32597503 | However, sustaining redox homeostasis and reactive oxygen species (ROS) generation in neutrophils are critical during chemotaxis, oxidative burst, phagocytosis, and neutrophil extracellular trap (NET) formation. |

32603901 | We found no significant difference between patients with and without asthma in terms of severity (length of stay, maximal oxygen flow needed, noninvasive ventilation requirement, and intensive care unit transfer); 52.2% of the patients with asthma had Global INitiative for Asthma step 1 asthma. |
32604593 | The aim of our study is to propose a remote patient monitoring solution through a smart phone application (Smart Patient) collecting health data to support diagnosis, monitoring and predicting poor outcome in asymptomatic/mild cases of COVID-19, including signs and symptoms, risk factors, comorbidities, medications and vital signs such as body temperature, respiratory rate, heart rate and oxygen saturation. |
32605182 | We studied the potential mechanisms of e-cig vape cartridge aerosol induced inflammatory response by evaluating the generation of reactive oxygen species by MCT, VEA, and cartridges and their effects on the inflammatory state of pulmonary epithelium and immune cells both in vitro and in vivo. […] Cells exposed to these aerosols generated reactive oxygen species, caused cytotoxicity, induced epithelial barrier dysfunction, and elicited an inflammatory response. |

32609464 | At baseline, muscle function was consistent with intensive care unit-acquired weakness and the patient still needed mechanical ventilation (MV) and oxygen support. |
32610262 | RECOVERY trial is the only randomized controlled trial that has shown a significant reduction of death by 35% in ventilated patients and by 20% amongst patients on supplemental oxygen therapy with the dexamethasone, although no benefit was observed in mild cases. |
32610859 | All 4 patients in the severe category had raised FDP, D-Dimer levels and they needed oxygen support. […] Patients with older age and associated comorbid conditions (COPD and diabetes) seem to have greater risk for lung injury thereby requiring oxygen support during the course of disease and these patients also had greater derangement in their biochemical profile. |
32612430 | Safety issues related to infection spread limit the use of high flow nasal oxygen (HFNO) and continuous positive airway pressure (CPAP) in hypoxic patients. |
32615317 | Meanwhile, we revealed that metabolic, glucocorticoid, and reactive oxygen species-associated networks were enriched in both short- and long-term infection models. |
32616134 | Methods Totally 63 discharged patients in Wuhan,China,who underwent both chest CT and reverse transcription-polymerase chain reaction(RT-PCR)from February 1 to February 29,2020,were included.With RT-PCR as a gold standard,the performance of chest CT in diagnosing COVID-19 was assessed.Patients were divided into mild/moderate and severe/critical groups according to the disease conditions,and clinical features such as sex,age,symptoms,hospital stay,comorbidities,and oxygen therapy were collected.CT images in the recovery phase were reviewed in terms of time from onset,CT features,location of lesions,lobe score,and total CT score. […] 53.85%; χ2=18.90, P<0.001), lower nasal oxygen therapy ratio (81.08% vs. |
32617244 | This case highlights the risk of delayed thromboembolic complications in patients with COVID-19 infection and the need to identify the subgroup of patients with a higher risk of thromboembolism, such as discharges to nursing homes and those in need of oxygen requirement; and those with underlying comorbid conditions that may require anticoagulation for a longer duration. |
32617738 | Patients with ODs less frequently needed oxygen therapy. |
32618262 | The CXR score showed a significant positive correlation with C-reactive protein, lactate dehydrogenase, and fever duration, and a negative correlation with oxygen saturation. |
32618463 | In the emergency department, it is included the management of suspicious cases and, if it any risk factor is found, complementary tests are carried out for precise diagnosis and admission assessment; In case of oxygen saturation <95% and poor general condition, valuation is requested for admission to the ICU. |
32618497 | Multivariate analysis showed that oxygen requirement and fever during admission were the only clinical factors independently associated with higher NAb titers. |
32618794 | On hospital day 3, owing to increased dyspnea and oxygen requirement, the patient was treated with tocilizumab followed by 5 days of remdesivir. |
32619764 | Among the five patients treated, two needed mechanical ventilation and one needed high-flow cannula oxygen. |
32620311 | Every patient sent a daily clinical questionnaire with temperature and oxygen saturation 3 times a day. |
32622450 | Medical management is mostly supportive with antipyretics, hydration, oxygen supplementation, and other measures as dictated by clinical need. |

32633712 | All women requiring oxygen >5 L/min were intubated. |
32633856 | Symptoms such as fever or cough, and signs such as oxygen saturation or lung auscultation findings, are the first and most readily available diagnostic information. |
32634734 | Unlike patients with other forms of Acute Respiratory Distress Syndrome, these patients do not exhibit increased lung stiffness or dramatic dyspnea., even in the presence of arterial blood oxygen levels lower than that seen normally in mixed venous blood. […] Urgent intubation and mechanical ventilation with high inflation pressures and raised inhaled oxygen concentration have proved unhelpful or worse, but why? […] Search for an open PFO after a large drop in arterial oxygen saturation can be performed at the bedside with a variety of well-established techniques including bedside echocardiography, nitrogen washout test, and imaging studies. |
32635353 | We present the case of a 48-year-old male with severe COVID-19, on the verge of meeting intubation requirements, who needed progressive oxygen support for respiratory distress. |
32637278 | Poor clinical outcomes of critically ill patients are most likely due to the impaired gaseous exchange in the lungs in addition to the decreased oxygen-carrying capacity caused by the destruction of red blood cells. |
32639236 | Patients were matched on positive end-expiratory pressure, fractional inspired oxygen tension, and respiratory rate. |
32639466 | Critical illness was associated with older age (p = 0.017), longer duration of symptoms (p = 0.036), and lower oxygen saturation on presentation (p = 0.016); with more thrombocytopenia (p = 0.015); higher C-reactive protein (p = 0.031); and lower WBC count (p = 0.039). |

32653511 | In contrast, some studies have reported that EPA and DHA can make cell membranes more susceptible to non-enzymatic oxidation mediated by reactive oxygen species, leading to the formation of potentially toxic oxidation products and increasing the oxidative stress. |
32654557 | When comparing exposure to RAAS inhibitors and nonexposure to RAAS inhibitors for intensive care unit admission, high-flow oxygen therapy, and death, the adjusted odds ratios (95% CIs) were 1.515 (0.402-5.701), 0.663 (0.272-1.619), and 1.363 (0.513-3.662), respectively. |
32654656 | Methodology: Although the dominant approach for these asymptomatic/paucisymptomatic patients is to monitor oxygen saturation, we suggest additionally considering the potential merits and utility of home-based imaging. |
32654921 | Automatic recording was made of demographic variables, severity parameters, laboratory data, assisted ventilation (HFO: high-flow oxygen therapy and IMV: invasive mechanical ventilation), oxygenation (PaO2, PaO2/FiO2) and complications. […] High-flow oxygen therapy was used in 62.7% of the patients, with failure in 85%. |
32654963 | Compared with patients in the highest RVLS tertile, those in the lowest tertile were more likely to have higher heart rate; elevated levels of D-dimer and C-reactive protein; more high-flow oxygen and invasive mechanical ventilation therapy; higher incidence of acute heart injury, acute respiratory distress syndrome, and deep vein thrombosis; and higher mortality. |
32658884 | Sixty-five patients adhere the televideoconsultation completely and were cured, also with home oxygen therapy and other treatments additional to the standard anti-inflammatory and antibiotic drugs. |
32660611 | Secondary Objectives • Number of days free of mechanical ventilation at Day 29 • Duration of intensive care unit stay at Day 29 • Change from baseline in Sequential Organ Failure Assessment (SOFA) score at Day 29 • Change from baseline in peripheral capillary oxygen saturation/ fraction of inspired oxygen (SpO2 /FiO2) at Day 29 • Duration of hospitalization at Day 29 • Survival (based on all-cause mortality) at Day 60 and Day 90 Safety • Incidence of treatment-emergent adverse events and treatment-emergent serious adverse events. |
32661507 | In addition to routine care and measures-such as oxygen therapy, antiviral therapy, and respiratory support-treatment of underlying disease, nutritional support, sputum expectoration complication prevention, and psychological support should also be considered for elderly patients. |
32666316 | Oxygen saturation level, CRP, LDH, and blood cell counts were collected and compared between CT/RT-PCR classes. |
32667150 | Outcome measures evaluated at the admission in Rehabilitation Unit were: type of respiratory supports needed, fraction of inspired oxygen (FIO2), partial pressure of oxygen (PaO2), FIO2/PaO2, Barthel Index (BI), modified Medical Research Council (mMRC) Dyspnoea Scale, and 6-Minute Walking Test (6-MWT). |

32670524 | Six patients had pneumonia, and 4 needed oxygen therapy. […] A rapid clinical improvement of tachypnea/dyspnea and oxygen saturation was observed, after red blood cell exchange transfusion, in a young girl with SCD and worsening of anemia (Hb level from 9.2 g/dl to 6.1g/dl). |
32671348 | To design and test a ventilator circuit that can be used for ventilation of two or more patients with a single ventilator, while allowing individualization of tidal volume, fractional concentration of oxygen, and positive end-expiratory pressure to each patient, irrespective of the other patient’s respiratory system mechanics. |
32672430 | For each patient, as gas exchange index through the alveolocapillary membrane, we determined the alveolar-arterial oxygen gradient (AaDO2) and the alveolar-arterial oxygen gradient augmentation (AaDO2 augmentation). […] For each patient, as measurement of hypoxemia, we determined oxygen saturation (SpO2), partial pressure of oxygen in arterial blood (PaO2), PaO2 deficit and the ratio between arterial partial pressure of oxygen by blood gas analysis and fraction of inspired oxygen (P/F). […] Patients of ICU Group had lower oxygen saturation, PaO2, P/F and higher heart rate, respiratory rate, AaDO2, AaDO2 augmentation and lactate than patients of Non-ICU Group. |
32672840 | During a median follow-up of 20 days, 30 (13.8%) patients were admitted to the intensive care unit (ICU) for high-flow nasal cannula or higher-level oxygen support measures to correct hypoxemia. |
32672860 | Lymphocyte count and pulse oximetry oxygen saturation/FiO2 ratio increased by days 3 and 5, whereas C-reactive protein levels dropped by day 2. |
32674190 | CT of the lung showed extensive bilateral ground glass opacities.The patient was treated according to a predefined standard, including oxygen supplementation and, after intermittent worsening, with CPAP-ventilation. |
32674191 | The patient was initially treated with highflow oxygen via nasal cannula (HFNC) and CPAP for two days but had to be intubated and mechanically ventilated. […] After discontinuation of ECMO and 11 days of intermittent assisted ventilation via tracheostoma and low dose oxygen (1 l/min), the patient could be transferred to rehabilitation. |
32676371 | Disease severity was determined by the need for supplemental oxygen and mechanical ventilation. […] Patients who needed supplemental oxygen (n=19, 17.4%) were significantly older (P<0.001) and significantly more of them had co-morbidities (P=0.011). […] CRSinitial ≥5 had a sensitivity of 63% and specificity of 92% in predicting the need for oxygen, and 73% sensitivity and 88% specificity in predicting the need for mechanical ventilation.

32678799 | In Montgomery County, Maryland, measurements of oxygen saturation (SpO2) by pulse oximetry obtained by the emergency medical service (EMS) were added to these traditional metrics to enhance the public health picture for decision makers. |
32679582 | Supportive and symptomatic treatments (oxygen therapy and antibiotics for preventing/treating bacterial coinfections) are recommended in these patients. |
32680760 | Included are the first 3 weeks of screening by our physicians for potential exposure to COVID-19, common symptoms, temperature, blood oxygen saturation, and heart rate. |
32680896 | Physical examination, bedside echocardiography, hemodynamic monitoring, lactate and venous oxygen saturation are important components of the patient evaluation. |
32681847 | Accordingly, at many health-care facilities, patients who had increasing oxygen requirements were emergently intubated and mechanically ventilated to avoid exposure to aerosol-generating procedures. |
32684211 | Ramsay score, mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), arterial oxygen partial pressure (PaO2) before sedation and at 1, 12, 24 hours after sedation, sleep time were collected, and the side effects such as excessive sedation, fall of tongue, abdominal distension, aspiration, bradycardia, escalation to invasive mechanical ventilation during 24 hours were also collected. |
32685081 | The patient was afebrile, had an oxygen saturation of 100%, and denied chest pain as well as shortness of breath. |
32685300 | Within a short period after they were administered tocilizumab, their oxygen saturation improved and other inflammatory markers such as D-dimer levels, lactate dehydrogenase, and ferritin levels decreased. |
32685326 | The symptoms started to resolve on pharmacological treatment and supplemental noninvasive oxygen supply over the next weeks. |
32686375 | In our case, we performed tracheostomy for a 70-year-old man with coronavirus disease 2019 (COVID-19) who had required more oxygen with gradual weakness of respiratory muscle to maintain his arterial oxygen saturation. |
32687485 | CASE REPORT A 46-year-old female with past medical history of diabetes mellites, hypertension, and asthma presented in the emergency department (ED) with dyspnea requiring 6 liters per minute of oxygen on presentation. |
32687538 | The capacity of Kenyan hospitals to absorb increases in caseload due to COVID-19 is constrained by the availability of oxygen, with only 58% of hospital beds in hospitals with oxygen supply. […] Additional investments will however need to be strategically prioritized to focus on strengthening essential services first, such as oxygen availability before higher cost investments such as ICU beds and ventilators. |
32687823 | Patients were evaluated for ECMO support based on a partial pressure of arterial oxygen/fraction of inspired oxygen ratio of less than 150 mm Hg or pH of less than 7.25 with a partial pressure of arterial carbon dioxide exceeding 60 mm Hg with no life-limiting comorbidities. |
32690096 | The treatment of patients includes supportive treatment, antiviral treatment, and oxygen therapy. |
32690324 | The process described was equivalent to the oxygen transport system. |
32690356 | There are significant logistical challenges to providing respiratory support devices, beyond simple oxygen flow, when centres run out of supplies or do not have these devices at all, such as in low resource settings. |
32690444 | Ten patients (58.8%) received intranasal oxygen, while 3 (17.6%) received non-invasive mechanical ventilation, and 4 (23.5%) received high-flow oxygen. |
32690572 | The patient was admitted for 1 day; immunosuppressive therapy with tacrolimus and low-dose prednisolone was continued; and the patient recovered successfully without the use of antiviral agents or oxygen therapy. |
32690998 | We present a case of a young veteran who presented with e-cigarette vaping associated lung injury (EVALI) to a primary care clinic and who required subsequent inpatient admission and home oxygen therapy after discharge. |
32692228 | However, a technical standard for oxygen therapy nursing, as well as how this would improve clinical outcomes and symptoms, is yet to be explored. […] Fifteen patients who did not receive oxygen therapy and 13 patients who were transferred from other hospitals were excluded. […] The rest of the 30 patients that received standardized oxygen therapy in our unit were included in the study. […] Baseline characteristics, symptoms, and finger pulse oxygen saturation were collected during hospitalization. […] The fingertip oxygen saturation was 94.80%±3.49% at ICU admission and 97.8%±1.27% when transferred out of ICU after standardized oxygen therapy (P<0.005). […] The standardized oxygen therapy nursing strategy for patients with COVID-19 emphasizes the nursing measurement, which focuses on the patient’s oxygenation. […] It is led by nurses and starts oxygen therapy at an earlier stage. |
32693650 | This retrospective study included patients with severe COVID-19 requiring oxygen therapy who received tocilizumab in seven centers across Poland. […] Sixteen patients (57%) no longer needed oxygen therapy within a week (p < 0.001). |
32695322 | Four of seven (57%) received oxygen therapy, one (14%) received noninvasive and invasive mechanical ventilation, five (71%) received antiviral and antibacterial drugs, three (43%) recieved glucocorticoid therapy and one (14%) received continuous renal replacement therapy. |
32695323 | Eighty percent of patients received supplemental oxygen; none received non-invasive ventilation, one was intubated. |
32696108 | Dexamethasone 6 mg once daily (either by mouth or by intravenous injection) for 10 days may result in a reduction in mortality in COVID-19 patients by one-third for patients on ventilators, and by one-fifth for those receiving oxygen. |
32696443 | Therefore, several empirical oxygenation support initiatives have been initiated with intermittent hyperbaric oxygen (HBO) therapy to overcome the unrelenting and progressive hypoxemia during maximum ventilator support in intubated patients, despite high FiO2. |
32697030 | Following this, the patients’ saturation improved, later to be weaned from oxygen support. |
32698822 | Oxygen saturation to fraction of inspired oxygen ratio (SpO2/FiO2) has been described as potential predictor of poor outcome for COVID-19, without considering its time-varying behavior though. |
32699094 | Severe cases of COVID-19 can result in lung damage, low blood oxygen levels, and even death. |
32699149 | Around the tenth day after diagnosis, ∼20% of patients with coronavirus disease 2019 (COVID-19)-associated pneumonia evolve toward severe oxygen dependence (stage 2b) and acute respiratory distress syndrome (stage 3) associated with systemic inflammation often termed a “cytokine storm.” […] All of the patients treated with anakinra improved clinically (P < 0.01), with no deaths, significant decreases in oxygen requirements (P < 0.05), and more days without invasive mechanical ventilation (P < 0.06), compared with the control group. |
32699167 | In addition to fever and symptom surveillance in the control group, subjects in the intervention group will wear wearable biosensors on their arms to continuously monitor skin temperature, respiratory rate, blood pressure, pulse rate, blood oxygen saturation and daily activities. |
32700604 | This hyperinflammation leads to worsening of oxygen saturation due to pulmonary infiltration and exudation, organ damage, and dysfunction of coagulation pathway and may lead to multi-organ failure. |
32701913 | The multidisciplinary assessment comprises a complete physical examination, respiratory evaluation (peripheral oxygen saturation, respiratory rate, dyspnoea assessment, lung ultrasound and pulmonary function), cardiovascular assessment (electrocardiography, echocardiography), nutritional assessment (anthropometrics, mini Nutritional Assessment screening tool), neurological examination including cognitive tests, and mental health assessment. |
32701969 | Thirty-one percent of patients who were receiving mechanical ventilation at the time of HCQ initiation died during their hospitalization, compared to 18% of patients who were receiving supplemental oxygen but not requiring mechanical ventilation, and 8% of patients who were not requiring supplemental oxygen. |
32702153 | 68.3% received oxygen support; all patients received antiviral therapy, and 15 (36.6%) recipients were additionally treated with intravenous immunoglobulin and interferon-α. |
32702930 | These women began to exhibit fever or reduced blood oxygen saturation again. |
32706108 | In some patients, conventional (passive) oxygen therapy alone is sufficient. […] In patients with worsening respiratory failure high flow nasal oxygen therapy (HFNOT) may be effective. |
32706407 | However, dead spaces would not be sensible to oxygen supplementation, and also, enlargement of pulmonary vessels it has been evidenced. […] Shunt mechanism by vasodilatation, instead, could explain decubitus dependence in oxygenation by blood redistribution as observed in these patients, and moreover, would be more sensible to oxygen supplementation than dead spaces. |
32706769 | CASE REPORT A 48-year-old man with hypertension and type 2 diabetes mellitus presented to the Emergency Department with acute-onset pleuritic chest pain that had developed 1 day earlier and was found to be hypoxemic, requiring supplemental oxygen. […] The patient’s pleuritic pain and oxygen requirements improved with supportive management over the next several days. |
32706859 | Inclusion criteria were similar between studies: patients had confirmed SARS-CoV-2 infection, were hospitalized, had oxygen saturation 94% or lower on room air or required supplemental oxygen, and had pulmonary infiltrates. |
32706953 | We conducted a multicenter, randomized, open-label, three-group, controlled trial involving hospitalized patients with suspected or confirmed Covid-19 who were receiving either no supplemental oxygen or a maximum of 4 liters per minute of supplemental oxygen. |
32707264 | In this clinical trial, conducted in Iran, we enrolled patients with COVID-19 who were older than 60 years and hospitalized to receive supplementary oxygen for their documented pneumonia. […] With a response rate of 80%, whole-lung irradiation in a single fraction of 0.5 Gy had encouraging results in oxygen-dependent patients with COVID-19 pneumonia. |
32707480 | This position paper of the Respiratory Support and Chronic Care Group of the French Society of Respiratory Diseases is intended to help respiratory clinicians involved in care of COVID-19 pandemic in the rational use of non-invasive techniques such as oxygen therapy, CPAP, non-invasive ventilation and high flow oxygen therapy in managing patients outside intensive care unit (ICU). |
32707945 | It seems that the stimulation of a proinflammatory cascade and the production of large amounts of reactive oxygen species culminates in the subsequent loss of host eubiosis. |
32708430 | The inflammatory response manifested by increased cytokine levels and reactive oxygen species results in inhibition of heme oxygenase (HO-1), with a subsequent loss of cytoprotection. |
32708578 | A common denominator in all conditions associated with COVID-19 appears to be the impaired redox homeostasis responsible for reactive oxygen species (ROS) accumulation; therefore, levels of glutathione (GSH), the key anti-oxidant guardian in all tissues, could be critical in extinguishing the exacerbated inflammation that triggers organ failure in COVID-19. |
32709637 | Outcome measures were level of oxygen therapy, discharge and death. |
32709838 | Her vital signs were normal except for oxygen saturation of 87% and bilateral rhonchi on lung auscultation. |
32710297 | Such programs include diagnostic procedures (spirometry, ECG, blood tests) and treatments like respiratory physio-kinesiotherapy and postural drainage of the lungs; mechanical pulmonary ventilation for rehabilitative purposes, with or without drugs, along with standard medical and, when required, oxygen therapy; inhalation therapies with mineral waters; physical activity and psychological support. |
32710975 | High IL-6 level, C-reactive protein level, lactate dehydrogenase (LDH) level, ferritin level, d-dimer level, neutrophil count, and neutrophil-to-lymphocyte ratio were all predictive of mortality (area under the curve >0.70), as were low albumin level, lymphocyte count, monocyte count, and ratio of peripheral blood oxygen saturation to fraction of inspired oxygen (SpO2/FiO2). |
32712235 | He was tachypneic and presented severe hypoxemia (75% percutaneous oxygen saturation). |
32713377 | During the peak of COVID-19 attendance, the ED faced an extraordinary increase in: patients needing oxygen (+239%) or NIV (+725%), transfers to the intensive care unit (+57%), and in-hospital mortality (+309%), as compared to the same period in 2019. |
32714705 | His PaO2/FiO2 (P/F) was under 100, even with tracheal intubation with 100% oxygen. |
32715804 | Given the persistent hypoxemia despite oxygen therapy via non rebreather face mask (FiO2:80%), convalescent plasma transfusion was administered that led to a mild clinical improvement as well as decrease in inflammatory markers. |
32717853 | Reactive oxygen species (ROS) promoting molecules such as peroxides are detrimental to many viruses, including coronaviruses. |
32720612 | Shortness of breath considerably decreased; oxygen saturation increased, and the NEWS-2 clinical status scale scores decreased. |
32721528 | IL6ri were initially reserved for critically ill patients, but after review, treatment was liberalized to patients with lower oxygen requirements. […] Patients were divided into two groups: those requiring ≤45% fraction of inspired oxygen (FiO2) (termed stage IIB) and those requiring >45% FiO2 (termed stage III) at the time of IL6ri administration. |
32723327 | Preserved oxygen saturation despite low partial pressure of oxygen in arterial blood samples occur, due to leftward shift of the oxyhemoglobin dissociation curve induced by hypoxemia-driven hyperventilation as well as possible direct viral interactions with hemoglobin. |
32723435 | The overall outcome was severe, with high frequencies of hospitalisation (69.8%), respiratory support oxygen (55.7%), non-invasive ventilation (20.9%) or mechanical ventilation (7.5%), and 19% of deaths. |
32723449 | Supplemental oxygen, high flow nasal canula, non-invasive ventilation and endotracheal intubation are the most commonly suggested methods to improve oxygenation. |
32726724 | Thoracic computed tomography (CT) was performed on admission, when oxygen support was necessary, and seven days after TCZ started. […] The median duration of oxygen support before the onset of TCZ was shorter among the severe patient group than the critical patient group (1 vs. 4 days, p < 0.001). […] Earlier use of TCZ in COVID-19 infection was beneficial for survival, length of hospitalization and duration of oxygen support. […] The recommendation for administration of TCZ was based on an increase in requirement of oxygen support, progression in thoracic CT, and elevation of inflammation markers, including IL-6, CRP, ferritin, and d-dimer, and decrease in % lymphocytes. |
32727624 | The trial objective is to determine if Continuous Positive Airway Pressure (CPAP) or High-Flow Nasal Oxygen (HFNO) is clinically effective compared to standard oxygen therapy in patients with confirmed or suspected COVID-19. […] 1) Adults ≥ 18 years; 2) Admitted to hospital with suspected or proven COVID-19; 3) Receiving oxygen with fraction of inspired oxygen (FiO2) ≥0.4 and peripheral oxygen saturation (SpO2) ≤94%; and 4) Plan for escalation to tracheal intubation if needed. […] Intervention two: High-flow nasal oxygen delivered by any device. […] Comparator group: Standard care- oxygen delivered by face mask or nasal cannula (excluding the use of continuous positive airway pressure or high-flow nasal oxygen). […] Participants are randomised in a 1:1:1 ratio to receive either continuous positive airway pressure, high-flow nasal oxygen or standard care. |
32728438 | Adverse outcomes analysed included supplemental oxygen use, intensive care unit admission, mechanical ventilation and mortality, with the primary endpoint a composite of any of these. |
32728966 | Secondary objectives were to test the association between LUS score and location of the patient, use of mechanical ventilation, and the pulse oximetry (SpO2)/fractional inspired oxygen (FiO2) ratio. |
32730358 | Five significant variables predicting ICU admission were lactate dehydrogenase, procalcitonin, pulse oxygen saturation, smoking history, and lymphocyte count. […] Seven significant variables predicting mortality were heart failure, procalcitonin, lactate dehydrogenase, chronic obstructive pulmonary disease, pulse oxygen saturation, heart rate, and age. |
32730678 | All patients had a high C-reactive protein value. 64% of patients required oxygen support and 32% intensive care. 28% developed a secondary infection. 76% (19/25) of the patients has been discharged with cure and 20% (5/25) died. […] Secondary infection development was significantly associated with oxygen demand (P = 0.027) and need for intensive care (P = 0.001). |
32731283 | Poor oxygen saturation (< 88 %) and increased signs of inflammation (CRP > 97 mg/l and/or IL-6 > 80 pg/ml) indicate a critical course and should be determined in symptomatic patients. |
32733907 | All the patients had fever, required non-invasive oxygen therapy and presented a CT lung involvement on imaging more than 50%. […] Results: The two cohorts of patients were comparable for age, sex, laboratory values, concomitant pathologies, and the modality of oxygen support. |
32736596 | The study will include hospitalised adult patients (≥18 years) with confirmed SARS-CoV-2 infection, the virus that causes COVID-19, that clinically meet Grades 3 (hospitalised - mild disease, no oxygen therapy), Grades 4 (hospitalised, oxygen by mask or nasal prongs) and 5 (hospitalised, non-invasive ventilation or high flow oxygen) of the WHO Working Group on the Clinical Characteristics of COVID-19 9-point category ordinal scale. |
32738287 | We collected sociodemographic information, clinical data, baseline inflammatory markers and follow-up oxygen saturation levels. |
32738843 | One patient needed oxygen support while hospital course was uncomplicated in the rest. |
32739471 | Activated vascular endothelial cells become a source of proinflammatory cytokines and reactive oxygen species (ROS) and contribute to the development of coagulopathy, systemic sepsis, a cytokine storm and ARDS. |
32740128 | Gas blender attached to ECMO is used to allow precise adjustment of characteristics of fresh gas flow, i.e. blood oxygen delivery and carbon dioxide removal. […] In order to cope with the gas blender shortage, we describe a back-up system set up in our French tertiary referral ECMO center using air and oxygen flowmeters. |
32743995 | Disease severity scores were defined as: 1) no limitation of daily activities; 2) limitation of daily activities but no need for supplemental oxygen; 3) supplemental oxygen via nasal cannula; 4) supplemental oxygen via facial mask; 5) non-invasive mechanical ventilation; 6) invasive mechanical ventilation; 7) multi-organ failure or extracorporeal membrane oxygenation therapy; and 8) death. […] In Korea, almost all patients of < 50 years of age with COVID-19 recovered without supplemental oxygen. |
32745862 | Singlet oxygen (1O2) is a reactive oxygen species that plays important role in bacteria/virus inactivation and pollutant degradation. […] It was confirmed that irradiation of the RB filter under oxygen gas stream produced 1O2, which was measured using furfuryl alcohol trapping method followed by HPLC analysis. |
32745895 | PaO2/FIO2 ratio and oxygen saturation (SaO2) were decreased in critically ill patients. |
32747596 | A 60-year-old man with swab-positive COVID-19 and extensive ground-glass change seen on CT imaging was successfully managed on our COVID-19 high-dependency unit with only low-flow oxygen and strict awake proning instructions. […] He was successfully weaned off oxygen entirely without any requirement for non-invasive or invasive ventilation and made a recovery to be discharged home after an 18-day hospital stay. |
32752010 | Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causes the corona virus disease-19 which is accompanied by severe pneumonia, pulmonary alveolar collapses and which stops oxygen exchange. |
32753516 | Review of the records revealed 138 (92%) patients had pulmonary infiltrates on chest radiography, and 146 (97%) required oxygen therapy. |
32754041 | Cellular therapy, along with organ support systems such as oxygen therapy, artificial ventilation, extra corporeal membrane oxygenation and dialysis, as well as antiviral therapy, are required. |
32755117 | HFNC provides higher concentration and flow of oxygen, resulting in decreasing anatomic dead space by preventing rebreathing and ensure positive end-expiratory. […] The available reports suggest that HFNC provides high concentrations of oxygen to the patients, who can not reach with conventional devices. […] Besides that, the use of high-flow oxygen cannulas can produce aerosols. |
32755653 | Pulmonary computerized tomography (CT)-scans were performed significantly more often with time (from 50% to 90%, P<0.0001), and oxygen-dependency (53% vs 80%, P=0.001) and prescription of AZI±HCQ (from 25% to 76%, P<0.0001) were also greater over time. […] The present study showed a significant decrease in admission to ICU over time, which was probably related to multiple factors, including a better indication of pulmonary CT-scan, oxygen therapy, and a suitable prescription of anti-infective agents. |
32755777 | The Biological Oxygen Demand and Chemical Oxygen Demand values reduced by 42.83% and 39.25%, respectively, compared to the pre-lockdown phase, while Faecal Coliform declined by over 40%. |
32756215 | The patient was treated with a moderate dose of intravenous corticosteroids and high-flow nasal cannula oxygen therapy. |
32757500 | Five patients required supplemental oxygen and one required mechanical ventilation. |
32758659 | Seventeen factors were independently associated with an increased hazard of death, the strongest among them including advanced age, liver cirrhosis, low age-adjusted oxygen saturation, higher concentrations of C-reactive protein and lower estimated glomerular filtration rate. |
32758842 | The impact could be seen in terms of increased dissolved oxygen (DO) and reduced biological oxygen demand (BOD), Faecal coliform, Total coliform and nitrate (NO3-) concentration. |
32758897 | We observed too, the markedly reduced local inflammation in the airways after administering NIH lays on its ability to inhibit the enzyme cyclooxygenase and to markedly diminish reactive oxygen species (ROS). |
32758904 | N-acetylcysteine is one such drug with potency to scavenge Reactive Oxygen Species, least side effects, and an effective precursor of glutathione. |
32761491 | With MSC transplantation, the fraction of inspired O2 (FiO2) of the two patients gradually decreased while the oxygen saturation (SaO2) and partial pressure of oxygen (PO2) improved. |
32762665 | Patients with severe/critically ill COVID-19 were more likely to be older, to be single onset (i.e. not belong to a cluster of cases in a family/community, etc.), to have a medical history of hypertension and diabetes; had higher temperature, faster respiratory rates, lower peripheral capillary oxygen saturation (SpO2), and higher computer tomography (CT) image quadrant scores and pulmonary opacity percentage; had increased C-reactive protein, fibrinogen, and D-dimer on admission; and had lower white blood cells, lymphocyte, and platelet counts and albumin on admission than asymptomatic/mild/moderate cases. |
32762737 | Daily body temperature and oxygen saturation were recorded as markers of disease severity alongside need for hospitalisation. […] The correlation between chemosensitive scores and oxygen saturation was significant only for taste at T2 (p < 0.001). |
32762885 | Multiple pathways have been suggested to explain this finding and the related clinical scenarios, encompassing local and systemic inflammatory responses and oxygen supply-demand imbalance. |
32763089 | Anesthesia nurses have their own professional specialties, such as airway management, the use and maintenance of life support equipment, including ventilators, and the use of high-flow oxygen equipment. |
32763101 | He had rapidly evolving ARDS [partial arterial pressure of oxygen to fractional inspired concentration of oxygen ratio: 175], and sepsis. |
32763657 | Human Coronavirus (HCoV) infection causes infiltration of inflammatory cells that cause excessive production of cytokines, proteases, coagulation factors, oxygen radicals and vasoactive molecules causing endothelial damage, disruption of fibrous cap and initiation of formation of thrombus. |
32764134 | We calculated oxygen consumption (OC). […] There was no significant increase in oxygen during ship transport and no major respiratory complication. […] There was no significant increase in arterial oxygen pressure to fractional inspired oxygen ratio among ventilated patients during ship transport. |
32765959 | Roughly 71.4% of the older adults require supplementary oxygen, while invasive mechanical ventilation was required in almost a third of the reported hospitalized older individuals. […] Risk for mortality is evident, and attention to the need for supplementary oxygen and possible mechanical ventilation is advised. |
32766535 | Seven patients received high-flow nasal cannula oxygen therapy and five received non-invasive mechanical ventilation for lung complications of COVID-19. |
32766565 | Patients treated with oxygen were assigned to the moderate group (n = 13). |
32766567 | The strongest combination of clinical, chest radiograph, and lung ultrasound factors for diagnosis was nondependent bilateral pulmonary edema pattern with temperature and oxygen saturation (area under the curve, 0.86; 95% CI, 0.76-0.94; sensitivity = 77% [58-93%]; specificity = 76% [53-94%] at the ideal cutoff), which was superior to chest radiograph alone. |
32767353 | Outcome indicators were death or LOS, and laboratory parameters, e.g., variations in C-reactive protein (CRP) levels, ratio of arterial oxygen partial pressure (PaO2, mmHg) to fractional inspired oxygen (FiO2) (PaO2/FiO2), and leucocyte count. |
32768701 | Clinical characteristics and outcomes were retrospectively analysed of patients - with laboratory-confirmed bilateral COVID-19 pneumonia, hyperinflammation (C-reactive protein (CRP) ≥20 mg/dL), no hypoxaemia (oxygen saturation >90%), and no contraindications to TCZ - who were treated with subcutaneous TCZ (324 mg) administered within 48 h from hospitalization on top of standard of care (SOC). […] TCZ resulted in a parallel improvement in oxygenation, as assessed by the ratio of partial pressure of oxygen to fraction of inspired oxygen (P/F) ratio, which increased at day 1 (+11%, IQR +6 to +16; p = 0.005 for within-group and p = 0.006 for between-group comparisons), and day 3 (+23%, IQR +16 to +34; p = 0.005 for within-group and p = 0.003 for between-group comparisons). […] None of the TCZ-treated patients had disease progression, defined as requirement of oxygen therapy or mechanical ventilation, whereas progression occurred in five (50%) patients among the SOC group. |
32768971 | The clinical management of COVID-19 has been limited to infection prevention and control measures associated with supportive care such as supplemental oxygen and mechanical ventilation. |
32769659 | Recent evidence supports the use of an early, short course of glucocorticoids in patients with COVID-19 who require mechanical ventilation or oxygen support. |
32770858 | The viral infection leads to severe lack of oxygen, lung oxidative stress because of reactive oxygen species generation, and overactivation of the immune system by activating immune mediators. |
32771461 | Therapeutic approaches based on these principles include 1) reduction of reinoculation, 2) combination antiviral therapy, 3) immunomodulation, 4) antiplatelet/antithrombotic therapy, and 5) administration of oxygen, monitoring, and telemedicine. |
32771635 | Patients with anosmia had pneumonia less often (10/37 vs 17/33, p = 0.036), were hospitalized less often (13/37 vs 20/33, p = 0.033), and needed oxygen therapy less often (6/37 vs 17/33, p = 0.002) than patients without anosmia. |
32771883 | Factors predicting survival were a female sex (OR 0.271; 0.128-0.575, p = 0.001), previous treatment with RAAS inhibitors (OR 0.459; 0.222-0.949, p = 0.036), a higher oxygen saturation at admission (OR 0.901; 0.842-0.963 per percentage point increase, p = 0.002), and a greater platelet count (OR 0.995; 0.991-0.999 per 106/L, p = 0.025). |
32772283 | Additionally, preexisting cardiovascular disease, malignancy, blood oxygen saturation < 90%, leukocytosis, and lymphopenia at presentation were independently associated with a greater risk of developing cardiac injury. |
32773102 | In this review, we suggest that the overwhelming production of reactive oxygen species (ROS) resulting in oxidative stress is a major cause of local or systemic tissue damage that leads to severe COVID-19. |
32773414 | Only five (3.5%) patients required oxygen supplementation, four (2.8%) patients had severe disease requiring intensive care, one required mechanical ventilation and mortality occurred in two (1.4%) patients. |
32773848 | High flow nasal oxygen, face mask ventilation, nebulisation, small bore cannula cricothyroidotomy with jet ventilation should be avoided. |
32774178 | At present, COVID-19 is managed by available antiviral drugs to improve the symptoms, and in severe cases, supportive care including oxygen and mechanical ventilation is used for infected patients. |
32775071 | Awake proning delays the use of mechanical ventilation and facilitates the patients with severe ARDS or severe pneumonia in maintaining the supply of oxygen to the body tissues. |
32775986 | Hydroxychloroquine was administered to 15 patients. 11 patients required supplemental oxygen; 2 of them were admitted to an intensive care unit (ICU) with mechanical ventilation. |
32776298 | Hospitalized patients ≥18 years old with severe coronavirus disease 2019 (COVID-19) were treated with either HCQ or LPV/RTV if they had either respiratory insufficiency (SpO2 ≤ 93% on room air or the need for oxygen insufflation) or bilateral consolidations on chest X‑ray and at least 2 comorbidities associated with poor COVID-19 prognosis. |
32776617 | Once SARS-CoV-2 enters the blood stream, a cascade of events (Steps 1-8) unfolds including accumulation of angiotensin II, reactive oxygen species, endothelial dysfunction, oxidation of beta 2 glycoprotein 1, formation of antiphospholipid antibody complexes promoting platelet aggregation, coagulation cascade, and formation of cross-linked fibrin blood clots, leading to pulmonary emboli (PE) and large vessel strokes seen on angiographic imaging studies. |
32777054 | The five double-elite enhancer/promoters that are known to be operational, and shared read-through lncRNA transcripts, imply that ongoing SARS-CoV-2 infection will reduce host defences to reactive oxygen species, directly generate superoxide O2 - and H2O2 (a “ROS storm”), and impair pulmonary endothelial homeostasis. |
32777268 | Platypnea-orthodeoxia syndrome (POS) is a rare clinical syndrome characterized by orthostatic oxygen desaturation and positional dyspnea from supine to an upright position. […] POS was first observed during physiotherapy sessions; median oxygen desaturation was 8 % (range: 8-12 %). |
32779309 | Insufficiency of angiotensin converting enzyme 2 in pregnant women and the effects of hypoxia on the placental oxygen supply will cause severe perinatal complications. |
32779728 | We will allocate 1000 adult patients with COVID-19 receiving ≥10 L/min of oxygen or on mechanical ventilation to intravenous hydrocortisone 200 mg daily vs placebo (0.9% saline) for 7 days. |
32779828 | Our objective was to evaluate patient-reported oxygen saturation (SpO2) using pulse oximetry as a home monitoring tool for patients with initially non-severe COVID-19 to identify need for hospitalization. |
32779925 | Data were collected on diagnostic status (COVID-19: confirmed/excluded (using the RT-PCR test)), symptomatology (typical/atypical and other symptoms, body temperature and oxygen saturation) and, in the case of confirmed COVID-19, on disease course (recovered/clinically improved/deteriorated, deceased). |
32781167 | Venous oxygen saturation was frequently measured (79%), mostly from a CVC blood sample (94%). |
32784238 | On initial assessment the patient was hypoxic (arterial oxygen saturation (SaO2) of 86% on room air), requiring 10 L/min of oxygen to maintain 98% SaO2 Examination demonstrated left-sided tracheal deviation and absent breath sounds in the right lung field on auscultation. |
32784240 | However, with the patient requiring an increasing fraction of inspired oxygen (FiO2), a prompt CT pulmonary angiogram scan was performed to exclude an acute pulmonary embolism. |
32785285 | Multivariate regression identified the amount of supplemental oxygen required at admission (OR: 1.208, 95% CI: 1.011-1.443, p = .037), sputum production (OR: 6.734, 95% CI: 1.630-27.812, p = .008), insulin dependent diabetes mellitus (OR: 11.873, 95% CI: 2.218-63.555, p = .004) and chronic kidney disease (OR: 4.793, 95% CI: 1.528-15.037, p = .007) as significant risk factors for intensive care unit admission or death. […] Patients with increased sputum production and higher supplemental oxygen requirements at admission, and insulin dependent diabetes or chronic kidney disease may be at increased risk for severe illness. |
32787397 | The treatment of severely ill coronavirus disease 2019 (COVID-19) patients has brought the worldwide shortage of oxygen and ventilator-related resources to public attention. […] Most patients need oxygen and supportive therapy. […] In Africa, the shortage of oxygen is even more severe and needs equipment that is simpler to use than a ventilator. […] Different models of generating oxygen locally at hospitals, including at provincial and district levels, are required. […] In some countries, hospitals have established small oxygen production plants to supply themselves and neighbouring hospitals. […] Oxygen concentrators have also been explored but require dependable power supply and are influenced by local factors such as ambient temperature and humidity. […] The local and regional energy unleashed in the citizens to respond to the COVID-19 pandemic should now be directed towards developing appropriate infrastructure for oxygen and critical care. |
32788008 | All patients had a positive nucleic acid test for 2019 novel coronavirus (2019-nCoV), and were discharged after clinical treatment with oxygen therapy, antiviral, antibacterial, anti-inflammatory, and nutritional support. |
32788025 | To make a new simple respirator and observe the oxygen therapy effect of the respirator on patients with severe and critical coronavirus disease 2019 (COVID-19). […] Based on the infectivity and hospital requirements of COVID-19, a new simple respirator was designed by the medical staff of the Department of Anesthesiology of the Second Affiliated Hospital of Nanchang University, which was applied on the 22 patients with severe and critical COVID-19 who needed oxygen therapy admitted to the Cancer Center of Tongji Medical College of Huazhong University of Science and Technology from February 15th to March 15th in 2020. […] The new simple respirator contained two National Utility Model Patents (a respirator: ZL 2015 2 0410623.6, a fluid switch and oxygen suction device: ZL 2017 2 0873509.6), which was mainly composed of anesthesia mask and filter, L-shaped connecting tube, soft breathing bladder, connecting tube and elastic fixing belt. […] When in use, the anesthesia mask was fixed to the patient’s mouth and nose with elastic straps, the connecting tube was inserted into the oxygen meter interface, the oxygen flow was adjusted to 6-10 L/min, and the L-shaped connecting tube was opened immediately after the soft breathing bag was full. […] The carbon dioxide and excess oxygen in the body was discharged from exhaust port. […] The oxygen flow was lowered to 2-3 L/min, the patient’s respiratory rate (RR) was observed through the soft breathing bag fluctuations, and the oxygen flow was adjusted at any time. […] The changes of pulse oxygen saturation (SpO2), RR and heart rate (HR) before and after application of new simple respirator were observed, and the blood gas test results of part of the patients were collected. […] The new simple respirator can significantly improve the oxygen therapy effect of patients with severe and critical COVID-19. |
32789084 | Sore throat (25%), fatigue (25%), and low oxygen saturation (25%) were present in one patient which prompted us to get the COVID-19 test. |

32805728 | Bioinformatics findings indicate that the mechanisms of action of VA against SARS-CoV-2 include enrichment of immunoreaction, inhibition of inflammatory reaction, and biological processes related to reactive oxygen species. |
32808513 | Patients were classified into mild and non-mild groups on initial admission according to oxygen demand and Sequential Organ Failure Assessment score, and the mild group was followed up and subgrouped into non-aggravation and aggravation groups. |
32808941 | Metabolic rates, carbon dioxide production and oxygen consumption were measured by indirect calorimetry. […] Mild hypothermia decreased the REE on average of 27.0% with resultant declines in CO2 production (VCO2) and oxygen consumption (VO2) by 29.2% and 25.7%, respectively. |
32809050 | In stable patients with oxygen treatment (stage I) HCQ (18.3%), azithromycin (16.9%) and Ig (9.9%) were most frequently used. |

[…] Nearly half of the patients presented with severe and critical disease and required high-flow nasal oxygen or invasive mechanical ventilation at admission. |
32812204 | Patients with severe COVID-19 at admission, based on low oxygen saturation, low partial arterial oxygen pressure, were excluded. […] The most contributory variables to the models were APACHE II score, white blood cell count, time from symptoms to admission, oxygen saturation and blood lymphocytes count. |
32814566 | The current target oxygen saturation range for patients with COVID-19 recommended by the National Institutes of Health is 92-96%. […] This article critically examines the evidence guiding current target oxygen saturation recommendation for COVID-19 patients, and raises important concerns in the extrapolation of data from the two studies stated to be guiding the recommendation. […] Finally, it discusses potential implications of specific clinical observations and considerations in COVID-19 patients on target oxygen saturation, such as diffuse systemic endothelitis and microthrombi playing an important pathogenic role in the wide range of systemic manifestations, exacerbation of hypoxic pulmonary vasoconstriction in the setting of pulmonary vascular endothelitis/microthrombi, the phenomenon of “silent hypoxemia” with some patients presenting to the hospital with severe hypoxemia disproportional to symptoms, and overburdened health systems and public health resources in many parts of the world with adverse implications on outpatient monitoring and early institution of oxygen supplementation. […] The above factors and analyses, put together, call for an urgent exploration and re-evaluation of target oxygen saturation in COVID-19 patients, both in the inpatient and outpatient settings. […] Until data from such trials become available, where possible, it may be prudent to target an oxygen saturation at least at the upper end of the recommended 92-96% range in COVID-19 patients both in the inpatient and outpatient settings (in patients that are normoxemic at pre-COVID baseline). […] Home pulse oximetry, tele-monitoring, and earlier institution of oxygen supplementation for hypoxemic COVID-19 outpatients could be beneficial, where public health resources allow for their implementation. |
32814839 | Patients had severe pulmonary disease defined by pulmonary infiltrates on imaging and an oxygen saturation ≤ 93% in air and/or PaO2/FiO2 ratio ≤ 300 mmHg. […] Clinical improvement was not affected by low-flow versus high-flow oxygen support but was less frequent in patients with PaO2/FiO2 < 200 mmHg. |
32815344 | The patients were categorised in three groups on the basis of the treatment they received for respiratory failure (oxygen alone, supplemental non-invasive ventilation (NIV), and intubation/ventilator) and described using descriptive statistics. […] Eleven patients received ventilator treatment, seven oxygen by mask, and four supplemental NIV. […] All patients treated with oxygen and NIV were alive and had been discharged from hospital. […] For many patients with COVID-19 respiratory failure and need for intensive care, increased oxygen and NIV are sufficient, but the need for intubation must be continuously assessed. |
32815354 | A total of 49 patients (67 %) had hypoxaemia and required oxygen therapy for an average of 10.1 days. […] The majority of the patients hospitalised with COVID-19 needed prolonged oxygen therapy, and there was a high incidence of severe complications. |
32815513 | The acute respiratory phase in both patients was treated with supplemental oxygen. |
32815745 | Background: Since partial oxygen pressure decreases as altitude increases, environmental hypoxia could worsen Coronavirus Disease 2019 (COVID-19) patient’s hypoxemia. |
32816059 | Compassionate treatment with a single 1‑Gy dose to the bilateral whole-lung volume was administered, with gradual daily improvement of ventilatory function and decrease in serum inflammatory markers and oxygen support needs, including intubation. |
32816615 | Various scientific studies demonstrated that Sumac had a free oxygen radical-scavenging effect, a protective effect against liver damage, antihemolytic, leukopenia, and antifibrogenic effects, along with its antiviral, antimicrobial, anti-inflammatory, and antioxidant properties. |

32821939 | Randomized, open-label trial of hospitalized patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and moderate COVID-19 pneumonia (pulmonary infiltrates and room-air oxygen saturation >94%) enrolled from March 15 through April 18, 2020, at 105 hospitals in the United States, Europe, and Asia. |
32822208 | Rationale: Aerosol generation with modes of oxygen therapy such as high-flow nasal cannula and noninvasive positive-pressure ventilation is a concern for healthcare workers during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. […] The amount of aerosol generation from the respiratory tract with these various oxygen modalities is unknown.Objectives: To measure the size and number concentration of particles and droplets generated from the respiratory tract of humans exposed to various oxygen delivery modalities.Methods: Ten healthy participants with no active pulmonary disease were enrolled. […] Oxygen modalities tested included nonhumidified nasal cannula, face mask, heated and humidified high-flow nasal cannula, and noninvasive positive-pressure ventilation. […] Aerosol generation was measured with each oxygen mode while participants performed maneuvers of normal breathing, talking, deep breathing, and coughing. […] This was the case during normal breathing, talking, deep breathing, and coughing.Conclusions: Oxygen delivery modalities of humidified high-flow nasal cannula and noninvasive positive-pressure ventilation do not increase aerosol generation from the respiratory tract in healthy human participants with no active pulmonary disease measured in a negative-pressure room. |
32822564 | Exact logistic regression was used to examine the association between the infection groups and the development of hypoxia requiring supplemental oxygen (an indicator of severe COVID-19, the primary endpoint). […] Development of hypoxia requiring supplemental oxygen was less frequent in the ∆382 variant group (0 [0%] of 29 patients) than in the wild-type only group (26 [28%] of 92; absolute difference 28% [95% CI 14-28]). […] After adjusting for age and presence of comorbidities, infection with the ∆382 variant only was associated with lower odds of developing hypoxia requiring supplemental oxygen (adjusted odds ratio 0·07 [95% CI 0·00-0·48]) compared with infection with wild-type virus only. |
32823497 | Furthermore, both hesperidin and ascorbic acid counteract the cell damaging effects of the oxygen free radicals triggered by virus infection and inflammation. |
32826432 | However, the clinical effectiveness of early high-flow nasal oxygen treatment in patients with coronavirus disease 2019 with acute hypoxemic respiratory failure has not been explored. […] This study aimed to analyze the effectiveness of high-flow nasal oxygen treatment and to identify the variables predicting high-flow nasal oxygen treatment failure in coronavirus disease 2019 patients with acute hypoxemic respiratory failure. […] Forty-three confirmed coronavirus disease 2019 adult patients with acute hypoxemic respiratory failure treated with high-flow nasal oxygen. […] High-flow nasal oxygen failure (defined as upgrading respiratory support to positive pressure ventilation or death) was observed in 20 patients (46.5%), of which 13 (30.2%) required endotracheal intubation. […] Patients with high-flow nasal oxygen success had a higher median oxygen saturation (96.0% vs 93.0%; p < 0.001) at admission than those with high-flow nasal oxygen failure. […] High-flow nasal oxygen failure was more likely in patients who were older (p = 0.030) and male (p = 0.037), had a significant increase in respiratory rate and a significant decrease in the ratio of oxygen saturation/FIO2 to respiratory rate index within 3 days of high-flow nasal oxygen treatment. […] In a multivariate logistic regression analysis model, male and lower oxygen saturation at admission remained independent predictors of high-flow nasal oxygen failure. […] The hospital mortality rate of the cohort was 32.5%; however, the hospital mortality rate in patients with high-flow nasal oxygen failure was 65%. […] High-flow nasal oxygen may be effective for treating coronavirus disease 2019 patients with mild to moderate acute hypoxemic respiratory failure. […] However, high-flow nasal oxygen failure was associated with a poor prognosis. […] Male and lower oxygenation at admission were the two strong predictors of high-flow nasal oxygen failure. |

[…] Patients 1 and 2 received mechanical ventilation with a closed suction system, while patient 3 received high-flow oxygen therapy and non-invasive ventilation. |
32831319 | Since maybe not all COVID-19 neurological manifestations are due to SARS-CoV-2 direct effects, it is important to monitor the rest of the clinical parameters such as, for example, oxygen saturation. |
32832735 | His pulse was 54 beats/min, oxygen saturation was 99%, arterial blood pressure was 122/82 mmHg, and fever was 36.5°C. |
32833671 | One-hundred(91.7%) patients required oxygen therapy, which improved percutaneous oxygen saturation (SpO2). […] Our findings suggest that oxygen plays an important role in the treatment of COVID-19 patients and that age and underlying diseases are significant risk factors for COVID-19. |
32833773 | Respiratory failure due to the virus should be managed by providing supplemental oxygen and early intubation. |
32835245 | The other inclusion criteria were either laboratory-confirmed SARS-CoV-2 or typical lung infiltrates on a lung CT scan, and either an oxygen saturation of 93% or less under oxygen 6 L/min or more, or aggravation (saturation ≤93% under oxygen 3 L/min) with a loss of 3% of oxygen saturation in ambient air over the previous 24 h. |
32835257 | All patients were treated with the standard of care (ie, supplemental oxygen, hydroxychloroquine, azithromycin, antiretrovirals, and low molecular weight heparin), and a non-randomly selected subset of patients also received tocilizumab. |
32835272 | Coronary angiography was performed with the patient in prone (face down) position, owing to the necessity to maintain a reasonable oxygen saturation during the examination. |
32836648 | I organize these directions and considerations into two sets of five each: focal groups that should be studied-i.e., underprivileged populations, different countries and cultural contexts, women (vs. men), workers in healthcare (frontline workers), elderly and at-risk-and five general issues and special considerations-i.e., role of technology as the oxygen, pre- vs. mid- vs. post-COVID studies, constraints on data collection/research due to COVID, evolution of COVID, and focus on contextualization (generalizability is irrelevant). |

32838144 | On day 4, rapid clinical deterioration associated to a high respiratory rate and increased oxygen requirements was noted. […] Oxygen was administered at a rate of 15 litres per minute via a Boussignac valve, which initially restored normal oxygen saturation, but this treatment was poorly tolerated and the patient withdrew it after 2 h. […] We would like to encourage the use of CPAP, better tolerated for extended hours with lower oxygen flows, in patients with COVID-19 pneumonia, where acute respiratory distress all too often leads to patient intubation and the genesis of deleterious lung lesions. |
32838170 | The objective of this review is to enhance the awareness regarding the safety aspects towards infection prevention practices and to offer solutions for safe patient care practices including side effects of disinfectants and precaution in specific medical facilities especially in hemodialysis rooms, intensive care unit, hyperbaric oxygen therapy (HBO) chambers, or patient transport vehicle. |

32852405 | Acute kidney injury occurred in 19% of patients, and 45% required supplementary oxygen. |
32854630 | We found that remarkably decreased ventilatory efficiency (e.g., the ratio of dead space to tidal volume 70-80%, arterial to end-tidal CO2 difference 18-23 mmHg and ventilatory ratio 3-4) and hypermetabolism (oxygen consumption 300-400 ml/min, CO2 elimination 200-300 ml/min) may explain why these patients experienced more severe respiratory distress and CO2 retention in the late phase of ARDS caused by COVID-19. |

[…] The present study suggests that among COVID-19 patients, lung ultrasound and HRCT findings agree in quantifying lung involvement and oxygen parameters. |
32856707 | Disease severity was correlated with results from viral culture, serologic testing, and immune markers. 57 (57%) patients developed viral pneumonia, of whom 20 (20%) required supplemental oxygen including 12 (12%) invasive mechanical ventilation. |

32866898 | While most of the infected individuals show minimal or no symptoms and recover spontaneously, a small proportion of the patients exhibit severe symptoms characterized by extreme dyspnea and low tissue oxygen levels, with extensive damage to the lungs referred to as acute respiratory distress symptom (ARDS). |
32868092 | Non medication based interventions including hyperbaric oxygen (HBOT), extracorporeal membrane oxygenation (ECMO), aggressive dialysis, and other interventions, all with various degrees of clinical success, and will be discussed in this section. |
32868974 | Oxygen saturation at rest was 93%. |
32868978 | The preprint of day-7 interim results by the investigators concluded, "In a small pilot trial of 5 oxygen-dependent patients with COVID-19 pneumonia, low-dose whole-lung radiation led to rapid improvement in clinical status, encephalopathy, and radiographic infiltrates without acute toxicity or worsening the cytokine storm. |
32869227 | CRP was moderately elevated and oxygen saturation was slightly reduced. |
32870512 | Supplemental oxygen is frequently administered to patients with acute respiratory distress syndrome (ARDS), including ARDS secondary to viral illness such as coronavirus disease 19 (COVID-19). […] An up-to-date understanding of how best to target this therapy (e.g. arterial partial pressure of oxygen (PaO2) or peripheral oxygen saturation (SpO2) aim) in these patients is urgently required. […] To address how oxygen therapy should be targeted in adults with ARDS (particularly ARDS secondary to COVID-19 or other respiratory viruses) and requiring mechanical ventilation in an intensive care unit, and the impact oxygen therapy has on mortality, days ventilated, days of catecholamine use, requirement for renal replacement therapy, and quality of life. […] We included RCTs comparing supplemental oxygen administration (i.e. different target PaO2 or SpO2 ranges) in adults with ARDS and receiving mechanical ventilation in an intensive care setting. […] We excluded studies exploring oxygen administration in patients with different underlying diagnoses or those receiving non-invasive ventilation, high-flow nasal oxygen, or oxygen via facemask. […] We identified one completed RCT evaluating oxygen targets in patients with ARDS receiving mechanical ventilation in an intensive care setting. […] The study randomized 205 mechanically ventilated patients with ARDS to either conservative (PaO2 55 to 70 mmHg, or SpO2 88% to 92%) or liberal (PaO2 90 to 105 mmHg, or SpO2 ≥ 96%) oxygen therapy for seven days. […] The available data suggested that mortality at 90 days may be higher in those participants receiving a lower oxygen target (odds ratio (OR) 1.83, 95% confidence interval (CI) 1.03 to 3.27). […] We are very uncertain as to whether a higher or lower oxygen target is more beneficial in patients with ARDS and receiving mechanical ventilation in an intensive care setting. |
32871002 | In addition to abovementioned risk factors, in patients aged between 60-79 years, coronary artery disease, oxygen support need, total number of drugs, and cerebrovascular disease during hospitalization, and in patients 80 years of age and older acute coronary syndrome during hospitalization were also associated with increased risk of mortality. |
32871014 | Data were collected on age, sex, physical ability, rehabilitation modality (remote/direct), need for intubation or extracorporeal membrane oxygenation, degree of pneumonia, oxygen therapy from the start of rehabilitation, D-dimer and C-reactive protein levels, and rehabilitation-related complications. |
32871424 | Demographics (age, gender, smoking status, comorbid conditions, and body-mass index), clinical variables (temperature, oxygen saturation, and symptoms), and laboratory values (white blood cell count, C-reactive protein, D-dimer, and peak interleukin-6) were collected. |
32872310 | The non-invasive estimation of blood oxygen saturation (SpO2) by pulse oximetry is of vital importance clinically, from the detection of sleep apnea to the recent ambulatory monitoring of hypoxemia in the delayed post-infective phase of COVID-19. […] During resting blood oxygen saturation estimation, we found a root mean square difference of 1.47% between the two measurement sites, with a mean difference of 0.23% higher SpO2 in the right ear canal. |
32872607 | A risk tool was developed using a combination of machine learning methods and utilized BMI, temperature, heart rate, respiratory rate, blood pressure, and oxygen saturation. |
32874907 | This has led to questions regarding the most efficacious and least harmful oxygen delivery strategies that minimize exposure to health care workers. […] In this case series, we present the hospital course of 4 patients that were managed with a multi-component oxygen delivery method in a COVID-19 step down unit. |
32874986 | After withdrawal of MV, the patients were transitioned through NIV and high-flow nasal cannula oxygen support. |
32876623 | His respiratory status rapidly worsened to the point of requiring supplemental oxygen by high flow nasal cannula with FiO2 of 80%. […] The patients oxygenation improved significantly over the following days and he was discharged home with no oxygen supplementation and saturating 96% on room air. |
32876689 | The primary outcome, treatment failure on day 21, was defined as death or persistent dependency on mechanical ventilation or high-flow oxygen therapy. |
32878480 | Patients with severe COVID-19 are managed with oxygen support, as are at-risk individuals with chronic lung disease. […] To date, no study has examined whether an increased fraction of inspired oxygen (FiO2) may affect the expression of SARS-CoV-2 entry receptors and co-receptors, including ACE2 and the transmembrane serine proteases TMPRSS1, TMPRSS2, and TMPRSS11D. […] Additionally, SARS-CoV-2 receptor expression was assessed in primary human nasal, tracheal, esophageal, bronchial, and alveolar epithelial cells, as well as primary mouse alveolar type II cells exposed to elevated oxygen concentrations. […] These data highlight the need for further studies that examine the relative contribution of the various viral co-receptors on the infection cycle, and point to oxygen supplementation as a potential risk factor for COVID-19. |
32879035 | Medical-grade oxygen supplies, reliable electricity, bioengineering support, and consumables are all needed for ventilators to save lives. |
32879103 | Among them, laboratory tests included white blood cell (WBC), lymphocytes (LYM), neutrophil (NEU), hemoglobin (Hb), platelet (PLT), prothrombin time (PT), plasma fibrinogen (Fib), activated partial prothrombin time (APTT), thrombin time (TT), D-dimer, total bilirubin (TBIL), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), serum creatinine (Cr), creatine kinase (CK), creatine kinase isoenzyme-MB (CK-MB), lactate dehydrogenase (LDH), C-reactive protein (CRP), and oxygen partial pressure in arterial blood. […] Partial pressure of oxygen in arterial blood/fractional concentration of inspiratory oxygen (PaO2/FiO2) was calculated. |
32879108 | Moreover, for the experimental group, the dynamic changes of blood oxygen saturation before and after the transfusion, the changes of lymphocyte absolute value 48 hours after the transfusion, and the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid were analyzed. […] For the experimental group, before, during and after the convalescent plasma transfusion, the blood oxygen saturation of all 6 patients at all time (1, 6, 8, 12, 24, 36, and 48 h) was more than 90%, and there was no significant fluctuation. |
32880993 | And alveolar-arterial oxygen difference (A-aDO2) and oxygenation index were correlated with IgA and IgG. |
32881304 | The association between baseline CRP, aPTT ratio, PT ratio, D-dimers, fibrinogen, FVIII, VWF:Ag and FVIII/VWF:Ag ratio levels and adverse outcomes (increased oxygen requirements, thrombosis and death at day-30) was assessed by regression analysis after adjustment on age, sex, body mass index, diabetes and hypertension. […] In univariable regression analysis increased CRP (SHR, 1.68; 95%CI, 1.26 to 2.23), increased fibrinogen (SHR, 1.32; 95% CI, 1.04 to 1.68) and decreased FVIII/VWF:Ag ratio (SHR, 0.70 ; 95% CI, 0.52-0.96) levels at admission were significantly associated with the risk of increased oxygen requirement during follow-up. […] Coagulation biomarkers are early and independent predictors of increased oxygen requirement in COVID-19 patients. |
32881350 | Oxygen therapy has been ceased in three patients. […] The time from first tocilizumab administration to improvement in ventilation, defined as a 25% reduction in fraction of inspired oxygen required to maintain peripheral oxygen saturation greater than 92%, ranged from 7 hours to 4.6 days. |
32881359 | There were suggestions of BRH advantage over placebo in improved chest computed tomography, need for oxygen therapy, and discharge rate within 20 days. |
32881982 | As primary outcomes, we studied the evolution of SAFI ratio (oxygen saturation/fraction of inspired oxygen) in the first 48 hours of treatment and the time to discharge. |
32884251 | In addition to video telephony, electrocardiography and assessment of vitals such as pulse, blood pressure, oxygen saturation and auscultation of heart and lungs were applied frequently. |
32884965 | Patient age and initial oxygen requirement, but not race (adjusted proportional odds ratio, 0.92; 95% CI, 0.70-1.20), were associated with worse day 14 outcomes. |
32887660 | The most common treatment options used were hydroxychloroquine (79.7%), ribavirin (65.2%), and oxygen therapy (78.8%). |
32889236 | Improvement after Tocilizumab was defined as improvement in oxygen requirement and inflammatory parameters. […] 29 (77.5%) patients showed significant improvement in oxygen requirement, inflammatory parameters and chest x-rays, out of which 28 patients were discharged home. |
32889638 | Oxygen delivered by ventilators is already in extensive use to provide life support for patients with severe COVID-19. […] Two articles propose to advance the use of oxygen to the level of a therapeutic treatment early in the detection of the virus in infected patients by delivering oxygen under elevated pressure in hyperbaric chambers. […] At elevated blood plasma concentrations, hyperbaric oxygen is capable of achieving results far beyond the capability of ventilators as it promotes the activation of transcription factors that control the establishment of inducible cellular defense systems. |
32892061 | The suggestions for mild (green)category: symptomatic treatment in ward, in moderate (yellow) category: active treatment, semi critical care and oxygen supplementation, in severe (red) category: critical care and intensive care. |
32892893 | Those not in respiratory failure are sent home, often with phone monitoring and/or respiratory rate and oxygen saturation monitoring. |
32893160 | All cases were severe and patients required oxygen administration or had a blood oxygen saturation ≤93% on room air. […] All were treated with favipiravir and methylprednisolone, and 10 of 11 patients responded well and required no further oxygen supplementation or ventilator management. |
32894167 | The artificial manual breathing unit (AMBU) bag connected to wall oxygen source using a flow meter was used as air reservoir. |
32894436 | Twenty-two percent were admitted to the ICU for mechanical ventilation, 11% had non-invasive ventilation or high flow oxygen, and 67% did not have specialist respiratory support. |
32894566 | The degradation of hemoglobin results in the impairment of oxygen-carrying capacity of the blood, and the accumulation of free iron enhances the production of reactive oxygen species. |
32895247 | The use of PP alongside CPAP significantly increased both the ROX index and arterial oxygen pressure:fractional inspired oxygen (PaO2:FiO2) ratio from baseline values (ROX index: 7.0±2.5 baseline vs 11.4±3.7 CPAP+PP, p<0.0001; PaO2:FiO2 ratio: 143±73 mm Hg baseline vs 252±87 mm Hg CPAP+PP, p<0.01), and the changes to both the ROX index and PaO2:FiO2 ratio remained significant 1 hour after cessation of proning. |
32895645 | Key selection criteria included evidence of hyperinflammation, most notably elevated levels of C-reactive protein (CRP) and ferritin, and an increasing oxygen requirement. […] Clinical responses to anti-IL-6/IL-6-R therapy were accompanied by significant decreases in temperature, oxygen requirement, CRP, IL-6, and IL-10 levels. |
32896292 | We enrolled patients admitted to hospital with suspected or confirmed COVID-19 and at least one additional severity criteria as follows: use of oxygen supplementation of more than 4 L/min flow; use of high-flow nasal cannula; use of non-invasive mechanical ventilation; or use of invasive mechanical ventilation. |
32897668 | Data on demography, comorbidities, vital signs, mental status, oxygen saturation, and use of supplemental oxygen at admission to the ward were collected from medical records and used to score National Early Warning Score, National Early Warning Score 2, Rapid Emergency Medicine Score, Confusion, Respiratory rate, Blood pressure, Age 65 score, and quick Sepsis-related Organ Failure Assessment. […] Among the parameters of National Early Warning Score, the oxygen saturation score was found to be the most significant predictor of in-hospital death. […] The area under the receiver operating characteristic (95% CI) for oxygen saturation score was 0.875 (0.834-0.916). […] Peripheral oxygen saturation could independently predict in-hospital death in these patients. |
32897885 | Clinical variables significantly associated with the composite endpoint of non-rebreather or higher oxygen requirement and death (n events = 25/77) included number of co-morbidities (HR 5.41, P = 0.004), infiltrates (HR 3.08, P = 0.032), and neutropenia (HR 1.15, P = 0.04). |
32899009 | At the end of treatment, on day 7, patient reported resolution of fever, normalization of respiratory rate (14 breaths/min), and improved oxygen arterial pressure with a FiO2 of 30%. |
32900168 | She was confirmed as Sars-CoV-2-positive and experienced a steady decrease in oxygen saturation (SaO2), despite being given increasing amounts of supplemental oxygen. |
32900326 | Older age (odds ratio [OR], 1.12; 95% CI, 1.04-1.22; P = 0.004) and hypertension (OR, 6.15; 95% CI, 1.75-29.11; P = 0.009) were associated with mortality, while early improvement in arterial partial pressure of oxygen (PaO2) to fraction of inspired oxygen (FiO2) ratio was associated with being discharged alive from the ICU (P = 0.002 for interaction). |
32900659 | He was admitted to the hospital and started to receive oxygen and favipiravir. |
32900744 | We present a case of a 56-year-old man with COVID-19 who presented to the fever clinic of our institution with fever and cough without any respiratory distress but low oxygen saturation. […] This case demonstrates ‘silent hypoxia’ as a possible presentation in COVID-19 and emphasises the importance of meticulous clinical examination including oxygen saturation measurements in suspected or confirmed patients. |
32905265 | Vital parameters including blood oxygen level, respiratory rate, pulse rate, and body temperature are crucial for triaging patients to appropriate medical care. |
32905897 | Both 2D:4D and the ACE I/D polymorphism are covariates of oxygen metabolism. […] COVID-19 leads to lung damage and a reduction in oxygen saturation of the blood. […] Low 2D:4D and ACE II individuals show efficient oxygen metabolism. |
32907540 | We reported a case of 66-year-old man infected with COVID-19, presenting with fever, cough and myalgia; The patient received supportive and empirical treatment including antiviral treatment, anti-inflammatory treatment, oxygen supply and inhalation therapy; The symptoms, CT images, laboratory results got improved after the treatments, and a throat swab was negative for COVID-19 PCR test; However, on the hospital day 30, the patient presented with a sudden chest pain and dyspnea. |
32907638 | Hospitalised, requiring non-invasive ventilation or high flow oxygen devices; 4. […] Hospitalised, requiring supplemental oxygen; 5. […] Hospitalised, not requiring supplemental oxygen - but in need of ongoing medical care (COVID-19 related or otherwise) 6. […] Hospitalised, not requiring supplemental oxygen - no longer requires ongoing medical care (independent) 7. |
32907855 | The final 4C Mortality Score included eight variables readily available at initial hospital assessment: age, sex, number of comorbidities, respiratory rate, peripheral oxygen saturation, level of consciousness, urea level, and C reactive protein (score range 0-21 points). |
32907873 | A 71-year-old man presented to the emergency department (ED) with low oxygen saturations and symptoms consistent with COVID-19 infection. |
32907890 | Among all (n=349) patients hospitalised for COVID-19 in a university hospital in a French region with a high rate of COVID-19, we analysed patients who underwent CTPA for clinical signs of severe disease (oxygen saturation measured by pulse oximetry ≤93% or breathing rate ≥30 breaths·min-1) or rapid clinical worsening. |
32908046 | Furthermore, the median duration from oxygen therapy initiation to death or intubation was significantly shorter in the patients with hematological disease (5 days [range, 1-17 days] vs. 10 days [1-24 days], respectively; P<0.05). |
32908840 | Symptomatic treatment with oxygen supplementation and pulmonary physical therapy was initiated, and hydroxyurea was discontinued. […] Over 14 days, the patient’s blood counts slowly recovered, and his clinical condition gradually improved, such that supplemental oxygen was no longer necessary and he could be discharged. |
32909713 | Methemoglobin impairs hemoglobin’s ability to transport oxygen, produces functional anemia, and leads to tissue hypoxia. |
32910106 | Data from debriefings and observations demonstrated the following categories of latent safety threats: inadequate preparedness on infection control, uncertainty of guidelines on oxygen supplementation and intubation protocols, lack of leadership and communication, overall panic, and others. |
32911986 | The patient was discharged home after 47 days of hospitalization without any supplemental oxygen and was able to undergo active physical rehabilitation. |
32912049 | High flow nasal cannula (HFNC) is a widely used modality of delivering high concentrations of oxygen and airflow to patients with hypoxemic respiratory failure, but its use in patients with SARS-CoV-2 is poorly described. |
32912329 | Our patient was a 27-year-old Caucasian woman with a past medical history of asthma transferred from a community hospital to our medical intensive care unit for acute hypoxic respiratory failure due to bilateral pneumonia requiring mechanical ventilation (ratio of arterial oxygen partial pressure to fraction of inspired oxygen, 180). |
32912961 | SARS-CoV-2 infection has been associated with the development of cytokine storm (including interleukin 6 (IL-6)), which can cause lung damage and lack of oxygen. […] Respiratory rate and oxygen supplementation as well as laboratory parameters (such as C-reactive protein (CRP), aspartate aminotransferase and alanine aminotransferase) were collected at baseline and during 14 days of follow-up. […] In each group, 10 patients no longer required oxygen therapy. […] The same number of patients were weaned off oxygen on day 14 in the two groups, while the patients in the TCZ group had more severe impairment at inclusion. |
32913866 | The patient was treated with supplementary oxygen by nasal cannula and gamma globulin. |
32918548 | For children with severe illness, defined as a supplemental oxygen requirement without need for non-invasive or invasive mechanical ventilation or extra-corporeal membrane oxygenation (ECMO), remdesivir is suggested, preferably as part of a clinical trial if available. |
32918761 | Eligible patients were hospitalized and required to have positive nasopharyngeal polymerase chain reaction (PCR) diagnosis of SARS-CoV-2 infection, be at least 18 years old, and have either dyspnea, blood oxygen saturation ≤ 93% on ambient air, respiratory frequency ≥ 30 breaths/min, partial pressure of arterial oxygen to fraction of inspired oxygen ratio < 300, or lung infiltrates > 50%. |
32920232 | NI/I-VS was defined as the need for continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BPAP) (non-invasive ventilation) or mechanical ventilation, not including low-flow systems of oxygen therapy such as the Venturi mask or nasal cannula. […] Thirty-five of the 97 patients (36%) required ICU admission and 94.8% (92/97) were prescribed oxygen therapy: 10.8% (10/92) by nasal cannula, 44.5% (41/92) by Venturi mask, 31.5% (29/92) by CPAP, 2.2% (2/92) by BPAP, and 10.8% (10/92) by mechanical ventilation following intubation. |
32921708 | They had significantly higher systolic and diastolic blood pressures, longer duration of hospitalization, ICU stay, mechanical ventilation and oxygen therapy. […] CRP was correlated significantly with the duration of stay in the ICU and the duration for oxygen supplementation (r = 0.37 and 0.42 respectively; p: <0.01). […] Diabetic patients had more comorbidities and more aggressive course of the disease with higher rate of ICU admission and longer need for hospitalization and oxygen use. |
32922210 | These three ‘Recovery’ RCTs concluded definitely: (a) that treatment with hydroxychloroquine provides no benefits in patients hospitalized with COVID-19; (b) that treatment with dexamethasone reduced deaths by one-third in COVID-19 patients that were mechanically ventilated, and by one-fifth in patients receiving oxygen only; (c) that the combination of Lopinavir and Ritonavir is not effective in reducing mortality in COVID-19 hospitalized patients. |
32922409 | Patients with evidence of progressive disease after 24 h including an oxygen saturation <93% at rest in ambient air were included at the University Hospital Basel, Switzerland in April 2020.

32922804 | We followed clinical improvement in the radiological analysis (two of three cases), oxygen saturation (Spo2), respiratory rate, disappearance of dyspnoea, coughing and a decrease in NET formation and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load after the treatment. |
32923016 | The primary outcome was set as the time to clinical improvement, defined as normalization of body temperature, respiratory rate, oxygen saturation, cough, and absorption of pulmonary infection by chest computed tomography (CT) until 28 d after randomization. |
32924219 | Herein it is a therapeutic based on catalase, an antioxidant enzyme that can effectively breakdown hydrogen peroxide and minimize the downstream reactive oxygen species, which are excessively produced resulting from the infection and inflammatory process, is reported. |
32925581 | The median period from the non-invasive mechanic ventilation (NIV) or high-flow nasal cannula oxygen therapy (HFNC) to intubation was 7 hours (IQR 2-42) in IMV survivors and 54 hours (IQR 28-143) in IMV non-survivors. |
32926678 | His initial oxygen saturation registered at SpO2 (blood oxygenation saturation) 55% on room air. |
32926931 | A negative correlation with tissue oxygen consumption (delta pO2) and compartmental fluid shift was seen in Group 1 only. |
32927092 | To evaluate the efficacy and safety of a new treatment for COVID-19 vs. standard care, certain key endpoints are related to the duration of a specific event, such as hospitalization, ICU stay, or receipt of supplemental oxygen. […] For the analysis of ICU stay or oxygen usage, where the initiating event is potentially an outcome of treatment, standard survival analysis techniques may not be appropriate. |
32928122 | Secondary endpoints include the number of attempts at intubation, lowest oxygen saturation during induction, and the need for bag-mask ventilation. |
32928157 | At ICU admission the patient had fever and severe acute respiratory failure requiring high flow oxygen therapy. |
32928319 | Decreased oxygen saturation at admission was associated with increased odds of mortality (OR, 1.09; 95% CI, 1.06-1.12; P < .001) as was diabetes (OR, 1.57; 95% CI, 1.21-2.03; P < .001). |
32928787 | This single-centre retrospective study aimed to assess whether successful awake proning of patients with COVID-19, requiring respiratory support (continuous positive airways pressure (CPAP) or high-flow nasal oxygen (HFNO)) on a respiratory high-dependency unit (HDU), is associated with improved outcomes. |
32930099 | Of 2634 patients who died of COVID-19, 1478 (56.1%) had oxygen saturation levels ≥90% on presentation and required no respiratory support. […] Before the RRT/CA call, the most recent oxygen saturation levels for 852/1112 (76.6%) of these non-ICU patients were at least 90%. […] At the time the RRT/CA was called, 479/1112 patients (43.1%) had an oxygen saturation of <80%. […] Patients admitted at a non-ICU level of care suffered rapid clinical deterioration, often with a sudden decrease in oxygen saturation. |
32931666 | Given the high mortality and prolonged duration of mechanical ventilation of COVID-19 patients, we evaluated the safety and efficacy of hyperbaric oxygen for COVID-19 patients with respiratory distress. […] Patients in this trial received hyperbaric oxygen therapy at 2.0 atmospheres of pressure in monoplace hyperbaric chambers for 90 minutes daily for a maximum of five total treatments. […] We treated 20 COVID-19 patients with hyperbaric oxygen. […] Ages ranged from 30 to 79 years with an oxygen requirement ranging from 2 to 15 liters on hospital days 0 to 14. […] Among 60 propensity-matched controls based on age, sex, body mass index, coronary artery disease, troponin, D-dimer, hospital day, and oxygen requirement, 18 (30%) were intubated, 13 (22%) have died, and three (5%) remain hospitalized (with one still requiring mechanical ventilation). […] Though limited by its study design, our results demonstrate the safety of hyperbaric oxygen among COVID-19 patients and strongly suggests the need for a well-designed, multicenter randomized control trial. |
32932327 | The remaining patients, with late infection, were all discharged home without oxygen support, at a median of 25 days after symptom onset. |
32932329 | Oxygen administration (41%) and noninvasive ventilation (16%) were frequently required; however, mechanical ventilation (3%) was rarely needed. […] C-reactive protein (CRP) and prothrombin time (PT) levels were found to be higher in patients who needed supplemental oxygen (0.9 [0.1-8.6] vs. |
32932951 | The main COVID-19 symptoms included benign upper respiratory infection signs (N = 9, 81.8%), diarrhea (N = 7, 63.6%), fatigue (N = 7, 63.6%), and respiratory signs (N = 5, 45.5%), including one patient who needed oxygen therapy. |
32933914 | We saw a reduction in oxygen requirement and improvements in inflammatory markers and ferritin. |
32934000 | Composite poor outcomes include intensive care unit admission, oxygen saturation <90%, invasive mechanical ventilation utilisation, severe disease, in-hospital admission and mortality. |
32934372 | Oxygen requirements on day 14 after transfusion worsened in 17.9% of plasma recipients versus 28.2% of propensity score-matched controls who were hospitalized with COVID-19 (adjusted odds ratio (OR), 0.86; 95% confidence interval (CI), 0.75-0.98; chi-square test P value = 0.025). |
32934903 | The patient had no predisposing risk factors for pneumothorax, such as a history of trauma, smoking, past intubations, asthma, high pressure oxygen delivery, or a history of prior pneumothorax. |
32935329 | Patients receiving IMV were characterized by a moderately decreased median [IQR] partial pressure of oxygen:fraction of inspired oxygen (day 1 PaO2:FiO2 = 177 [138-276]; day 10 = 173 [147-227]) and compliance (day 1 = 48 [38-58] mL/cmH2O; day 10 = 34 [28-42] mL/cmH2O) and very elevated estimated dead space fraction (day 1 = 0.60 [0.53-0.67]; day 10 = 0.72 [0.69-0.79]). |
32935808 | Patients with room air oxygen saturation < 90% were considered as severe COVID-19, and patients with ≥90% were considered moderate COVID-19. […] According to oxygen saturation, 81 patients had moderate and 134 had severe COVID-19. […] Our findings revealed that oxygen saturation at admission and the MPV difference between the first and third days of hospitalization were significant parameters in COVID-19 patients for predicting mortality. […] While mortality was 8.4 times higher in patients who had oxygen saturation under 90 % at hospital admission, 1 unit increase in MPV increased mortality 1.76 times. |
32935928 | SARS-CoV-2 can cause CVD by inducing cytokine storms, creating an imbalance in the oxygen supply and demand and disrupting the renin-angiotensin-aldosterone system; SARS-CoV-2 infection can also lead to the development of CVD through the side effects of therapeutic drugs, psychological factors, and aggravation of underlying CVD. |
32936491 | The total LS showed a strong correlation (r = -0.765) with the oxygen pressure-to-fraction of inspired oxygen ratio; by lung region, those with a higher correlation were the LS of the anterior region (r = -0.823) and the LS of the upper region (r = -0.731). |
32937800 | Secondary endpoints included favorable change in the Ordinal Scale for Clinical Improvement on days 14 and 28 versus baseline, proportion of patients not requiring supplemental oxygen on days 14 and 28, and proportion of patients discharged by day 28. |

[…] Patients must present elevation of inflammatory parameters (IL-6 > 40 pg/mL or d-dimer >1.0 mcg/ml) or, alternatively, progressive worsening in at least two of these inflammatory parameters in the prior 24-48h: CRP, LDH, serum ferritin, lymphopenia, or d-dimer. high oxygen requirements (including face mask with reservoir, non-invasive mechanical ventilation or high flow nasal cannula, or mechanical ventilation), admission to ICU, pregnancy or lactation, allergy or hypersensitivity to sarilumab or corticoesteroids, immunosuppressive antibody therapy within the past 5 months, AST/ALT values > 10 x ULN, neutropenia (< 0.5 x 109/L), severe thrombocytopenia (< 50 x 109/L), sepsis caused by an alternative pathogen, diverticulitis with risk of perforation or ongoing infectious dermatitis. |
32938758 | Risk factors for COVID-19 patients with poorer outcomes include pre-existing conditions: obesity, type 2 diabetes mellitus, cardiovascular disease (CVD), heart failure, hypertension, low oxygen saturation capacity, cancer, elevated: ferritin, C reactive protein (CRP) and D-dimer. […] Hyperinsulinaemia mediates thrombi development via: fibrinolysis inhibition, anticoagulation production dysregulation, increasing reactive oxygen species, decreased antioxidant capacity via nicotinamide adenine dinucleotide depletion, haem oxidation and catabolism, producing carbon monoxide, increasing deep vein thrombosis risk and pulmonary emboli. […] Increased haem-synthesis demand upregulates carbon dioxide production, decreasing oxygen saturation capacity. |
32938838 | During the first week after tracheal intubation, non-survivors displayed lower values for minimum ratio of the partial pressure of oxygen to fractional inspiratory oxygen concentration (P/F ratio) (44 mmHg vs. 122 mmHg, p < 0.01) and poor response to intensive therapy compared with survivors. |
32943538 | Logistic regression showed increasing odds of respiratory failure with sC5b-9 (odds ratio 31.9, 95% CI 1.4 to 746, P = 0.03) and need for oxygen therapy with C4d (11.7, 1.1 to 130, P = 0.045). |
32943872 | Specifically, through an inter-professional and collaborative approach to care delivery, we provide rationale and guidance on prone positioning, oxygen strategies, early mobilization, identifying and treating co-infections, anticoagulation and ensuring appropriate psychological support for patients and their families. |
32945149 | Oxygen requirements and clinical outcomes of interests were captured as well as laboratory parameters at baseline and 3 days after treatment. |
32945644 | Pneumothorax, pneumomediastinum, bronchiectasis and cysts are probably underrated complications of COVID-19 that can worsen prognosis, in terms of prolonged hospitalization and need of oxygen therapy. |
32945710 | Approximately 14% of UK hospital in-patients receive supplemental oxygen therapy, only 57% have valid prescriptions. […] Oxygen must be optimally prescribed to ensure maximal therapeutic response whilst minimizing adverse outcomes (including fatality). […] Of the 636 patients admitted, 66 (10%) were receiving oxygen therapy. […] The prescription was not documented in the oxygen section of the drug chart (n = 37, 56.1%, p = 0.389), nor did it have the physicians signature (n = 40, 60.6%, p = 0.110) nor date (n = 46, 69.7%, p = 0.002). […] Target oxygen saturation (SpO2) range had been documented for 30 (45.5%) patients. |
32946668 | Among patients who received tocilizumab, there was also no difference in mortality based on the level of oxygen support (intubated vs not intubated) at the time of tocilizumab initiation. |
32947292 | The ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2) significantly increased during PP (change from baseline and CI 97.5%: 110 [19; 202]) and after PP, albeit not significantly (change from baseline and CI 97.5%: 38 [-9.2; 85]) compared with previous supine position. |
32947927 | The proposed pathophysiological mechanisms of myocardial impairment include invasion of SARS-CoV-2 virus via angiotensin-converting enzyme 2 to cardiovascular cells/tissue, which leads to endothelial inflammation and dysfunction, de-stabilization of vulnerable atherosclerotic plaques, stent thrombosis, cardiac stress due to diminish oxygen supply and cardiac muscle damage, and myocardial infarction. |
32948531 | This case suggests that a high index of suspicion should be taken into consideration for thromboembolic events, when treating patients with COVID-19 with breathing difficulty and low oxygen saturation levels, especially in those who have underlying predisposing conditions for coagulopathy. |
32949098 | No patient required supplemental oxygen, intubation, or ECMO. |
32949777 | Hospitalization rate was 11.6%, 1.3% required supplemental oxygen, 0.6% needed intensive care unit admission, and 0.3% required mechanical ventilation. |
32950458 | Rapid deterioration of these cases with septic shock, accompanying with lung CT images enlarged rapidly, decrease of blood oxygen, heart rate drop (with asynchrony of hypoxemia) accompanied with SARS-CoV-2 viremia. |
32951346 | Cavalli et al. defined severe respiratory distress as partial pressure of oxygen in arterial blood to the fractional concentration of oxygen in inspired air ≤ 100 mmHg in the setting of bilateral pulmonary infiltrates and a positive end-expiratory pressure ≥ 5 cm H2 O. |
32952981 | None of the patients required oxygen supplementation nor mechanical ventilation. |
32953091 | Results: Compared with the baseline, treatment contributed to and exacerbated the deterioration of pulmonary pathology by reducing lung compliance and the arterial oxygen partial pressure to fractional inspired oxygen (PaO 2/FiO 2) ratio. […] The oxygen extraction index changes mirrored those of the PaO 2/FiO 2 ratio. |
32953947 | Analysis of existing data revealed that HA natives do possess certain physiological advantages such as (1) improved hypoxic ventilatory response, (2) higher concentration of oxygen carrying molecules, haemoglobin, (3) increased production of Vitamin D, due to intense solar radiation, (4) lower rates of comorbidities such as lung infections, obesity etc. and (5) most importantly reduced production of angiotensin converting enzyme 2, a carrier molecule for SARS-CoV-2 virus entry into the host cell; all of which can collectively account for improved tolerance to SARS-CoV-2 infection in HA natives. |
32953968 | Multivariate logistic regression analysis revealed that obesity (OR 2.029, 95% CI 1.039-3.961; p = 0.038), arterial oxygen saturation <90% (OR 2.250, 95% CI 1.216-3.560; p = 0.025), and systolic blood pressure <90 mmHg (OR 2.636, 95% CI 1.530-4.343; p = 0.042), were directly related to higher levels of troponins. |
32958495 | DisCoVeRy is a phase III, open-label, adaptive, controlled, multicentre clinical trial in which hospitalised patients with COVID-19 in need of oxygen therapy are randomised between five arms: (1) a control group managed with SoC and four therapeutic arms with re-purposed antiviral agents: (2) remdesivir + SoC, (3) lopinavir/ritonavir + SoC, (4) lopinavir/ritonavir associated with interferon (IFN)-β-1a + SoC and (5) hydroxychloroquine + SoC. |
32959547 | Demographic and epidemiological information, comorbidities, clinical signs and symptoms, laboratory and radiologic findings, medications, treatments, outcomes, and main durations of patients with COVID-19 were compared according to supplemental oxygen requirement. […] Six (15%) patients required supplemental oxygen. […] Sputum production, chest discomfort, a large number of symptoms, abnormal procalcitonin and C-reactive protein levels, and abnormal chest X-ray or chest computed tomography findings were more common in patients requiring supplemental oxygen than in those not requiring supplemental oxygen. |
32959951 | There are numerous proposed mechanisms of cardiac injury, including direct cellular injury, pro-inflammatory cytokine storm, myocardial oxygen-demand mismatch, and systemic inflammation causing multi-organ failure. |
32962092 | We noted a less severe clinical presentation in the PCR- group (lower respiratory rate, lower oxygen need and mechanical ventilation requirement). |
32963432 | The most common reason for ICU admission in our series of 24 patients with severe COVID-19 was hypoxemic respiratory failure, which responded well to conservative measures such as awake proning and oxygen supplementation. |
32963439 | Noninvasive ventilation (NIV), high-flow oxygen via nasal cannula, supplementary oxygen with venturi face mask, or nasal cannula were used variedly in these patients. […] Mechanical ventilatory support is offered to patients with AHRF when other methods, such as NIV and oxygen via high-flow nasal cannula, fail. |
32964179 | All four patients showed evidence of deterioration, with hyperferritinaemia and increasing oxygen requirements and with superadded bacterial infections. |
32964483 | This association remained significant after correction for age (OR = 1.16, 95%CI 1.01-1.34, P = .029 for RV free wall LS and OR = 1.20, 95%CI 1.01-1.42, P = .033 for RV-GLS), for oxygen partial pressure at arterial gas analysis/fraction of inspired oxygen (OR = 1.28, 95%CI 1.04-1.57, P = .021 for RV free wall-LS and OR = 1.30, 95%CI 1.04-1.62, P = .020 for RV-GLS) and for the severity of pulmonary involvement measured by a computed tomography lung score (OR = 1.27, 95%CI 1.02-1.19, P = .034 for RV free wall LS and OR = 1.30, 95%CI 1.04-1.63, P = .022 for RV-GLS). |
32966582 | RNA sequencing confirmed a transcriptional response to viral infection as demonstrated by the up-regulation of genes associated with pathways related to viral response and interferon signalling, apoptosis, and reactive oxygen stress. |
32967165 | CQ/HCQ-induced alterations in proton fluxes influence the type and chemical reactivity of reactive oxygen species (ROS). |
32969531 | Heart rate, respiratory rate, blood pressure, oxygen saturation, and time to exhaustion did not differ significantly. |
32970246 | In multivariable analysis, older age, admission respiratory status including elevated respiratory rate and oxygen saturation ≤ 88%, and initial laboratory derangements of creatinine > 1.33 mg/dL, alanine aminotransferase > 40 U/L, procalcitonin > 0.5 ng/mL, and lactic acid ≥ 2 mmol/L increased risk of in-hospital death. […] Older age, low oxygen saturation and elevated respiratory rate on admission, and initial lab derangements including renal and hepatic dysfunction and elevated procalcitonin and lactic acid are risk factors for in-hospital death. |
32970733 | A two-factor logistic model using patient age and oxygen saturation was created, which demonstrates 89% accuracy and area under the ROC curve of 0.86 (p<0.0001). |
32971109 | Our major findings were as follows: (1) severe clinical outcome (ICU treatment) was associated with high plasma levels of sTIM-3 and myeloperoxidase, suggesting activated and potentially exhausted T cells and activated neutrophils, respectively; (2) in contrast, sCD14 and sCD163 showed no association with need for ICU treatment; and (3) levels of sCD25, sTIM-3, and myeloperoxidase were inversely correlated with degree of respiratory failure, as assessed by the ratio of Pao2 to fraction of inspired oxygen, and were positively correlated with the cardiac marker N-terminal pro-B-type natriuretic peptide. |
32971254 | We included consecutive adult patients with severe COVID-19, defined as respiratory rate ≥30 breath per minute, oxygen saturation ≤93% on ambient air or arterial partial pressure of oxygen to fraction of inspired oxygen ≤300 mm Hg. |
32972411 | The authors review well-known mechanisms that contribute to development of hypoxemia in patients with pneumonia, but are less clear as to why patients should be free of respiratory discomfort despite arterial oxygen levels commonly regarded as life threatening. |
32972430 | Clinical improvement, negative conversion of reverse transcription-polymerase chain reaction (RT-PCR), adverse effects, and oxygen requirements were studied. […] The meta-analysis showed no significant differences between the two groups on viral clearance (day 14: RR 1.06, 95% CI 0.84-1.33), non-invasive ventilation or oxygen requirement (OR 0.76, 95% CI 0.42-1.39), and adverse effects (OR 0.69, 0.13-3.57). […] There is a significant clinical and radiological improvement following treatment with FVP in comparison to the standard of care with no significant differences on viral clearance, oxygen support requirement and side effect profiles. |
32974111 | In contrast, among younger people, men had higher odds of severe pneumonia, need for high oxygen support, acute kidney injury and acute liver injury when compared to women. |
32975205 | At logistic regression analysis, gestational age at diagnosis (OR: 0.85, 95% CI 0.8-0.9 per week increase; p<0.001), birthweight (OR: 1.17, 95% CI 1.09-1.12.7 per 100 g decrease; p=0.012) and maternal ventilatory support, including either need for oxygen or CPAP (OR: 4.12, 95% CI 2.3-7.9; p=0.001) were independently associated with composite adverse fetal outcome. |
32975814 | Adverse outcomes defined as intensive care units, oxygen saturation less than 90%, invasive mechanical ventilation, severe disease, and in-hospital mortality. |
32976364 | Overall, one-third of patients had an oxygen saturation of bellow 90% on admission. |
32977101 | Arterial blood gas analysis showed low pO2, pCO2, and ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2) indicating hypocapnic hypoxemia. |
32977137 | We evaluated the gas exchange over time through the ratio of partial pressure of arterial oxygen (PaO2) to the fraction of inspired oxygen (FiO2) at baseline, 7, and 14 days after randomization, the time until successful liberation from mechanical ventilation, and the ventilator-free days. |
32977606 | Our final model identified nine key features: age, oxygen saturation, smoking, serum creatinine, lymphocytes, hemoglobin, platelets, C-reactive protein, and sodium at admission. |
32978307 | The most discriminating univariable predictors were admission oxygen saturation on room air for in-hospital deterioration (AUROC 0.76; 0.71-0.81), and age for in-hospital mortality (AUROC 0.76; 0.71-0.81). […] Admission oxygen saturation on room air and patient age are strong predictors of deterioration and mortality among hospitalised adults with COVID-19, respectively. |
32978920 | This retrospective study was undertaken to explore the physiotherapy practices that could be implemented in patients admitted with COVID 19 in the ICU and its effect on mobility and oxygen requirement as an outcome. […] Demographic characteristics, disease severity, oxygen requirement, mobility status, physiotherapy intervention were studied. 278 record sheets (110 ICU and 168 SDU) were retrospectively analysed for demographics. […] Descriptive analysis showed a definitive reduction in oxygen support requirement. |
32978927 | Most can be managed with home isolation under telemedicine supervision with oxygen saturation screening by a simple six minute walk test. […] Hospitalised cases have emerging evidence in different therapies from antivirals, steroids, immunologic to heparins but high flow oxygen, prone position and supportive care remains the cornerstone in critical care with nursing and nutrition. |
32979425 | Laboratory results including myocardial biomarkers, oxygen saturation, inflammatory indicators and coagulation function were compared between survivors and non-survivors. |
32980424 | Ten were asymptomatic, 25 were treated as outpatients, 28 required admission without intensive care or ventilation, 13 required non-invasive ventilation or oxygen administration, 18 were admitted to intensive care units, 12 requiring invasive ventilation, and 3 extra corporeal membrane oxygenation. |
32980556 | Six patients with SCD had COVID-19 (1.6%): three remained asymptomatic, two had mild symptoms and one required oxygen therapy. |
32981508 | Oxygen transport physiology, SARSCov-2 characteristics, and its transmission, lung imaging in COVID-19, and HAPE, as well as the causes of clinical signs and symptoms, are discussed. […] High-altitude oxygen transport physiology has been systematically ignored. […] COVID-19 signs and symptoms indicate a progressive and irreversible failure in the oxygen transport system, secondary to pneumolysis produced by SARS-Cov-2’s alveolar-capillary membrane “attack”. |
32983456 | High-flow nasal cannula oxygen therapy (HFNC) has been shown to be a useful therapy in the treatment of patients with Acute Respiratory Distress Syndrome (ARDS), but its efficacy is still unknown in patients with COVID-19. |
32984400 | Proteolytic knockdown of GPX1 is highly consistent with previously documented effects of recombinant SARS-CoV Mpro in transfected cells, including increased reactive oxygen species and NF-κB activation. |
32984797 | This model was based on three clinical features: patient’s age, minimum oxygen saturation over the course of their medical encounter, and type of patient encounter (inpatient vs outpatient and telehealth visits). |
32984838 | Among 948 patients, 122 (12.87%) received invasive ventilation, 637 (67.19%) received supplemental oxygen only, and 189 (19.94%) received no respiratory support. […] The rate of in-hospital death for invasive ventilation recipients was 22.95%, 12.87% for supplemental oxygen recipients, and 7.41% for those who received neither (p = 0.0004). […] A sensitivity analysis of the 770 patients less than 80 years old revealed a lower, but similar mortality trend (18.02%, 8.10%, 5.23%; p = 0.0008) among the 14.42%, 65.71%, and 19.87% of patients treated with mechanical ventilation, supplemental oxygen only, or neither. |
32985211 | In addition, Resveratrol was demonstrated to be a stimulator of fetal hemoglobin and a potent antioxidant, by trapping reactive oxygen species (ROS). |
32986274 | Eligible patients were hospitalized, had radiographic consolidation, required supplemental oxygen, and were clinically deteriorating. […] Within 24 hours of radiation, 3 patients (60%) were weaned from supplemental oxygen to ambient air, 4 (80%) exhibited radiographic improvement, and the median Glasgow Coma Scale score improved from 10 to 14. […] A fourth patient (80% overall recovery) was weaned from oxygen at hour 96. […] In a pilot trial of 5 oxygen-dependent elderly patients with COVID-19 pneumonia, low-dose whole-lung radiation led to rapid improvements in clinical status, encephalopathy, and radiographic consolidation without acute toxicity. […] Each had pneumonia visible on a chest x-ray, required supplemental oxygen, and experienced a clinical decline in mental status or in work of breathing or a prolonged or escalating supplemental oxygen requirement. |
32986793 | The respiratory support during hospitalization includes those who received no oxygen support (61.6%, 1623/2636), followed by those who received supplemental oxygen (29.9%, 788/2636), and IMV/ECMO (mechanical ventilation or extracorporeal membrane oxygenation) (8.5%, 225/2636). |
32986989 | The primary outcomes included (1) a composite of adverse maternal outcome, defined as preeclampsia, venous thromboembolism, antepartum admission, maternal intensive care unit admission, need for mechanical ventilation, supplemental oxygen, or maternal death, and (2) a composite of adverse neonatal outcome, defined as respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, 5-minute Apgar score of <5, persistent category 2 fetal heart rate tracing despite intrauterine resuscitation, or neonatal death. |
32987177 | Logistic regression analysis was conducted to evaluate the adjusted odds of survival for patients receiving oxygen therapy or convalescent plasma, based on therapeutic effectiveness observed for other respiratory illnesses. […] After adjustment for sex, age, and underlying conditions in the synthetic case population, the odds of mortality for cases not receiving oxygen therapy was significantly higher than those receiving oxygen, such as due to disruptions to standard care (OR: 2.07; 95% CI: 1.56 - 2.75). […] Investment in sustainable production and maintenance of supplies for oxygen therapy, along with messaging around early and appropriate use for healthcare providers, caregivers, and patients could reduce COVID-19 deaths in SSA. |
32987701 | Mitochondria are the main source of reactive oxygen species (ROS), most of them deriving from the mitochondrial respiratory chain. |
32990580 | With ASD closed, the atrial shunts disappeared, the peripheral artery pressure of oxygen(PaO2): 141.2±21.4mmHg, the oxygenation index (PaO2/FiO2): 353.0±53.5, the mean blood pressure (MAP): 49.3±13.5 mmHg, the heart was full; with ASD opened, the left-to-right shunt was observed, PaO2: 169.3±18.9mmHg, PaO2/FiO2: 423.3±47.3, MAP: 68.2±16.1 mmHg, the range of cardiac motion significantly increased, heart beat was powerful, and systemic circulation significantly improved. |
32992843 | We found: (i) In SP-A2 mice, the redox alteration of AM in response to O3 showed sex-dependence with AM from males being significantly more oxidized and having a higher level of mitochondrial reactive oxygen species than females; (ii) AM from KO mice were more oxidized after O3 exposure and showed no sex differences; (iii) AM from female KO mice were more oxidized than female SP-A2 mice; and (iv) Two distinct subpopulations characterized by size and redox status were observed in a mouse AM sample. |
32992875 | For example, a viral infection can switch energy metabolism from respiration to widely anaerobic glycolysis even if plenty of oxygen is available (the Warburg effect) when the host cell cannot generate acetyl-coenzyme A, a metabolite required for melatonin biosynthesis. |
32993451 | Paired analysis of the partial pressure of arterial oxygen(PaO2): fraction of inspired oxygen(FiO2) ratio (PF ratio) (n = 89) and FiO2 (n = 129) was recorded within 3 hours of both the initiation and termination of PP and differences were assessed with the paired Student’s t-test and Wilcoxon Signed-Rank test. […] In summary, PP improved arterial oxygenation and reduced oxygen requirements in most Covid-19 patients in this single- center, retrospective analysis. |
32993479 | The fraction of inspired oxygen requirements was reduced for all five patients after initiating dornase alfa administration. |
32994187 | All patients had pneumonia and exhibited oxygen saturation <95% when breathing ambient air or when receiving oxygen support. |
32997237 | The following variables were extracted for this study: age, gender, temperature, and saturation of oxygen on admission, treatment with hydroxychloroquine, azithromycin, heparin, steroids, tocilizumab, a combination of lopinavir with ritonavir, and oseltamivir, together with data on mortality. […] This association remained significant when saturation of oxygen < 90% and temperature > 37 °C were added to de model with OR 0.45 (0.30-0.68) p < 0.001, and also when all the other drugs, and time of admission, were included as covariates. |
32999777 | Overall, 39% of the subjects did not need respiratory support, while 13% were on a ventilator, 16% on bilevel positive airway pressure/continuous positive airway pressure (BiPAP/CPAP), and 31% on supplemental oxygen therapy. |
33000107 | Inflammatory markers such as C-reactive protein, D-dimer, ferritin, fibrin degradation product and interleukin-6 were significantly elevated (P <0.05) in patients who required oxygen therapy than those who did not require it, suggesting the potential role such markers could play in predicting prognosis in patients. |
33003134 | Men were more likely to receive oxygen therapy (144 [6.46%] vs 131 [4.63%], P = 0.004), be admitted to the intensive care unit (60 [2.69%] vs 53 [1.87%], P = 0.049), and have a longer length of stay after admission to the intensive care unit (19.70 ± 11.80 vs 14.75 ± 9.23, P = 0.016). |
33004712 | Ozone therapy consists in the administration of a mixture of ozone and oxygen, called medical ozone, which has been used for over a century as an unconventional medicine practice for several diseases. |
33005276 | The proportion of patients received oxygen therapy was 22.7% in the asymptomatic group and 99.1% in symptomatic patients (p < 0.001). |
33005428 | On day 23, lung opacity on the chest X-ray cleared and the patient’s oxygen saturation improved significantly. |
33005518 | Phosphorus levels remained elevated, and sevelamer was added on discharge after he was weaned off oxygen and cleared by physical therapy. |
33006317 | Among patients that were almost 100% certain which person infected them, only 14 out of 38 overall, and 9 out of 25 hospitalized patients requiring supplemental oxygen, were infected by someone who coughed, which did not support our hypothesis. |
33006440 | High-sensitivity cardiac troponin I levels were significantly associated with neutrophil/lymphocyte ratio, creatinine, d-dimer, lactate dehydrogenase, and inflammatory cytokines and negatively associated with oxygen saturation. |
33007478 | When patients received corticosteroids before they required nasal high-flow oxygen therapy or mechanical ventilation, the in-hospital death rate was lower than that in patients who were not administered corticosteroids (17/86, 19.8% vs. |
33008453 | She received steroids, anticoagulation, and convalescent plasma, and within 48 h she was off oxygen. |
33010257 | Multivariable logistic and linear regressions, and survival analysis were performed depending on outcomes: need for IMV, evolution of arterial oxygen tension/fraction of inspired oxygen ratio (PaO2/FiO2) or mortality. |
33011717 | The Cox proportional hazard model after adjusting for age, gender, comorbidities, hemodynamic status, and PF ratio (arterial oxygen partial pressure [PaO2]/fractional inspired oxygen [FiO2]) determined that on admission, an elevated blood urea nitrogen (hazard ratio [HR]: 1.75; 95% confidence interval [CI] 1.23-2.48), a low eGFR (HR 1.43; CI 1.1-2.03), AKI stage 1 (HR 1.14; CI 0.64-2.03), AKI stage 2 (HR 1.86; CI 1.03-3.56), and AKI stage 3 (HR 2.1; CI 1.3-2.81) were independent risk factors for in-hospital mortality. |
33012378 | This was an observational, retrospective, cohort study from a 9-ED health system of admitted adult patients with severe acute respiratory syndrome coronavirus 2 (COVID-19) and an oxygen requirement less than or equal to 6 L/min. […] We sought to predict respiratory failure within 24 hours of admission as defined by oxygen requirement of greater than 10 L/min by low-flow device, high-flow device, noninvasive or invasive ventilation, or death. |
33012857 | The COVID 19 pandemic is exposing an important weakness in health systems: medical oxygen production and delivery. |
33014275 | During a virus-induced cytokine storm, metabolic flexibility is compromised due to increased levels of reactive oxygen species (ROS) and reactive nitrogen species (RNS) that damage, downregulate, or inactivate many enzymes of central metabolism including the pyruvate dehydrogenase complex (PDC). |
33014499 | Treatment provided to the child included intranasal oxygen, antibiotics, and a dietary program with therapeutic milk. |
33014697 | We should note that, respiration process is the movement of oxygen from external atmosphere to the cells within tissue and the transport of carbon dioxide outside. |
33014804 | The extent of COVID-19 pneumonia was correlated with inpatient management (p = 0.003) and oxygen therapy requirements (p < 0.001). |
33015423 | ATMO-Vent is capable of adjusting the Fraction of Inspiratory Oxygen (FiO2) levels, Tidal Volume (TV), frequency of breaths, Inspiratory/Expiratory ratio (I/E), Peak Inspiratory Pressure (PIP) and Positive End-Expiratory Pressure (PEEP). |
33015428 | Following the inflammatory response, BSs induce the production of cationic proteins, reactive oxygen species (ROS) and lysozyme, and thus can be utilized for therapeutic purposes. |
33015643 | Eligibility criteria were age 18 years or older; severe pneumonia with pulmonary infiltrates consistent with pneumonia, a clinical history of severe shortness of breath within the past 14 days, or a need for non-invasive or invasive ventilation; severe disease defined as a ratio of partial pressure of arterial oxygen to fractional concentration of oxygen in inspired air (PaO2/FiO2) between 100 mm Hg and 250 mm Hg in the supine position; and severe acute respiratory syndrome coronavirus 2 infection confirmed by RT-PCR. |
33015645 | In the multistate model, using daily cHIS score as a time-dependent variable, the cHIS hazard ratio for worsening from low to moderate oxygen requirement was 1·4 (95% CI 1·2-1·6), from moderate oxygen to high-flow oxygen 2·2 (1·1-4·4), and to mechanical ventilation 4·0 (1·9-8·2). |
33019838 | Antiviral photodynamic therapy (aPDT) is based on the reaction between a photo-sensitive agent and a light source in the presence of oxygen which can produce oxidative and free radical agents to damage the virus’ structures. |
33020140 | It included personal history, antigen swabs, blood tests, spirometry, resting/stress-test ECG with oxygen saturation monitoring, echocardiogram, Holter and chest CT. […] In this small cohort of athletes with previous asymptomatic/mild SARS-CoV-2 infection, a comprehensive screening protocol including blood tests, spirometry, resting ECG, stress-test ECG with oxygen saturation monitoring and echocardiogram did not identify relevant anomalies. |
33020762 | Lung ultrasound may better correlate with the oxygen requirement and overall condition of the patient than chest radiographs - a pertinent consideration given the imminent advance of the pandemic into resource-poor zones where timely access to roentgenological imaging may be sparse. |
33020836 | This observational study enrolled patients with moderate to severe SARS-CoV-2 pneumonia [arterial oxygen partial pressure (PaO2)/fraction of inspired oxygen (FiO2) <200 mmHg] who received lopinavir/ritonavir and HCQ plus either corticosteroids (CS group, n = 50) or corticosteroids and baricitinib (BCT-CS group, n = 62). […] The primary end point was the change in oxygen saturation as measured by pulse oximetry (SpO2)/FiO2 from hospitalization to discharge. […] Secondary end points included the proportion of patients requiring supplemental oxygen at discharge and 1 month later. […] A higher proportion of patients required supplemental oxygen both at discharge (62.0% vs 25.8%; reduction of the risk by 82%, OR adjusted for IPSW, 0.18; 95% CI: 0.08, 0.43; P < 0.001) and 1 month later (28.0% vs 12.9%, reduction of the risk by 69%, OR adjusted for IPSW, 0.31; 95% CI: 0.11, 0.86; P = 0.024) in the CS vs BCT-CS group. . |

33043285 | The utility of heated and humidified high-flow nasal oxygen (HFNO) for severe COVID-19-related hypoxaemic respiratory failure (HRF), particularly in settings with limited access to intensive care unit (ICU) resources, remains unclear, and predictors of outcome have been poorly studied. […] The median (IQR) arterial oxygen partial pressure to fraction inspired oxygen ratio (PaO2/FiO2) was 68 (54-92) in 293 enroled patients. […] A higher ratio of oxygen saturation/FiO2 to respiratory rate within 6 h (ROX-6 score) after HFNO commencement was associated with HFNO success (ROX-6; AHR 0.43, 0.31-0.60), as was use of steroids (AHR 0.35, 95%CI 0.19-0.64). |
33045281 | We evaluated the accuracy of clinical signs and these biomarkers in predicting 30-day intubation/mortality, and oxygen requirement by calculating the area under the receiver operating characteristic curve (AUROC) and by classification and regression tree analysis. […] Of 76 COVID-19 patients included, 24 were outpatients or hospitalized without oxygen requirement, 35 hospitalized with oxygen requirement and 17 intubated/died. […] We found that soluble triggering receptor expressed on myeloid cells (sTREM-1) had the best prognostic accuracy for 30-day intubation/mortality (AUROC 0.86; 95% CI 0.77-0.95) and interleukin-6 (IL-6) measured at presentation to the ED had the best accuracy for 30-day oxygen requirement (AUROC 0.84; 95% CI 0.74-0.94) . […] An IL-6-based algorithm had 98% sensitivity and 0.04 negative likelihood ratio (NLR) for 30-day oxygen requirement. sTREM-1 and IL-6 concentrations in COVID-19 in the ED have good predictive accuracy for intubation/mortality and oxygen requirement. sTREM-1- and IL-6-based algorithms are highly sensitive to identify patients with adverse outcome and could serve as early triage tools. |
