There was substantial crossover between the arms, but an inverse probability weighting analysis that corrected for the bias that this may have introduced did not change the results.8 Adverse events were more common in the NIV arm. Asked for Male, 34 Years. "We kept changing ventilator settings to try to find a level that worked for him, but he was just getting worse by the day. Between April 2020 and May 2021, 1,273 adults with COVID-19-related acute hypoxemic respiratory failure were randomized to receive NIV (n = 380), HFNC oxygen (n = 418), or conventional oxygen therapy (n = 475). The patients in the HFNC oxygen arm had more ventilator-free days (mean 24 days) than those in the conventional oxygen therapy arm (mean 22 days) or the NIV arm (mean 19 days; P = 0.02).

The most common symptom is dyspnea, which is often accompanied by hypoxemia. In the subgroup of severely hypoxemic patients (those with a ratio of arterial partial pressure of oxygen to fraction of inspired oxygen [PaO2/FiO2] 200 mm Hg), the intubation rate was lower in the HFNC oxygen arm than in the conventional oxygen therapy arm or the NIV arm (HR 2.07 and 2.57, respectively). In the prepandemic PROSEVA study of patients with moderate or severe early ARDS (PaO2/FiO2 <150 mm Hg) who required mechanical ventilation, the patients who were randomized to undergo prone positioning for 16 hours per day had improved survival compared to those who remained in the supine position throughout their course of mechanical ventilation.14 A meta-analysis evaluated the results of the PROSEVA study and 7 other randomized controlled trials that investigated the use of prone positioning in people with ARDS.29 A subgroup analysis revealed that mortality was reduced among patients who remained prone for 12 hours per day when compared with patients who remained in the supine position (risk ratio 0.74; 95% CI, 0.560.99).

Normally, the lungs perform the life-sustaining duty of gas exchange, providing oxygen to every cell in the body as we breathe in and ridding us of carbon dioxide each time we exhale. By having a better understanding of these underlying mechanisms, and how the combinations could vary from patient to patient, clinicians can make more informed choices about treating patients using measures like ventilation and supplemental oxygen. The researchers found that, as the disease became more severe, more immature red blood cells flooded into blood circulation, sometimes making up as much as 60 per cent of the total cells in the blood. Keep a Check on Blood Oxygen Level. Although prone positioning has been shown to improve oxygenation and outcomes in patients with moderate to severe ARDS who are receiving mechanical ventilation,14,15 there is less evidence regarding the benefit of prone positioning in awake patients who require supplemental oxygen without mechanical ventilation.
