Importance The effect of high-flow oxygen therapy vs conventional oxygen therapy has not
been established in the setting of severe COVID-19. Objective To determine the effect of …

Oxygen is a life‐saving therapy but, when given inappropriately, may also be hazardous.
Therefore, in the acute medical setting, oxygen should only be given as treatment for …

Background Nasal high flow delivered at flow rates higher than 60 L/min in patients with
acute hypoxemic respiratory failure might be associated with improved physiological effects …

The management of acute respiratory failure may require, among other measures, airway
control, mechanical ventilation, and hemodynamic stabilization. About 60% of critically ill …

Objective. To compare the safety and efficacy of transnasal high‐flow oxygen therapy
(HFNT) and noninvasive positive pressure ventilation (NIV) in the treatment of chronic …

Background High-flow nasal cannula (HFNC) has been proven effective in improving
patients with acute hypoxemic respiratory failure (AHRF), but a discussion of its use for initial …

Mallampati score has been identified and accepted worldwide as an independent predictor
of difficult intubation and obstructive sleep apnea. We aimed to determine whether …

BACKGROUND: Endotracheal intubation is a common procedure associated with adverse
events, including severe desaturation. Many patients receive noninvasive respiratory …

Background Non-invasive ventilation (NIV), although effective in treating hypercapnic
respiratory failure, has not demonstrated the same efficacy in treating acute hypoxaemic …

Background Acute respiratory failure (ARF) is a respiratory disease in which ventilation
