Importance High-flow nasal oxygen is recommended as initial treatment for acute hypoxemic
respiratory failure and is widely applied in patients with COVID-19. Objective To assess …

Importance Helmet noninvasive ventilation has been used in patients with COVID-19 with
the premise that helmet interface is more effective than mask interface in delivering …

Importance Continuous positive airway pressure (CPAP) and high-flow nasal oxygen
(HFNO) have been recommended for acute hypoxemic respiratory failure in patients with …

Importance The benefit of high-flow nasal cannula oxygen (high-flow oxygen) in terms of
intubation and mortality in patients with respiratory failure due to COVID-19 is controversial …

BACKGROUND: The efficacy of noninvasive oxygenation strategies (NIOS) in treating
COVID-19 disease is unknown. We conducted a prospective observational study to assess …

High-flow nasal oxygen (HFNO) and non-invasive ventilation (NIV) have been used to
manage early acute hypoxemic respiratory failure (AHRF) caused by COVID-19. As there is …

Background Both continuous positive airway pressure (CPAP) and high-flow nasal
oxygenation (HFNO) have been recommended for acute respiratory failure in COVID-19 …

Rationale In patients with COVID-19 pneumonia and mild hypoxaemia, the clinical benefit of
high-flow nasal oxygen (HFNO) remains unclear. We aimed to examine whether HFNO …

Purpose We aimed to describe the use of high-flow nasal oxygen (HFNO) in patients with
COVID-19 acute respiratory failure and factors associated with a shift to invasive mechanical …

BACKGROUND: High-flow nasal cannula (HFNC) oxygen and noninvasive ventilation (NIV)
have been widely used in patients with acute hypoxic respiratory failure (AHRF) due to …
