About

This study will compare the impact of a classical aerosol mask above low-flow nasal cannula on the arterial oxygen tension in patients with COVID-19.

Full description

Hospitalized patients with COVID-19 typically present with hypoxemia. In some patients, hypoxemia can be corrected with low flow nasal cannula. When placed above nasal cannula, some systems have demonstrated their interest in improving the performance of the patient's oxygen delivery. For example, two recent studies have shown that adding a Double-Trunk Mask (DTM) or Surgical Mask (SM) above nasal cannula has the potential to improve the PaO2 despite no change in oxygen output (1, 2) . However, no study has compared the effect on PaO2, of the addition of a classical aerosol mask above nasal canula.
