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.
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.

Change in PaO2 and PaCO2
Changes in PaO2 \[ Time Frame: At baseline and 30 minutes after wearing the randomized oxygen delivery system \] Oxygen tension (PaO2) in mmHg will be analyzed from a sample taken from the arterial system
Time frame: 30 minutes
Respiratory frequency
Change in respiratory rate \[ Time Frame: At baseline, 30 minutes and 60 minutes after wearing the randomized oxygen delivery system \] Respiratory frequency is measured during one minute by visual inspection
Time frame: 1 minute
