Official Title
Impact of the Double-Trunk Mask on Oxygenation Titration in Patients With COVID-19
Brief Summary

This study will investigate the impact of the Double-Trunk Mask (DTM) on the reduction of oxygen titration in patients with severe hypoxemia.

Detailed Description

The Double-Trunk Mask (DTM) is a device designed to increase the fraction of inspired oxygen in patients who receive oxygen therapy. The mask is composed of a regular aerosol mask with corrugated tubing (15 cm length) inserted into two lateral holes.

Each included patient will wear standard nasal cannula in addition to the Double-Trunk Mask for 30 minutes, then only their standard oxygen interface for the next 30 minutes. While maintaining the oxygen saturation by pulse oximetry (SpO2) at a target value of 94%, the impact of the DTM will be assessed by measuring the change of oxygen flow given to the patient.

Other: Standard interface
The standard interface for administering oxygen (nasal cannula or oxygen mask) is worn by the patient. Oxygen output is adapted to reach a SpO2 target of 94%.

Device: Double-Trunk Mask
The standard nasal cannula interface accompanied with the DTM is worn by the patient. Oxygen output is adapted to reach a SpO2 target of 94%.
O2 DTM+
