简要总结
This study will compare the impact of the Double-Trunk Mask (DTM) with the Non-Rebreather Mask (NRM) on the blood gases of patients with severe hypoxemia.
详细描述
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 the standard Non-Rebreather Mask (NRM) which is the standard delivery oxygen system for patients with acute severe hypoxemia. Then the patients will wear the DTM for 30 minutes. Finally the DTM will be replaced by the NRM for the next 30 minutes. The impact of both oxygen delivery system will be assessed by measuring the change of blood gases with each system.

结局指标
主要结局
Changes in PaO2
时间窗: At baseline and 30 minutes after wearing DTM
Oxygen tension (PaO2) in mmHg will be analyzed from a sample taken from the arterial system
次要结局
- Dyspnea with the oxygen delivery systems(30 minutes after wearing both systems)
- Changes in PaCO2(At baseline and 30 minutes after wearing DTM)
- Changes in respiratory rate(At baseline and 30 minutes after wearing both systems)
- Changes in pH(At baseline and 30 minutes after wearing DTM)
- Comfort with the oxygen delivery systems(30 minutes after wearing both systems)
