There is one clinical trial.
This study will investigate the impact of the Double-Trunk Mask (DTM) on the reduction of oxygen titration in patients with severe hypoxemia.
Description: The O2 output will be adjusted to maintain a SpO2 of 94% using both systems for administering O2. The O2 flow will be read from the position of the ball in flow meters.
Measure: Change in O2 output Time: At baseline and 30 minutes after wearing both systemsDescription: A Likert scale from 0 to 5 will be used to measure the subjective comfort of the patient while wearing the standard interface for administering O2 and/or the DTM
Measure: Comfort with the interfaces Time: 30 minutes after wearing both systemsDescription: Oxygen tension (PaO2) in mmHg will be analyzed from a sample taken from the arterial system
Measure: Changes in PaO2 Time: At baseline and 30 minutes after wearing DTMDescription: Carbon dioxide tension (PaCO2) in mmHg will be analyzed from a sample taken from the arterial system.
Measure: Changes in PaCO2 Time: At baseline and 30 minutes after wearing DTMDescription: Potential of Hydrogen (pH) will be analyzed from a sample taken from the arterial system.
Measure: Changes in pH Time: At baseline and 30 minutes after wearing DTMDescription: Respiratory rate is measured during one minute by visual inspection.
Measure: Changes in respiratory rate Time: At baseline and 30 minutes after wearing both systems
