Comparison of Several Oxygenation Targets With Different Oxygen Interfaces - Impact on Oxygen Flow Rates
Opening soon NCT06646991
Run by Laval University · for 18 and older · All sexes
What this study is about
Oxygen therapy is at the heart of the healthcare system. Oxygen flow rates depend on a number of confounding factors confounding factors (target used, skin pigmentation, pulse oximeter used, etc.) The investigators have recently have recently demonstrated that the combination of these factors (different peripheral oxygen saturation (SpO2) targets and different oximeters) can have a significant impact on oxygen flows rates. The effect on oxygen flow was not simply additive . The aim of this study is to evaluate the impact of the interface used on oxygen flow rates in different patient populations (main objective). The investigatoers also evaluate the impact of the interface on carbon dioxide (PaCO2), in particular with closed oxygen masks, with which rebreathing is theoretically possible (secondary objective). secondary objective).
