서로 다른 산소 인터페이스를 갖는 여러 산소화 목표 비교 - 산소 유량에 미치는 영향 (Interfaces)

2026년 11월 3일 업데이트: François Lellouche, Laval University

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).
