異なる酸素界面を持ついくつかの酸素化ターゲットの比較 - 酸素流量への影響 (Interfaces)
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).

Oxygen will be administered via nasal cannula up to 6 liters per minute during this period. Oxygen flow rates will be adjusted manually, with a gradual increase in flow rates to achieve a oxygen flow rates for reach the peripheral oxygen saturation (SpO2) target (92% for non chronic obstructive pulmonary disease (non COPD) patient and 90% for chronic obstructive pulmonary disease (COPD) patient). The steady state will be defined by a fixed oxygen flow rate and a stable SpO2 around the target ±2% for 15 minutes. The average oxygen flow rate during the last five minutes will be used. Oxygen will be administered via nasal cannula up to 15 liters per minute during this period. Oxygen flow rates will be adjusted manually, with a gradual increase in flow rates to achieve a oxygen flow rates for reach the SpO2 target (92% for non COPD patient and 90% for COPD patient). The steady state will be defined by a fixed oxygen flow rate and a stable SpO2 around the target ±2% for 15 minutes. The average oxygen flow rate during the last five minutes will be used. Oxygen will be administered via an open during this period. Oxygen flow rates will be adjusted manually, with a gradual increase in flow rates to achieve a oxygen flow rates for reach the SpO2 target (92% for non COPD patient and 90% for COPD patient). The steady state will be defined by a fixed oxygen flow rate and a stable SpO2 around the target ±2% for 15 minutes. The average oxygen flow rate during the last five minutes will be used. Oxygen will be administered via simple oxygen face mask during this period. Oxygen flow rates will be adjusted manually, with a gradual increase in flow rates to achieve a oxygen flow rates for reach the SpO2 target (92% for non COPD patient and 90% for COPD patient). The steady state will be defined by a fixed oxygen flow rate and a stable SpO2 around the target ±2% for 15 minutes. The average oxygen flow rate during the last five minutes will be used. |
