Impact of End-tidal Oxygen Monitoring During Preoxygenation Before Intubation for Acute Hypoxemic Respiratory Failure in ICU Setting

"According to previous studies a target of EtO2 ≥ 90% is proposed to trigger RSI and intubation. If this target is judged impossible to achieve and/or there is an imperative need to interrupt the pre-oxygenation phase, the operator is free to continue the procedure according to current recommendations.~Before the start of the inclusions, a training session on the use of the module will be organized with a reminder of the recommendations.~During the procedure, preoxygenation modalities and duration, achieved EtO2 level, conduction of the induction and intubation, minimum SpO2 and occurrence of complications will be recorded.~The procedure will stop ten minutes after completion of the orotracheal intubation procedure (defined as inflation of the balloon,clinical and capnography control)."
