Endotracheal Suctionning During Positive Pressure Extubation in ICU

This is a prospective, randomised, controlled trial. The aim of this study is to evaluate endotracheal suctioning during positive pressure extubation in mechanically ventilated adult patients (over 18 years old) in the intensive care unit (ICU). The main question it aims to answer is whether the intervention improves the respiratory oxygenation index (ROX) three hours after extubation compared to no endotracheal suction during positive pressure extubation. Inclusion : Participants who meet eligibility criteria will be randomized into experimental arm (endotracheal suctioning during positive pressure extubation) or control arm (no endotracheal suction during positive pressure extubation). Intervention and Follow-up : participants will only need to be extubated by the nursing team in the ICU. Follow-up will consist of evaluating respiratory rate, pulse oximetry and inspired oxygen fraction for three hours following extubation. End of study : at the end of the study visit (28 days after extubation), vital status of participants will be recorded.
