Endotracheal Suctionning During Positive Pressure Extubation in ICU

The aim of this clinical trial 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. 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.
