Preoxygenation for Tracheal Aspirations in Intensive Care

Throughout the entire period of their mechanical ventilation, patients will not receive additional preoxygenation before any endotracheal suctioning; their FiO2 value will be maintained constant

Throughout the entire period of their mechanical ventilation, patients will receive additional preoxygenation at 100% FiO2 for a systematic 2-minute duration prior to any endotracheal suction. Subsequently, the FiO2 will be reset to the previous default value.
