General anaesthesia induction leads to an apneic period which may be longer in case of a difficult airway. Apnea interrupts oxygen supply and may lead to hypoxemia. Desaturation is associated with several serious complications, like brain injuries, rhythm disturbances or cardiac arrest. Preoxygenation and apneic oxygenation help to prevent desaturation.

Keywords: Apneic ventilation, Continuous positive airway pressure, Hypoxia, Hyperoxia, Oxygenation, Oxygen therapy, Preoxygenation, Rapid sequence intubation, Tidal volume breathing, Ventilation.
