Abstract
Hypoxemia whether critical or not is a complication associated with airway management. The abruptness with which the hypoxic events can occur during airway management in anticipated as well as unanticipated difficult airways provide very little time to the airway managers to avoid the whirlpool of complications that can ensue if hypoxia persists. An understanding of the etiology and mechanisms of hypoxemia and the techniques that can ensure oxygenation for a prolonged time provide a safe window to think and execute the airway management plans. Paraoxygenation is one such technique that ensures an uninterrupted oxygen supply to the patient after the onset of apnoea and prolongs the safe apnoea time significantly.
