Abstract
Apneic oxygenation during intubation is the application of oxygen via a nasal cannula, which is left in place throughout laryngoscopy. The flow rate of oxygen is set to at least 15 L/min and theoretically reduces the risk of oxygen desaturation and hypoxemia during the procedure. Over the last 5 years, there have been several studies published on this topic with differing results. Despite conflicting results, use of apneic oxygenation is becoming more prevalent and is being implemented into standard operating procedures in some clinical settings. Because of the low risk of adding a nasal cannula during intubation and the potential benefit of reducing the incidence of hypoxemia and severe oxygen desaturation, it would be prudent to implement apneic oxygenation when available.
