Understanding preoxygenation and apneic oxygenation during intubation in the critically ill

The most common adverse event encountered during the intubation of critically ill patients is oxygen desaturation, which is often a harbinger of serious complications such as cardiovascular collapse, anoxic brain injury, and death. It is imperative to attenuate this risk by optimizing preoxygenation prior to intubation. This paper explores the physiology and challenges related to preoxygenation and maintenance of oxygenation during intubation in these high-risk patients.
