Tracheal and airway disorders

Tracheal intubation in critically ill patients remains high-risk despite advances in equipment, technique, and clinical guidelines.1 Approximately one in three patients experience moderate complications, and almost one in four experience severe complications.2,3 Peri-intubation cardiac arrest occurs in 2–4% of cases, and is highly associated with peri-intubation oxygen desaturation and hypotension.2,4 A 2018 study reported that patients who desaturated or became hypotensive had 3.99 and 3.41 times higher adjusted odds, respectively, of a cardiac arrest compared with those who did not.
