Obstructive sleep apnea is characterized by repetitive episodes of upper airway collapse (lasting ≥10 s) during sleep. This leads to partial (hypopnea) or complete (apnea) cessation of airflow and blood gas disturbances (hypoxia and hypercapnia), despite ongoing respiratory efforts. Restoration of upper airway patency typically results in a brief awakening (arousal) from sleep. The repetitive physiological stress of obstructive sleep apnea can lead to sleep fragmentation with consequential excessive daytime sleepiness, neurocognitive and cardiovascular sequelae.
