Review of Hypoxemia Quantification Methods for Assessing the Severity of Obstructive Sleep Apnea
Obstructive sleep apnea (OSA) is a common nocturnal breathing disorder characterized by recurrent upper airway obstruction during sleep, leading to sleep fragmentation and intermittent hypoxemia. The apnea-hypopnea index (AHI) is the most widely used clinical metric to assess OSA severity; however, the AHI fails to cap...
