Total Hypoxic Burden as a Supplementary Metric in Mild Obstructive Sleep Apnea

Objectives: The apnea–hypopnea index (AHI) does not capture desaturation depth or duration. We examined whether total hypoxic burden (THB) describes hypoxemic variation beyond event frequency and whether a THB threshold identifies a higher-risk subgroup in mild obstructive sleep apnea (OSA; 5≤AHI <15).Methods: We retro...
