Childhood Adenotonsillectomy Trial (CHAT) Apnea-Hypopnea Index (AHI) - Obstructive and Mixed Apnea-Hypopnea Index (Non-Supine): (Obstructive apneas with no oxygen desaturation threshold used and with or without arousal+ mixed apneas with no oxygen desaturation threshold used and with or without arousal+ hypopneas with > 50% flow reduction and >= 3% oxygen desaturation or arousal) / hour of sleep in non-supine position from type I polysomnography
Calculated - Summary metric of sleep disordered breathing events. Will be missing if Total Sleep Time (TST) is 0. |
