Childhood Adenotonsillectomy Trial (CHAT) Apnea-Hypopnea Index (AHI) - Obstructive and Mixed Apnea-Hypopnea Index: (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 from type I polysomnography
Calculated - Summary metric of sleep disordered breathing events. The definition of hypopnea events is consistent with the American Academy of Sleep Medicine (AASM) 2007 Manual (pediatric). [Iber C et al. The AASM manual for the scoring of sleep and associated events: rules, terminology and technical specifications. Vol. 1. Westchester, IL: American Academy of Sleep Medicine, 2007] |
