Label
Obstructive Apnea-Hypopnea Index: (Obstructive apneas with no oxygen desaturation threshold used and with or without arousal+ hypopneas with > 30% flow reduction and >= 3% oxygen desaturation or with arousal) / hour of sleep from type II polysomnography
Description

Calculated - Summary metric of sleep disordered breathing events. The definition for hypopneas is consistent with the following clinical guidelines: (1) American Academy of Sleep Medicine (AASM) 2007 Manual (2012 update) (recommended). Berry RB et al. 2012 (PubMed ID:23066376), and (2) American Academy of Sleep Medicine (AASM) 2015 (recommended) [Berry RB et al. The AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specifications, Version 2.2. American Academy of Sleep Medicine, Darien, IL, 2015.]
