Apnea-Hypopnea Index: (All apneas with no oxygen desaturation threshold used and with or without arousal + hypopneas with > 50% flow reduction and without oxygen desaturation threshold used and with or without arousal + hypopneas with > 30% flow reduction and with >= 3% oxygen desaturation or with arousal) / hour of sleep from type I polysomnography

rditstpsg under Sleep Monitoring/Polysomnography/Apnea-Hypopnea Indices in APPLES variables

Hypopneas are defined using two criteria: a > 50%, but <= 90% amplitude decrease from baseline of the nasal pressure signal; or if there was a clear amplitude reduction of the nasal pressure signal that did not reach the above criterion but it was associated with either an oxygen desaturation > 3% or an arousal, and the event duration was >= 10 seconds. The definition of hypopnea events is consistent with the following clinical guidelines: American Academy of Sleep Medicine (AASM) Chicago 1999 standard.

Apnea-Hypopnea Index : (All apneas + hypopneas with >=30% nasal cannula [or alternative sensor] reduction and >= 3% oxygen desaturation or with arousal) / hour of sleep

Harmonized by the NSRR team. 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.
