Apnea-Hypopnea Index : (All apneas + hypopneas with >=30% nasal cannula [or alternative sensor] reduction and >= 3% oxygen desaturation or with arousal) / hour of sleep
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. American Academy of Sleep Medicine, Darien, IL, 2015.]
