Apnea-Hypopnea Index: (All apneas with no oxygen desaturation threshold used + hypopneas with > 30% flow reduction and with >= 4% oxygen desaturation) / hour of estimated sleep from type III home sleep apnea test
Description
Calculated - Summary metric of sleep disordered breathing events. The definition of hypopnea events is consistent with the following clinical guidelines: (1) AASM 2012 update (alternative) Berry RB et al. 2012 (PubMed ID:23066376), and (2) AASM 2015 (acceptable) [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.].
