ahi Apnea-Hypopnea Index (AHI): (All apneas with no oxygen desaturation threshold used + hypopneas with > 30% flow reduction and with >= 4% oxygen desaturation ) / hour of sleep from type I polysomnography or type III home sleep test	Apnea-Hypopnea Index (AHI): (All apneas with no oxygen desaturation threshold used + hypopneas with > 30% flow reduction and with >= 4% oxygen desaturation ) / hour of sleep from type I polysomnography or type III home sleep test Composite AHI based on the diagnostic sleep study and home sleep study. 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.
