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