Apnea-Hypopnea Index (NREM): Apneas with >= 4% oxygen desaturation and with or without arousal+ hypopneas with > 30% flow reduction and with >= 4% oxygen desaturation and with or without arousal / hour of NREM sleep from type II polysomnography
Apnea-Hypopnea Index (NREM): Apneas with >= 4% oxygen desaturation and with or without arousal+ hypopneas with > 30% flow reduction and with >= 4% oxygen desaturation and with or without arousal / hour of NREM sleep from type II polysomnography

Calculated - Summary metric of sleep disordered breathing events
