oahi_oa0uhp3x3u_f1t1
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.

Calculation
