ahi_o0h3
Label
Obstructive Apnea-Hypopnea Index : (Obstructive apneas with no oxygen desaturation threshold used and with or without arousal+ hypopneas with > 30% flow reduction and >= 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
ahi_o0h3 = 60 * (hrembp3 + hrop3 + hnrbp3 + hnrop3 + oarbp + oarop + oanbp + oanop + urbp3 + urop3 + unrbp3 + unrop3) / slpprdp
