Name
hi_hp3x0u_f1t1
Label
Hypopnea Index: (hypopneas with > 30% flow reduction and with no oxygen desaturation threshold used and with or without arousal) / hour of sleep from type I polysomnography
Description

Calculated - Summary metric of sleep disordered breathing events.

Calculation
hi_hp3x0u_f1t1 = 60 * (hrembp + hrop + hnrbp + hnrop + urbp + urop + unrbp + unrop) / ttldursp
Units
events per hour
Type
