rdinr3p
Label
Apnea-Hypopnea Index (NREM): (Apneas with no oxygen desaturation threshold used and with or without arousal and hypopneas with > 30% flow reduction and with >= 3% oxygen desaturation and with or without arousal)/ hours of NREM sleep from type I polysomnography
Description

Calculated - Summary metric of sleep disordered breathing events during NREM sleep

Calculation
rdinr3p = 60 * ( hnrbp3 + hnrop3 + canbp3 + canop3 + oanbp3 + oanop3 ) / ( slpprdp - minremp )
Units
events per hour
