Name
rdimnr0p
Label
Apnea-Hypopnea Index (NREM): (Apneas with no oxygen desaturation threshold used and with or without arousal+ hypopneas with > 50% flow reduction and with no oxygen desaturation used and with or without arousal) / hours of NREM sleep from type I polysomnography
Description

Non-rapid eye movement sleep (NREM) Respiratory Disturbance Index (RDI) at all desaturations [(total number of apneas and hypopneas in non-rapid eye movement sleep (NREM)) / (hours of non-rapid eye movement sleep (NREM))]

Calculation
rdimnr0p = 60*(hnrbp + hnrop + canbp + canop + oanbp + oanop + manrbp + manrop) / (slpprdp - minremp)
