Label
Apnea-Hypopnea Index (Non-Supine): (Apneas with no oxygen desaturation threshold used only with arousal + hypopneas with > 50% flow reduction and with no oxygen desaturation used only with arousal) / hour of sleep in non-supine position from type I polysomnography
Description

Non-supine Respiratory Disturbance Index (RDI) at all desaturations [(total number of apneas and hypopneas in non-supine body position) / (hours of sleep)]

Calculation
rdim0pns = 60*(hrop + hnrop + carop + canop + oarop + oanop + marop + manrop)/(remepop+nremepop)
Units
events per hour
