Name

rdimnr2p

Label

Overall non-rapid eye movement sleep (NREM) Respiratory Disturbance Index (RDI) at >=2% desaturation

Description

[(total number of apneas and hypopneas in non-rapid eye movement sleep (NREM) associated with >= 2% desaturation) / (hours of non-rapid eye movement sleep (NREM))]

Calculation
rdimnr2p = 60*(hnrbp2 + hnrop2 + canbp2 + canop2 + oanbp2 + oanop2 + manrbp2 + manrop2) / (slpprdp - minremp)
Units
events per hour
Type
numeric
