Name

rdimnr4p

Label

Overall non-rapid eye movement sleep (NREM) Respiratory Disturbance Index (RDI) at >=4% desaturation

Description

[(total number of apneas and hypopneas in non-rapid eye movement sleep associated with >= 4% desaturation) / (hours of non-rapid eye movement sleep (NREM))]

Calculation
rdimnr4p = 60*(hnrbp4 + hnrop4 + canbp4 + canop4 + oanbp4 + oanop4 + manrbp4 + manrop4) / (slpprdp - minremp)
Units
events per hour
Type
numeric
