Name

rdimnr3p

Label

Overall non-rapid eye movement sleep (NREM) Respiratory Disturbance Index (RDI) at >=3% desaturation

Description

[(total number of apneas and hypopneas in non-rapid eye movement sleep (NREM) associated with >= 3% desaturation) / (hours of non-rapid eye movement sleep (NREM))]

Calculation
rdimnr3p = 60*(hnrbp3 + hnrop3 + canbp3 + canop3 + oanbp3 + oanop3 + manrbp3 + manrop3) / (slpprdp - minremp)
Units
events per hour
Type
numeric
