rdim5ps rdimnr2p
Name
rdimnr0p
Label
Overall non-rem RDI at 0% desaturation
Description

Non-REM RDI at all desaturations [(total number of apneas and hypopneas in non-REM sleep) / (hours of NREM sleep)]

Calculation
rdimnr0p = 60*(hnrbp + hnrop + canbp + canop + oanbp + oanop + manrbp + manrop) / (slpprdp - minremp)
Units
events per hour
Type
numeric
