rdinr0p rdinr4p
Name
rdinr2p
Label
Overall RDI (NREM) at 2% oxygen desaturation
Description

Non-REM RDI at 2% oxygen desaturation [(Total number of apneas and hypopneas in non-REM sleep associated with >= 2% oxygen desaturation) / (hours of NREM sleep)]

Calculation
rdinr2p = 60 * ( hnrbp2 + hnrop2 + canbp2 + canop2 + oanbp2 + oanop2 ) / ( slpprdp - minremp )
Units
events per hour
Type
numeric
