Overall Rem RDI at 4% desaturation
Description

REM RDI at 4% desaturation [(total number of apneas and hypopneas in REM sleep associated with >= 4% desaturation) / (hours of REM sleep)]

Calculation
rdimrem4p = 60*(hrembp4 + hrop4 + carbp4 + carop4 + oarbp4 + oarop4 + marbp4 + marop4) / minremp
Units
events per hour
