Name

rdimrem2p

Label

Overall rapid eye movement sleep (REM) Respiratory Disturbance Index (RDI) at >=2% desaturation

Description

[(total number of apneas and hypopneas in rapid eye movement sleep (REM) associated with >= 2% desaturation) / (hours of rapid eye movement sleep (REM))]

Calculation
rdimrem2p = 60*(hrembp2 + hrop2 + carbp2 + carop2 + oarbp2 + oarop2 + marbp2 + marop2) / minremp
Units
