Name

rdimrem4p

Label

Overall rapid eye movement sleep (REM) Respiratory Disturbance Index (RDI) at >=4% desaturation

Description

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

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