Name

rdimrem3p

Label

Overall rapid eye movement sleep (REM) Respiratory Disturbance Index (RDI) at >=3% desaturation

Description

[(total number of apneas and hypopneas in rapid eye movement sleep (REM) associated with >= 3% desaturation) / (hours of rapid eye movement sleep (REM))]

Calculation
rdimrem3p = 60*(hrembp3 + hrop3 + carbp3 + carop3 + oarbp3 + oarop3 + marbp3 + marop3) / minremp
Units
