rdirem3p
Label
Apnea-Hypopnea Index (REM): (Apneas with no oxygen desaturation threshold used and with or without arousal and hypopneas with > 30% flow reduction and with >= 3% oxygen desaturation and with or without arousal)/ hours of REM sleep from type I polysomnography
Description

Calculation
rdirem3p = 60 * ( hrembp3 + hrop3 + carbp3 + carop3 + oarbp3 + oarop3 ) / minremp
Units
events per hour
