Label
Apnea-Hypopnea Index: (Apneas with >= 3% oxygen desaturation and with or without arousal + hypopneas with > 30% flow reduction and >= 3% oxygen desaturation and with or without arousal) / hour of sleep from type I polysomnography
Description

[(total number of apneas and hypopneas associated with >= 3% oxygen desaturation) / (hours of sleep)]

Calculation
rdi3p = 60 * ( hrembp3 + hrop3 + hnrbp3 + hnrop3 + carbp3 + carop3 + canbp3 + canop3 + oarbp3 + oarop3 + oanbp3 + oanop3 ) / slpprdp
