Name

rdim0pa

Label

Overall Respiratory Disturbance Index (RDI) at 0% desaturation with arousal

Description

[(total number of apneas and hypopneas with arousal) / (hours of sleep)]

Calculation
rdim0pa = 60*(hremba +hroa + hnrba + hnroa +carba + caroa + canba + canoa + oarba + oaroa + oanba + oanoa + marbpa + maropa + manrbpa + manropa) / slpprdp
