rdim4p capdur
Name
rdim4pa
Label
Overall RDI at 4% desaturation or arousal
Description

RDI with arousals at 4% desaturation [(total number of apneas and hypopneas with arousal associated with >= 4% desaturation) / (hours of sleep)]

Calculation
rdim4pa = 60*(hremba4 +hroa4 + hnrba4 + hnroa4 +carba4+ caroa4 + canba4 + canoa4 + oarba4 + oaroa4 + oanba4 + oanoa4 + marbpa4 + maropa4 + manrbpa4 + manropa4) / slpprdp
