rdim2p rdim2pns
Name
rdim2pa
Label
Overall RDI at 2% desaturation or arousal
Description

RDI with arousals at 2% desaturation [(total number of apneas and hypopneas with arousal associated with >= 2% desaturation) / (hours of sleep)]

Calculation
rdim2pa = 60*(hremba2 +hroa2 + hnrba2 + hnroa2 +carba2+ caroa2 + canba2 + canoa2 + oarba2 + oaroa2 + oanba2 + oanoa2 + marbpa2 + maropa2 + manrbpa2 + manropa2) / slpprdp
