Name
rdi2p
Label
Overall RDI at 2% oxygen desaturation
Description

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

Calculation
rdi2p = 60 * ( hrembp2 + hrop2 + hnrbp2 + hnrop2 + carbp2 + carop2 + canbp2 + canop2 + oarbp2 + oarop2 + oanbp2 + oanop2 ) / slpprdp
Units
events per hour
