rdi2pa rdi2ps
Name
rdi2pns
Label
Overall RDI (non-Supine) at 2% oxygen desaturation
Description

Non-Supine RDI at 3% oxygen desaturation [(Total number of apneas and hypopneas in non-supine body position associated with >= 3% oxygen desaturation) / (hours of sleep)]

Calculation
rdi2pns = 60 * ( hrop2 + hnrop2 + carop2 + canop2 + oarop2 + oanop2 ) / ( remepop + nremepop )
Units
events per hour
Type
numeric
