rdi4pa rdi4ps
Name
rdi4pns
Label
Overall RDI (non-Supine) at 4% oxygen desaturation
Description

Non-Supine RDI at 4% oxygen desaturation [(Total number of apneas and hypopneas in non-supine body position associated with >= 4% oxygen desaturation) / (hours of sleep)]

Calculation
rdi4pns = 60 * ( hrop4 + hnrop4 + carop4 + canop4 + oarop4 + oanop4 ) / ( remepop + nremepop )
Units
events per hour
Type
numeric
