Name
rdi5p
Label
Overall RDI at 5% oxygen desaturation
Description

RDI at 5% oxygen desaturation [(Total number of apneas and hypopneas associated with >= 5% oxygen desaturation) / (hours of sleep)]

Calculation
rdi5p = 60 * ( hrembp5 + hrop5 + hnrbp5 + hnrop5 + carbp5 + carop5 + canbp5 + canop5 + oarbp5 + oarop5 + oanbp5 + oanop5 ) / slpprdp
