Name

rdim0p

Label

Overall Respiratory Disturbance Index (RDI) at 0% desaturation

Description

[(total number of apneas and hypopneas) / (hours of sleep)]

Calculation
rdim0p = 60*(hrembp + hrop + hnrbp + hnrop + carbp + carop + canbp + canop + oarbp + oarop + oanbp + oanop + marbp + marop + manrbp + manrop) / slpprdp
