rdim0ps

Label

Overall supine Respiratory Disturbance Index (RDI) at 0% desaturation

Description

Supine Respiratory Disturbance Index (RDI) at all desaturations [(total number of apneas and hypopneas in supine body position) / (hours of sleep)]

Calculation
rdim0ps = 60*(hrembp + hnrbp + carbp + canbp + oarbp + oanbp + marbp + manrbp)/(remepbp+nremepbp)
Units
events per hour
