Name
rdim4ps
Label
Overall supine RDI at 4% desaturation
Description

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

Calculation
rdim4ps = 60*(hrembp4 + hnrbp4 + carbp4 + canbp4 + oarbp4 + oanbp4 + marbp4 + manrbp4)/(remepbp+nremepbp)
Units
events per hour
