Name
rdim3ps
Label
Overall supine RDI at 3% desaturation
Description

Supine RDI at 3% desaturation [(total number of apneas and hypopneas in supine body position associated with >= 3% desaturation) / (hours of sleep)]. will be missing if no time supine or low position sensor quality.

Calculation
rdim3ps = 60*(hrembp3 + hnrbp3 + carbp3 + canbp3 + oarbp3 + oanbp3 + marbp3 + manrbp3)/(remepbp+nremepbp)
Units
events per hour
