Name
rdi4p
Label
Overall Respiratory Disturbance Index (RDI) at >=4% oxygen desaturation
Description

Ratio of the count of all apneas (central and obstructive) and hypopneas associated with at least a >=4% oxygen desaturation to the total sleep time expressed in hours

Calculation
rdi4p = 60 * ( hrembp4 + hrop4 + hnrbp4 + hnrop4 + carbp4 + carop4 + canbp4 + canop4 + oarbp4 + oarop4 + oanbp4 + oanop4 ) / slpprdp
