oahi3

Label

Obstructive apnea (all oxygen desaturations) hypopnea (>= 3% oxygen desaturation) index

Description

Ratio of the count of all obstructive apneas (all desaturations) plus the count of hypopneas associated with at least a >=3% oxygen desaturation to the total sleep time expressed in hours.

Calculation
oahi3 = 60*(hrembp3 + hrop3 + hnrbp3 + hnrop3 + oarbp + oarop + oanbp + oanop ) / slpprdp
