Name

oahi3

Label

Obstructive apnea hypopnea (>=3% desaturation) index

Description

{[(total number of obstructive apneas) + (total number of hypopneas associated with >= 3% desaturation)] / (hours of sleep)}

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