omai4p qsahi
Name
omai4pa
Label
Obstructive/mixed apnea index >=4% or arousal
Description

[(total number of obstructive apneas with >= 4% desaturation or arousal + total number of mixed apneas with >= 4% desaturation or arousal) / (hours of sleep)]

Calculation
omai4pa = 60*(oarba4 + oaroa4 + oanba4 + oanoa4 + marbpa + maropa + manrbpa + manropa) / slpprdp
Units
events per hour
