How AHI Is Used. The AHI is used to classify the severity of your sleep apnea, according to the following criteria for adults: Normal: fewer than 5 events per hour of sleep. Mild: 5-14.9 events per hour of sleep. Moderate: 15-29.9 events per hour of sleep. Severe: greater than 30 events per hour of sleep.
An AHI of 1-5 is very mildly increased, 5-10 is mildly increased, 10-20 is moderately increased, and greater than 20 is severely abnormal. Obstructive hypopnea (OH) in children is a sleep-related breathing disorder that is considered a variation of obstructive sleep apnea. Children with OH may have an AHI in the normal range, but they have episodic periods of hypercapnia, as identified on the basis of end-tidal (ET) CO2 monitors.
