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.
Each episode must last at least 10 sec. The AHI is one indicator of obstructive sleep apnea, although it is recognized as an imperfect diagnostic tool. An AHI of 30 or more events in an hour indicates severe sleep apnea; 15 to 29 events suggests moderate apnea; and 5 to 14 events indicates mild apnea.
