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.
1 An AHI of 30 or more indicates severe sleep apnea. 2  If your machine does not record your AHI, you will have to make adjustments slowly based on what feels better. 3  Making adjustments based on how you feel is, by definition, very subjective.
