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.
AHI (Apnea Hypopnea Index) is the number of apneas and hypopneas per hour. Or an index for sleep apnea. 5-20 mild, 21-50 moderate, above 50 severe. The Greek word âapneaâ means âwithout breath.â You stop breathing during sleep for ten seconds or longer. During a Hypopnea there is airflow through your throat but at a much reduced level, which leads to not getting enough oxygen.
