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.
Learn what the AHI is and how the measure is used to assess the severity of sleep apnea and your response to therapy. AHI, or the apnea-hypopnea index, is a numerical measure that accounts for the number of pauses in your breathing per hour of sleep. These breathing disturbances are typically associated with either a brief arousal or awakening from sleep or a 3 to 4 percent drop in the blood oxygen levels, called a desaturation.
