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.
The ABI result can help diagnose peripheral arterial disease (PAD). A lower ABI means you might have PAD. A slight drop in the ABI with exercise, even if you have a normal ABI at rest, means that you probably have PAD. Normal. A normal resting ankle-brachial index is 1.0 to 1.4. This means that your blood pressure at your ankle is the same or greater than the pressure at your arm, and suggests that you do not have significant narrowing or blockage of blood flow. 2. Abnormal. Abnormal values for the resting ankle-brachial index are 0.9 or lower and 1.40 or higher. If the ABI is 0.91 to 1.00, it is considered borderline abnormal. 2 Abnormal values might mean you have a higher chance of having narrowed arteries in other parts of your body.
