Part Description

LP145624-5   Apnea hypopnea index
The apnea-hypopnea index (AHI) is an index of sleep apnea severity that combines apneas and hypopneas. The apneas (pauses in breathing) must last for at least 10 seconds and are associated with a decrease in blood oxygenation. Combining these gives an overall sleep apnea severity score that evaluates both number sleep disruptions and degree of oxygen desaturation (low blood level).

The AHI, as with the separate apnea index and hypopnea index, is calculated by dividing the number of events by the number of hours of sleep. (AHI values are typically categorized as 5-15/hr = Mild; 15-30/hr = Moderate; and > 30/h = Severe.) Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
