Measures of Sleep Apnea

The results of a sleep study will show both the type of sleep apnea, and provide a number of measures of its severity.

The Apnea Index (AHI) is the number of apneas and hypopneas per hour.
• Normal is AHI 0-10 events per hour
• Mild 10-15 events per hour
• Moderate 15-30 events per hour
•evere 30+ events per hour

The degree and frequency of oxygen desaturations may also be an important parameter to measure to assess risk, particularly in patients who are compromised with other underlying cardiovascular conditions.
