What Are the Risk Factors for Obstructive Sleep Apnea?

In addition to being overweight and getting older, other risk factors for obstructive sleep apnea include:

*smoking
*high blood pressure
*having risk factors for heart failure or stroke


How Is Obstructive Sleep Apnea Diagnosed?

To diagnose obstructive sleep apnea, your doctor will perform a physical exam and take a medical and sleep history. The doctor may also ask people who live with you about your sleeping habits.

You might also be asked to take a sleep test called a polysomnogram, or PSG. Sleep testing is performed in a sleep lab and is supervised by a trained technologist. The test will measure various body functions, including:

*air flow
*blood oxygen levels
*breathing patterns
*electrical activity of the brain
*eye movements
*heart rate
*muscle activity

After the study is completed, the technologist will tally the number of times your breathing was impaired during sleep and grade the severity of sleep apnea. In some cases, a multiple sleep latency test is performed on the day after the overnight test. This measures how quickly you fall asleep. In this test, patients are given several opportunities to fall asleep during the course of a day when they normally would be awake.
