What is Sleep Apnea?

Obstructive sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts during sleep. Several types of sleep apnea exist, but the most common type is obstructive sleep apnea, which occurs when your throat muscles intermittently relax and block your airway during sleep. The most noticeable sign of obstructive sleep apnea is snoring.

How do I know if I have Obstructive Sleep Apnea?

If you snore, have trouble sleeping, wake up often, or have excessive daytime sleepiness, you may have obstructive sleep apnea.

Is there a screening test that can be done?

Yes. A free screening test is avialable through the Sleep Lab at the ProMedica Coldwater Regional Hospital. Call 517.279.5364 to arrange for the free screening.

Why am I having a sleep study done in the Sleep Lab?

The measurement recorded during polysomnography provides a great deal of information about your sleep patterns. For example:
Brain wave and movement during sleep can help your health care team assess your sleep stages and identify disruptions in the stages that may occur due to sleep disorders such as narcolepsy and REM sleep behavior disorder
Heart and breathing rate change and changes in blood oxygen that are abnormal during sleep may suggest sleep apnea.
Frequent leg movements that disrupt your sleep may indicate periodic limb movement.
Unusual movements or behaviors during sleep may be a signs of REM sleep behavior disorder or another sleep disorder.

The information gathered during polysomnography is evaluated first by a polysomnography technologist, who uses the data to chart your sleep stages and cycles. Then that information is reviewed by your sleep center doctor.

It may take up to two weeks to receive the results of polysomnography. At a follow-up appointment, your doctor reviews the results with you and, based on the data gathered, discusses any treatment or further evaluation that you may need.

What should I expect during my sleep study?

You arrive at the sleep center in the evening for polysomnography and stay overnight. You may bring items you use for your bedtime routine, and you can sleep in your own nightclothes.
The room where polysomnography is done is similar to a hotel room, and it's dark and quiet during the test. You don't share the room with anyone else. The room has an infrared camera, so the polysomography technologists monitoring you can see what's happening in the room when the lights are out, and an audio system, so they can talk to you and hear you from their monitoring area outside the room.
After you get ready for bed, one of the technologists places sensors on your scalp, temples, chest and legs using a mild adhesive, such as glue or tape. The sensors are connected by wires to a computer, but the wires are long enough to let you move normally in bed. A small clip also is placed on you finger to monitor the level of oxygen in your blood.
While you sleep, a technologist monitors your brain waves, eye movements, heart rate, breathing pattern, blood oxygen level, body position, limb movement, snoring and other noise you may make as you sleep. All of these measurements are recorded on a continuous graph.
You are monitored throughout the night. If you need assistance, you can talk to them through the monitoring equipment. They can come into the room to detach the wires if you need to get up during the night.
Although you probably won't fall asleep as easily or sleep as well at the sleep center as you do at home, this usually doesn't affect the test results. A full night's sleep isn't required to obtain accurate polysomnography results.

What is the treatment for Obstructive Sleep Apnea?

Continuous Positive Airflow Pressure, or CPAP for short, is the most common treatment for moderate to severe obstructive sleep apnea. In many cases, you'll experience immediate symptom relief and a huge boost in your mental and physical energy. The CPAP device is a mask-like machine that provides a constant stream of air which keeps your breathing passages open while you sleep. Most CPAP devices are the size of a tissue box. There are other treatment options such as losing weight, stoppng smoking, and dental devices. A sleep center physician will work with you to find the best option.
