Experts estimate that one out of every three people suffer from some form of a sleep disorder. Many of these people suffer needlessly simply because they are unaware that a problem exists.

Polysomnogram is a test that measures activity during sleep. Each test will vary depending on the individual case, and some of the measurements taken may include:

Brain waves, EEG (skin, surface, electrodes placed on the head)

Heart beats, EKG (skin, surface electrodes placed on the chest)

Eye movements, EOG (skin, surface electrodes placed on the face above and below the eyes)

Muscle tension, Chin EMG (skin, surface electrodes placed on the chin)

Leg movement, Leg EMG (skin, surface electrodes placed on the lower leg)

Breathing effort and movements (stretch gauges placed around the chest and/or the stomach)

Blood oxygen levels, SaO2 (measured with a device called oximeter which uses a small sensor attached to the end of a finger)

No blood will be drawn



Why record all these things?
See a bigger imageDuring sleep the body functions differently than while awake. Disrupted sleep can disturb daytime activities, and occasionally cause medical problems that can be a significant risk to you overall health.

 

How can I sleep with all these things on me?
Surprisingly, most people sleep very well. The body sensors are applied so that you can turn or move during sleep. Generally, you will not be aware that you are wearing the devices after they have been on for a short time. Our staff tries to make the facility as comfortable and similar as possible to your home surroundings. And many patients report that they can actually sleep better here than at home. Remember that this is not a test, but merely a recording of how you sleep.

Will the sensor devices hurt?
No. Sometimes in rubbing the skin and putting on the electrodes, there are mild and temporary skin irritations.

Will I be given any drugs to help me sleep?
No. We prefer, to the extent medically possible, that you be off sleeping medications for at least eight days before coming for the test. It is also important not to consume any alcohol or caffeinated beverages on the day of the testing.

Do not stop any medications without first consulting your primary care doctor. The only medication, which should be discontinued are those that keep you alert or medications that help you sleep.

What happens to the polysomnogram?
See a bigger imageThe records of your sleep test will probably be about 1,100 pages long, and it will be scored and then interpreted by a physician on our sleep disorder staff. The information will then be used to give a diagnosis and recommended treatment. This final report will then be forwarded to your referring physician. The entire process can take up to five working days.
