What is Polysomnography?

You went to see your doctor, and after some discussion about your sleep problems he may have referred you for a sleep study. A sleep study measures what is happening while you sleep. For a slightly more detailed picture of your sleep performance, you spend the night in a sleep lab.

Polysomnography records your brain waves, the oxygen level in your blood, heart rate and breathing, as well as eye and leg movements during the study.

Some sleep disorders like central apnea are better diagnosed in a sleep lab. As well, some insurance companies will not pay for an in-home test but will cover a test executed in a sleep lab.

Preparing for a Sleep Study

To prepare for your sleep study, pack

If your doctor believes polysomnography is a necessary step in your health, a good way to prepare is to pack an overnight bag with essentials such as a toothbrush, toothpaste, comfortable clothes to sleep in, and a change of clothes for the morning. Pack a book because you go to sleep until the time of night you normally would.

Bring any prescribed medications to take at your normal time.  Bring some personal belongings like a pillow and a blanket that will make you more comfortable.  It also helps to go through the daily routine as normally as possible, avoiding naps and caffeine.

During the Sleep Study

The sleep techs will attach sensors to your body to monitor you while you sleep. The sensors are painless, but it may help you to let the Sleep Technician know if you are allergic to adhesives. The sensors will measure brain waves, chin muscle activity, heart rate, breathing, oxygen levels and leg movements.

It is quite common that you may not sleep as well at the sleep center as you would at home, but this rarely affects the results of the test. After you wake up, there may be a morning questionnaire to assess your sleep experience. The board-certified Sleep Physician will read the results and make any necessary recommendations such as a CPAP or BiPAP machine.
