Preparing for a Sleep Study

Preparing for and participating in a sleep study at Glendale Adventist Medical Center is a simple process. Here are some guidelines to help make your experience as pleasant as possible.

Before You Come

On the day of your test, you can go about your normal day, with the following exceptions:

  • Don't take a nap.
  • Don't drink coffee, hot chocolate or other beverages with caffeine for at least eight hours before your test.
  • Don't drink alcohol during the entire day before your test.
  • Don't use crème rinse, hair spray, hair oil, mousse, gel or any other similar products on your hair. (These can make it difficult to apply the electrodes to your skin.)
  • Don't use bath oils, skin lotions or cologne (again, to make it easier to apply the electrodes to your skin).

However, be sure to do the following things:

  • Eat dinner before you come for your test.
  • Shower before you come, and wash your hair with a shampoo that does not contain crème rinse. (There will also be a private shower to use the next morning before you leave, if you wish.)
  • Take your normal medications, unless your physician has instructed otherwise.
  • If someone will be picking you up the next morning, let them know that they should arrive between 7-7:30 a.m.
  • Let anyone who might need to reach you at the Center know that they can do so by calling the hospital operator at 818-409-8000 and asking to be connected to ext. 4805.

Bring the following items with you to the Sleep Center:

  • Any sleeping medication - either prescription or over-the-counter - that you take on an occasional or regular basis.
  • A list of all the medications you take and when you take them.
  • Pajamas (preferably two-piece pajamas) or a jogging suit.
  • Personal toiletries (toothbrush, toothpaste, etc.).
  • A book or other reading material (if you wish).
  • Your insurance card.
  • Insurance authorization and/or doctor's referral letter (if you have either of these).
  • The questionnaire (filled out) that you received from the Sleep Disorders Center.

Parking

Parking is free for patients who are participating in an overnight sleep study. You may park in the multi-level parking garage in front of the hospital. Be sure to take note of which level you park on. Bring your parking ticket in with you, and the Sleep Center technician will give you a parking voucher before you leave the next morning. Even if you don't receive a parking ticket, the voucher will allow you to leave the parking garage without having to pay.

Finding the Center

Enter the hospital through the main lobby, and take an elevator to the ground floor ("G") level of the main hospital building. The Sleep Disorders Center is located on the ground floor near the hospital cafeteria. There is an overhead sign in the main hallway that will guide you to the Center. When you arrive for a sleep study, please just walk in. A technician will be waiting for you.

Measurement Devices

Before you fall asleep for the night, the Sleep Center technician will attach a number of electrodes to the surface of your skin. The application of the electrodes is not painful at all. The technician might have to slightly rub very small areas of skin to ensure good contact for the electrodes. The electrodes attached to your body will include:

  • Small electrodes on your head to measure sleep.
  • A little wire under your nose to measure airflow as you breathe.
  • Two straps across your chest to measure your breathing effort.
  • An electrode on the surface of your hand to measure oxygen saturation in your body.
  • Electrodes on your legs to measure leg movement during sleep.

Although this sounds like a lot of equipment, keep in mind that it is very small and lightweight. Most people get used to it in a very short time and have no problems sleeping.

Preparing to Sleep

Rooms in the Sleep Disorders Center are not like typical hospital rooms. The bed is a normal, full-size bed (not a hospital bed), and the room's décor is similar to that in a home bedroom. You may bring your own pillow with you. If you need more blankets or pillows, the Sleep Center technician will bring them for you.

As you prepare to sleep, you can feel free to read or watch television, if you wish. Please be sure to let the technician know if you want to wake up at a specific time. Otherwise, the technician will wake you up at 6:00 a.m. You will be able to use the restroom during the night if you need to. Just signal the technician, who will help you maneuver the equipment and wires that are attached to your body.

If You Have Questions

If you have questions before your test, please call the Sleep Disorders Center at 818-409-8323 between 8 a.m. and 4 p.m., Monday through Friday. If you need to reach the Center on an emergency basis during off hours, call the hospital at 818-409-8000 and ask the operator to page beeper 19046.
