What if an Overnight Sleep Study is Recommended?
Overnight Sleep Studies
As part of the process to determine if you have a sleep disorder, you may be scheduled for an overnight sleep study. If you need to stay overnight at the HSHS St. Joseph’s Hospital Center for Sleep Medicine, the following information has been designed to help you prepare for your stay. You can also download a brochure with all of the information here or take a virtual tour before your visit.
Please read all of the following before your appointment, and download and print this Sleep Center Packet and bring it with you when you come in for the study.
How should I prepare for my visit?
Be aware that there may be a short wait before a sleep technician starts your study, so feel free to bring something to occupy your time. A TV is provided. We can offer you water, but if you want anything else to drink, please bring it with you, as well as any snacks you may want before bed.
To prepare for your visit:
- Take a bath or shower* and shampoo your hair prior to coming for your test.
- Ladies, please avoid chemical enhancements (hair color, permanent, etc.) or adding hair pieces prior to testing.
- Gentlemen, please shave before you come in for testing. This does not apply to men with full beards or mustaches.
- Eat a normal meal prior to your arrival at the SJH Center for Sleep Medicine.
- If the day of your test is one that you do not work, keep active during the day so that you will not have trouble falling asleep.
- Refrain from using any styling products prior to arrival.
- Remove any nail polish prior to arrival. You will have a pulse oximetry monitor on your index finger.
- Leave excess money or valuables at home.
- Bring your insurance card.
Please do NOT:
- Take any naps the day of your visit.
- Consume any alcohol or caffeine within 12 hours of your appointment.
*If you want to take a shower before you leave in the morning, we have showers available in each suite.
What should I bring with me?
- An overnight bag including pajamas (or comfortable clothes for sleeping) and a change of clothing.
- Pillows will be provided to you; however, you may bring your own pillow if you prefer.
- Personal toiletry items (toothbrush, toothpaste).
- Medications you may need (including any sleep aids you normally take), along with a list of all the medications you’re currently taking. A refrigerator is available for any medications needing refrigeration. DO NOT STOP ANY MEDICATION unless you are instructed to do so by the physician ordering the study.
If you are currently taking sleep aids, please bring them but do not take them until the technician tells you it is time for bed. Notify the technician of any medications – including over-the-counter medications – that you take
Where should I park?
Parking is best if accessed from IL-60. The main entrance and Medical Office Building will be closed when you arrive for an overnight sleep test, so please enter the hospital at the Emergency Department/PrimeCare entrance and register at the front desk. Download a map
Are sleep studies covered by insurance?
Sleep studies are covered under most medical insurance plans, although deductible and percent of coverage vary. Detailed questions about coverage should be directed to your insurance company; however, we will verify coverage prior to your visit. Any cancellation fees you incur are not covered by your insurance provider.
What can I expect the day of my sleep study?
You’ll sleep overnight in a private room while a trained technologist monitors you. Every room is individually climate-controlled. If you find your room to be too hot or too cold, please let the technician know.
Before beginning the study, our sleep technician will provide you with helpful information. He or she will also be available throughout the night to assist and answer any questions.
The technician will place electrodes on your body. These electrodes are painless, but due to the adhesive used with these electrodes, most patients prefer to shower before leaving in the morning. During your sleep study, you will be constantly monitored by our specially trained sleep technicians – both through these electrodes and on a video screen – for your safety.
What happens after my sleep study?
Your sleep study will conclude at approximately 6 a.m. If you need to leave earlier to get to work, accommodations may be made. Simply notify your sleep technician when you arrive.
St. Joseph’s Center for Sleep Medicine will provide a written report of your sleep study to your referring physician. Either the Sleep Center or your referring physician will schedule you for a follow-up visit to receive your results and recommend treatment in person.
What if I need to cancel or reschedule my sleep study?
If you are unable to keep your appointment and need to cancel, please call (618) 651-2736. If we don’t answer, please leave a message on the voice mail.
