In-Lab Sleep Study (Polysomnogram)
A Polysomnogram (PSG) is an in-lab overnight sleep study in which patient
is instructed to spend the night in the sleep disorders center where our
technologist will apply sensors and monitor bodily functions during sleep.
The health care providers usually order this test for patients with symptoms
of sleep disorders which include but are not limited to: snoring, sleep
apnea, insomnia, excessive daytime sleepiness and restless legs.
What to Bring
- Your physician order (your physician may have already sent this to us)
- Personal ID / Insurance Card
- Medication to take at bedtime if prescribed and instructed by your care provider.
- A completely filled-out Sleep Questionnaire that our sleep center mailed to you.
How to Prepare

is free of any oil, excessive sprays or other hair products. Gentlemen
should come clean-shaven, unless you normally wear a beard.
- If possible, avoid taking any naps during the day of your sleep study.
- Do no use any caffeine-containing products (i.e. coffee, tea, cocoa, chocolate)
after 12 noon on the day of your sleep study. (Decaffeinated products

sleepiness or plan to take a sleep medicine,
make sure someone drives you to the Center and picks you up after testing. If this is not possible, call us at (985) 230-6083, and we will help
you find a solution.

you directly to your room.

bed, a recliner and a private, a full bathroom.

screening form with you. He/she will explain the procedure that your doctor ordered.
- During the setup, you will have disc-like electrodes applied to your scalp
using a conductive paste to hold them down and a few body sensors applied
to measure breathing and body movements.
- At the start of the test, a technologist will turn off the light in your
room to allow you to fall asleep. If you are here for a sleep apnea treatment
therapy, the technologist will turn on a CPAP machine at this time.

you need assistance at night.
