What's An EEG?
An EEG is a test that measures and records the electrical activity of your brain. It’s used to diagnose seizure disorders, such as epilepsy
When you arrive for your sleep study, a Registered Polysomnographic Technologist or Respiratory Therapist will be at the site to greet you and show you to your room. After you make yourself comfortable, your technologist will take a brief history, explain the study process, and answer any questions you may have prior to applying the sensors. This process is completely painless and generally takes about 40 minutes to make sure everything is placed correctly.
What to Expect?
First, the technologist will use stickers to affix leads on your chest and abdomen.
Next, your head will be marked and measured with a paper ruler and a grease pencil. This is done because each electrode needs to be placed in a precise location in order to accurately measure your brain waves. Once this is complete, a skin prep jelly will be applied to clean your scalp for the electrodes. This jelly removes any excess oils or skin cells in order to obtain a clear reading of your brain waves.
Lastly, the electrodes are placed on the surface of your scalp with a small amount of paste. The prep, paste, and tape are hypoallergenic.
After all the sensors are applied and checked, the technologist will do a series of tests to obtain a baseline of your brain activity. These tests may include fast, shallow breathing (hyperventilation), as well as strobe light testing (photic stimulation). When these tests are done, you’ll be asked to lie still with your eyes closed and try to fall asleep.
Your technologist will monitor your testing throughout the study and will be available to answer questions and ensure you’re comfortable.
Once your study is complete, the technologist will remove the electrodes and leads. Any remaining paste or marks can be easily washed out using warm water and shampoo.
At your follow-up appointment, you’ll receive your EEG results and discuss them with your provider.
Preparing for Your Sleep Test
Set Time Aside
Plan to be at our sleep center for approximately 2-3 hours.
Wash and Dry Your Hair
Wash and dry your hair thoroughly but do not use conditioners or other hair products.
Remove any hair weaves or extensions. We cannot do testing if you have either of these.
What Should I Wear?
Wear comfortable, loose-fitting clothing to relax in throughout the duration of your test.
Bring – and take – all of your normally scheduled medications unless otherwise directed by your doctor or the staff at Sleep Insights.
Special Requirements and Guests
Guests are not allowed to stay overnight with patients other than for specific medical reasons (e.g. parent with a child, caregiver for patient with special needs). Arrangements for caretakers must be made with advanced notice and with prior permission from their provider. Anyone accompanying a patient to their sleep test who isn’t an approved caretaker must remain in the waiting room.
Smoking, vaping and the use of alcohol are not permitted in the building or on the premises at any time.
Cancellations must be made by at least 12 noon the day before your study, or if your study is on a Saturday or Sunday, by noon on the Friday before.
Failure to show up for your scheduled sleep study will result in a $100.00 no-show charge.
