Sleep Study Preparation
Before a sleep study can be scheduled, a complete physical examination by your referring doctor may be required. Your insurance may require pre-authorization, and if so, Chicago Sleep Center will help.
Sleep studies require an overnight stay at one of our sleep centers. Our centers offer various testing room environments from the standard room to luxury hotel rooms. We also offer sleep studies in the comfort of your own home.
What to Expect During and After the Study
The sleep study consists of monitoring airflow from your nose and mouth, heart rate, leg movement, muscle movement, brain waves, oxygen levels, and eye movement.
Electrodes will be placed on your scalp, chest, and legs by a trained sleep technician. During the sleep study, no one will watch you sleep. Your sleep will be monitored by computers. The entire study is outpatient and is painless.
The study will be interpreted by a physician board-certified in sleep medicine. A full analysis will be submitted to your physician and will include any necessary information to help treat insomnia, obstructive sleep apnea, snoring, etc. Your physician will advise you on all available options.
Common Sleep Study Questions
What is a sleep study and why do i need it?
The all-night Sleep Study (Polysomnography test from 9:00 p.m. to 5:30 am the next day) is a non-invasive recording of multiple body functions during sleep. The Polysomnography will record your brain wave patterns (EEG), muscle movements and movements of your eyes, the amount of oxygen, nose, mouth, and abdominal breathing, your leg movements and your heart rate in sleep. These functions are analyzed separately and in their interactions.
An overnight Sleep Study is a painless and very important test to diagnose disorders related to sleep, such as stop breathing in sleep, snoring, awakenings or difficulties falling back to sleep, heart irregularities, muscle pain, bad dreams, unusual behavior in your sleep and many others (there are 83 sleep disorders identified). A Sleep Study test is crucial in helping to develop the right treatment.
What is a CPAP Titration study?
For patients with a confirmed diagnosis of Obstructive Sleep Apnea (OSA), a CPAP Titration sleep study will be performed to calibrate Continuous Positive Airway Pressure (CPAP). The CPAP device is a machine with a humidifier, which produces air that flows through a fitted mask into the nose or mouth with a specified pressure. Titration means careful and precise measurement of the necessary pressure. Currently, CPAP is the most common way to treat and manage sleep-related breathing disorders.
Why am I having a Multiple Sleep Latency Test (MSLT)?
For people who have excessive daytime sleepiness and fatigue, a Multiple Sleep Latency Test (MSLT) is a necessity. This test objectively measures the level of sleepiness and is performed in the morning, always following the Sleep Study. The MSLT consists of four to five 20 minute naps followed by periods of alertness.
Will someone watch me sleep?
No one will watch you sleep. Cameras and sensors are present to detect your position and snoring.
How do I confirm or cancel my appointment?
One to two days before your test, our staff will call you to confirm you appointment and ask if you have any additional questions. NOTE: We ask that you contact our office at least 24 hours prior to the test if you need to CANCEL or reschedule.
What about my regular medications?
Take all the medications that you usually take at the prescribed times. Bring any nighttime medications or medication for the next morning with you. If you are unsure please consult with your doctor.
Will you give me medication if I can't sleep?
No sleeping pills will be given to you during your sleep study, however If necessary, your doctor can prescribe you something or recommend something over the counter to take.
What if I need special accommodations?
Inform the person scheduling your sleep study, if you have any special needs, medical conditions or allergies, diabetes, asthma, etc.
What if I have a preferred time to sleep?
Inform the scheduling staff about your preferable bedtime and wake up time and we can try to accommodate outside of our normal scheduling times.
What to bring and what not to bring with you for your sleep study
- Insurance card(s) and ID
- Bring your pajamas/nightgown, toothbrush, toothpaste, slippers and socks.
- Please, NO hair spray, gel, conditioner or lotion prior to the test.
- Ladies, please NO heavy make-up, nail polish or artificial nails.
- Gentlemen, please, try to shave your face before the test. It will be easier to attach the electrodes and provide more accurate recordings.
Will I be able to adjust my sleep positions with the sensors connected?
Most patients get adjusted to the sensors and wires easily. You will be able to move around in sleep and adjust your sleeping position. Please note that you will be asked to spend some time on your back. In the morning all electrodes will be removed. You will have an opportunity to comment on the technician and other issues of the study by completing the Morning Report form.
When will my referring doctor get the results?
Your doctor will receive the results of the Sleep Study, interpretations and recommendations, within 5-7 business days by fax. We encourage you to contact your Doctor for a follow-up appointment.
