Sleep Study Preparations
When you arrive at the sleep center, we'll give you a tour and orientation. You'll meet the technician who will be present during your study, and you'll see the bedrooms, which we have tried to make as homelike as possible. The rooms are equipped with extra-long double beds, recliners, digital cable TVs/DVDs, desks, fans, private baths with showers, and hair driers. After your orientation, we will set you up with the sleep study equipment, and then you'll go to sleep.
Post Sleep Study Expectations
If the sleep study takes place on a weeknight, most people get up the next day at whatever their preferred time is. They then can shower and go to work as usual. Most people don't experience much interference with their sleep. However, some people may experience poor sleep and may want to plan on taking the following day off.
Sleep Diary
You will be asked to keep a diary of your hours of sleep and wakefulness, as well record how sleepy you are and how difficult it is to stay awake during the day. By recording certain sleep-related information in the diary, patients are more likely to receive the most appropriate treatment recommendations.
The Stevens Sleep Center conducts several different sleep studies depending on the clinical situation. We are committed to providing rapid turnaround times for preliminary reports and completed studies. All sleep studies are reviewed by one of our medical directors.
For children, please call the Stevens Sleep Center to speak with a medical director. We may be able to evaluate the child directly, or we may refer you to a sleep center that specializes in handling children.
Full-night or Split-night Polysomnogram
The polysomnogram (PSG) records EEG activity, eye and chin movements, air flow, snoring, oximetry, and leg kicks. Physicians may order a full-night PSG, which lasts eight hours, or a split-night study, which includes PSG followed by continuous positive airway pressure (CPAP) therapy. End-tidal carbon dioxide monitoring is also available.
Multiple Sleep Latency Test (MSLT)
The MSLT assesses the severity of daytime sleepiness in patients. Patients are given several nap opportunities during which sleep latency and sleep-onset REM are assessed.
Maintenance of Wakefulness Test
This test measures a patient's ability to stay awake and is used to test drivers, truckers and pilots. This is a standard test in the driving and aviation industries.
