Types of Sleep Tests
A polysomnography (PSG) is commonly called a sleep study. This recording is a safe, non-invasive, painless technique to monitor breathing, oxygen levels, heart activity, body movements, and sleep quality. Each patient has a private room with a home-like decor including television, reading light, and private shower facilities. A technician remains in attendance (outside of the room) throughout the night monitoring the test.
- Because testing is performed at night in most cases, you will not need to miss a day of work or school.
Multiple Sleep Latency Test (MSLT):
The Multiple Sleep Latency Test may be performed on the day following an overnight sleep study. The MSLT is a series of nap opportunities to measure sleepiness and/or to diagnose narcolepsy. This test is generally performed to determine causes of severe sleepiness when no other abnormality has been identified during the overnight testing. During this test several nap opportunities are provided with less extensive monitoring than the sleep study. The patients are able to be dressed and move around the Sleep Center between naps.
Overnight sleep studies are also performed in children over one year of age. This testing requires specialized monitoring, data review, and interpretation adjusted for the pediatric age group. Bedtimes are adjusted to fit the child's schedule. Our Sleep Centers provide a child-friendly environment and a comfortable place for the parent/guardian to stay with their child.
