Here are the types of sleep studies performed at Valley Sleep Center.


Sleep Consultation

A sleep consultation is a 15 minute appointment with a Board Certified sleep physician who will review your medical history, go over any signs and symptoms you may be experiencing, and order the appropriate sleep test that you need.


The polysomnogram is often the initial sleep test conducted because it can be used to diagnose a variety of sleep disorders including sleep apnea. Prior to the test, sensors are attached to various points on the body to capture the required data. Although the sensors are connected to wires and attached to monitoring equipment, most people do not have issues falling asleep during the test.

Multiple Sleep Latency Test (MSLT)

The Multiple Sleep Latency Test (MSLT) is generally ordered after a polysomnogram has been completed. This test is conducted during the day and is used to measure day time sleepiness. Used to diagnose parasomnias like narcolepsy, the test is conducted several times over the course of a single day.

Maintenance of Wakefulness Test

The Maintenance of Wakefulness Testing tests how well you can stay alert. Like the MSLT, this test is conducted during the day and can take most of the day. Participants are asked to remain awake during the entire testing period and their ability to remain awake while sitting still and staring straight ahead is measured.


At Home Apnea Screening

Home apnea screening utilizes a small testing device that monitors your breathing, oxygen levels, and snoring to assist in screening for sleep apnea.

This Home-Based Portable Monitor Test differs from a polysomnogram as it monitors less of the body’s activity, is only used in adults with one sleep disorder, and not everyone is a candidate for a home sleep test. The testing equipment and information on how to perform the test will be provided by a sleep center professional upon picking up the equipment.


Client Reviews

"I was especially impressed with Andrew the Respiratory Therapist who reviewed my study with me and answered my questions. Andrew thoroughly explained everything about the Cpap machine-from start to finish. I never felt rushed and was assured I could contact him with any additional questions or needs. Andrew told me he would follow up with a call in a week and he did. I believe this center performed the study appropriately and the added benefit of having Andrew teach me about the machine and what to expect was a bonus."

"I recommend them highly!! I took my 2 year old daughter for a sleep study and was very impressed. Our sleep technician was amazing with her, very patient and kind. The DVD we brought to watch while getting her hooked up got stuck in the TV and they vowed to return it. We got a call the next day checking on our daughter and saying how sweet she was, they mentioned the DVD. Several days later, we received the DVD plus a new copy of the Lion King with a nice note. They are very good at what they do and if they can make a 2 year old feel at ease, they can probably do the same with anyone!!"
