Sleep Disorder Diagnosis

Ridgeview offers three types of testing: overnight sleep study/polysomnogram (PSG), home sleep tests and multiple sleep latency tests (MSLT).

Overnight sleep study/Polysomnogram (PSG)

To aid in diagnosing a sleep disorder, you will need an overnight sleep study called a polysomnogram (PSG). During the sleep study, polysomnographic technologists attach a variety of devices to you to observe your sleep patterns. The devices monitor brain waves, heart rate, eye movements, airflow and leg movements.

Sleep studies are conducted in the Ridgeview sleep lab on the Waconia campus. We have four uniquely equipped sleep rooms, warmly decorated to simulate a hotel suite for optimal sleep comfort. All team members working in the sleep lab are registered polysomnographic technologists.

Home Sleep Test

Depending on your existing medical conditions and symptoms, you may have the option of participating in an at-home sleep study. For the at-home test, a portable device is used to test specifically for sleep apnea and cannot detect other sleep disorders. A sleep technologist will instruct you to use the device. You may need to sleep with the device for one to three nights, depending on the device your doctor orders. When your home study is completed, you return the device to the sleep lab. Note: Not everyone qualifies for the at-home test, and your insurance company may have specific guidelines.

Ravi Vaela, MD – Ridgeview’s sleep center physician –will discuss the different testing options for sleep apnea with you. Following a sleep study, you are scheduled to meet with Dr. Vaela for a follow-up consultation. He reviews the results of your study and develops a treatment plan. Treatments may include Continuous Positive Airway Pressure (CPAP), oral appliances, surgical procedures or medication.

Multiple Sleep Latency Test (MSLT)

You may require a Multiple Sleep Latency Test (MSLT), which evaluates your level of sleepiness.

PSGs and MSLTs are performed by highly trained technologists, who will monitor and record your brain waves, eye movements, oxygen saturation, respiratory effort, airflow and leg movements. PSG and MSLT results are reviewed by Dr. Ravi Vaela, and shared with you. A formal analysis report, including your diagnosis and treatment recommendations, is forwarded to your referring physician. Some of the treatments may include Continuous Positive Airway Pressure (CPAP), oral appliances, surgical procedures or medication. CPAP equipment can be purchased or rented through Ridgeview Home Medical Equipment, located at 141 W. First Street, Suite 300, in Waconia.

To participate in a sleep study at the Ridgeview’s Sleep Lab, you must be 16 years or older and referred by a physician.
