Sleep Medicine


Comprehensive Sleep Evaluations and Follow-Up Care
Nationally Accredited by the American Academy of Sleep Medicine

It Shouldn’t Be Hard Work to Get a Good Night’s Sleep.

Nearly 70 million people in America suffer from a sleep problem. Up to 80% of sleep apnea sufferers have yet to be diagnosed. Untreated sleep disorders and sleep deprivation are estimated to cost Americans 100 billion dollars each year. An estimated 1,000,000 police-reported accidents, 1,550 fatalities, and 71,000 injuries were caused from drowsy drivers.

Normal sleep is a restorative process that allows a person to live a healthy, productive life. Suffering from a sleep disorder can be dibilitating. Studies have shown links between sleep apnea, heart disease, diabetes, and other metabolic disease.

The Oregon Clinic's Sleep Medicine Specialty has a nationally prominent team of pulmonary physicians and neurologists with expertise in evaluating and treating patients with a wide variety of sleep related illnesses and disorders.




We work as a team to provide continued care and understanding of these illnesses, including offering on-site diagnostic and imaging services for creating a treatment plan and diagnosing these health issues. We are committed to staffing the sleep center with well-qualified, dedicated staff that maintain the highest level of patient care and physician-directed treatment.

In a manner consistent with the recommendation of the American Academy of Sleep Medicine, all patients referred for sleep testing will be provided a comprehensive sleep evaluation by one of our physicians, followed by appropriate testing and treatment, which may include polysomnography.

How can I sleep with all of the sensors on?

Most people sleep reasonably well. The doctor is looking to obtain a sample of your sleep pattern. Your movements will not be inhibited and you will be able to change positions if needed. We strive to make your experience as comfortable as possible.

Why do I have to see a doctor before I have a sleep study?

All new patients are scheduled to see a physician prior to any tests being ordered. This ensures that each patient is fully evaluated for any sleep disorders that may be occurring. At the initial consultation, it gives you an opportunity to get acquainted with our office, the location, and tour the sleep center. All of these activities will help you feel more comfortable during your sleep study.

What time will the study be over?

Typically the study will end between 6am to 7am. In certain circumstances, special accommodations are made for people who sleep during the day or work late into the night. This should be discussed with your sleep physician and our scheduling team so that we can arrange to meet your specific situation.

How long will it take to get the results of my sleep study?

Follow up appointments are generally scheduled with your sleep physician or nurse practitioner one week following your sleep study. In some circumstances your provider may call you by phone to go over the results of your study. If you don’t receive results within 10 days, call the Sleep Center.

Why do I need to have another sleep study?

Often times a second sleep study is ordered by your physician so that a titration with CPAP or BPAP can be performed. Although some individuals will have what’s called a split night study during which the second half of the night CPAP is applied. If you do not have a split night study it does not mean that you don’t have sleep apnea--it simply means that the physician needs to interpret the study before making further recommendations.

Is the sleep study covered by insurance?

Sleep studies are covered by insurance. Individual deductibles and coverage varies. You should call your insurance company directly and ask what your specific plan coverage is. We will verify insurance benefits and obtain authorization if necessary at the time your sleep study is scheduled.
