At Desert Smiles, Dentist, Dr. Tenney makes available the Watch-Pat 200 home test unit to screen patients for sleep apnea, and to monitor the success of dental appliances that we place. Accurate diagnosis is of up most importance for the proper and safe treatment of snoring and sleep apnea patients we care for in the Phoenix and Glendale areas. There is more than one type of apnea (obstructive, central and mixed) and each requires different treatments. In treating obstructive sleep apnea with a dental appliance such as the Somno Med MAS, follow-up testing is critical to insure the maximum possible benefits are being obtained. The Watch-Pat 200 helps us have the proper information to help make the best decisions that critically affect your long term health.

Traditionally, sleep disorders were diagnosed and treated only by primary care physicians, ENT's, pulmonologists, and neurologists. Recently, the dental profession has begun to recognize the role they can play in early detection and treatment of OSA. Modern technology makes it practical for dentists such as Dr. Tenney who are trained in dental sleep medicine, and physicians trained in traditional sleep medicine, to treat patients in close collaboration with one another. However, an accurate diagnosis can only be achieved through the efforts of properly trained practitioners. Two distinct test protocols are being used during the evaluation and treatment process.

polysomnography (PSG)

This test records a variety of body functions during sleep. It is used both to diagnose sleep apnea and to determine its severity. It is conducted overnight in a hospital or clinic where sensors attached to the body, measure 12 or more parameters including video monitoring of your sleep. Most medical insurance companies reimburse for a PSG study however the typical co-pay or deductible may range from $400-$850. It is not unusual to wait 6-8 weeks for a PSG study.

ambulatory or "at home"

This test records many of the same values of the PSG but is conducted in the privacy of your own home. Several ambulatory devices are available. The Watch-PAT200 is the only device that has exhaustive clinical research validating its accuracy. This compact device fits easily on a Velcro armband with 2 finger sensors attached. You press a button and then go to sleep. The next morning the device is returned to the office and you may receive your results in a matter of minutes. The average cost of a Watch-PAT 200 study is far less than a PSG.

why do you need a take-home sleep study?

A full and restful night's sleep is vital to one's individual health. If you have any of the symptoms related to sleep disorders, it is important to find their causes and treat them as soon as possible. While these symptoms by themselves may seem common and little cause for concern, if left untreated, sleep disorders can lead to heart attacks, strokes and even death. Other long-term physical and psychological complications can include obesity, high blood pressure, diabetes, depression, poor work performance, and strained personal relationships.

To fully understand many sleep-related problems, an overnight sleep study is needed. During the study, we monitor activity of the sympathetic nervous system and body systems such as breathing, heart rate, body movements and body position, and snoring. Problems that can be diagnosed from an overnight sleep study include the multiple types of sleep apnea, snoring, REM related problems, bruxism and different behavioral changes.

Unlike many other tests that you have to do in a hospital or sleep laboratory, the Watch-PAT 200 is an easy take home sleep test that allows you to sleep in your own bed and get the results in less than 24 hours.

what will the sleep study tell me?

The most important result is a measure of your sleep disturbance. The cause of most sleep disturbances is identified by measuring breathing, snoring, body position and REM sleep.

Sleep disturbances are reported as either the Apnea Hypopnea Index (AHI) or Respiratory Disturbance Index (RDI), which is the number of times you wake up per hour of sleep. Most of these awakenings are too short to remember as they last for a number of seconds. It is considered normal to wake up to 5 times per hour; waking 5 to 15 times is considered mild sleep apnea; 15-30 times per hour is considered moderate sleep apnea and over 30 awakenings per hour is considered severe sleep apnea and definitely indicates a sleeping problem that requires urgent intervening treatment.

The Watch-PAT 200 sleep study also reports your snoring level, the true amount of time that you slept, your heart rate, your desaturation levels, your REM (rapid eye movement of dream sleep) sleep stages and obviously the overall quality of your night's sleep.

Once Dr. Tenney receives the results of the Watch-PAT 200 test, he (in consultation also with appropriate sleep physicians and or ENT) will be able to decide what the most appropriate treatment is for you: oral appliances, CPAP or surgery. Generally, these treatments can result in a quality of life upgrade.
