Testing and sleep studies

All sleep evaluations and testing are provided following a referral from your primary care provider. If providers need a copy of the referral form for the Sleep Health Center at Alice Peck Day Memorial Hospital, they should call or email us directly. Patients can avoid taking time off work by having their sleep study done overnight. The Sleep Health Center accepts most major insurance plans, and our staff can help you with your insurance questions, including pre-certification and verification.

You might experience the following types of sleep studies or tests in our Sleep Health Center:

Sleep study or polysomnograph

An overnight study of your sleep conducted at our Sleep Center that diagnoses the type of sleep disorder you may have. The test monitors your heart rate, breathing rate and rhythm, eye movement, muscle activity, brain activity, blood oxygen level, and airflow.

Continuous positive airway pressure (CPAP) trial

This trial is for those who have already been tested and diagnosed with sleep apnea. During this test patients will wear a CPAP mask to keep the airway open. At optimal airway pressure, the patient will no longer snore or have periods of sleep disordered breathing. Surgical options are also available if physical corrections are needed. Nonconventional methods, such as positional measures and oral appliances, are also available

Multiple sleep latency testing (MSLT)

Used to determine how tired patients are during the day. During this test we look for how quickly subjects fall asleep and which stage of sleep they are able achieve.

Multiple wakefulness test (MWT)

Determines how likely patients are to stay awake in a sedentary situation.


Determines circadian rhythm (sleep wake cycle). Patients wear a wristwatch-type device for a period of 2 to 3 weeks. During this time, the device records your wrist movements, which are inactive during sleep.
