Procedures & Services

Salem Sleep Medicine provides the following services.

Polysomnography (Overnight Sleep Study)

Polysomnography is used to diagnose, or rule out, many types of sleep disorders including narcolepsy, periodic limb movement disorder (PLMD), REM behavior disorder, parasomnias, and sleep apnea.

It is often ordered for patients with complaints of daytime fatigue or sleepiness that may be caused by interrupted sleep. Although it is not directly useful in diagnosing circadian rhythm sleep disorders, it may be used to rule out other sleep disorders.

Continuous Positive Air Pressure Titrations (CPAP)

This is an extensively used, successful treatment for obstructive sleep apnea. It consists of a machine connected to the patient via a hose and nasal mask. Every night the patient sleeps with the CPAP machine.

The machine is programmed to deliver a specific air pressure for that patient as determined by the titration study. The constant stream of air “splints” the throat and keeps it from collapsing and obstructing airflow.  It prevents the apneic events and snoring associated with obstructive sleep apnea and ensures that the patient reaches the deeper stages (stage 4 and REM) of sleep that result in a restorative night’s rest.

Ambulatory Sleep Study and Screening

This is a take home study where the patient is given a monitor to take home and use that records various data that can be downloaded and evaluated in our office.

Mean Sleep Latency Test (MSLT)

The MSLT is the primary test for the diagnosis of narcolepsy. This test assesses two major components of narcolepsy: hypersomnolence and SOREMPs (Sleep Onset Rapid Eye Movement Periods), which occur in narcolepsy but are otherwise uncommon.

The mean sleep latency, or time to sleep onset, provides evidence for hypersomnolence. The test uses an EEG to record sleep onset during normal waking hours.

Maintenance of Wakefulness Test

The Maintenance of Wakefulness Test (MWT) is used to measure how alert you are during the day. It shows whether or not you are able to stay awake for a defined period of time. This is an indicator of how well you are able to function and remain alert in quiet times of inactivity.

The test is based on the idea that your ability to stay awake may be more important to know in some cases than how fast you fall asleep. This is the case when the MWT is used to see how well a sleep disorders patient is able to stay awake after starting treatment. It is also used to help judge whether a patient is too tired to drive or perform other daily tasks.

PAP Machines and Supplies

We vend PAP machines, masks and supplies to patients with commercial insurance plans. Our experienced technologists will set you up with your new machine and help you acclimate to the therapy, provide you with mask fittings to ensure you have the best fitting mask, and give you on-going support.
