About Your Sleep Study

The sleep test is a completely painless outpatient procedure and is monitored by a registered polysomnographic technologist. Sleep study tests involves the use of electrodes and elastic belts to monitor your breathing patterns, limb movements, heartbeat, oxygen levels and brain waves. Electrodes are applied with either a paste or adhesive and are easily removed in the morning. This test provides key data about your sleep and any sleeping disorders, including brainwave patterns, muscle tension levels, eye movements, heart rate, breathing patterns and the amount of oxygen in your blood.

If you are known to experience brief pauses in your breathing when asleep, known as sleep apnea, you may be asked to try Continuous Positive Airway Pressure (CPAP) therapy, which is a device that gently blows air into your nasal passages to keep the airway open and breathing stable when you sleep.


Study results
The results of your study will be interpreted by a sleep lab physician and a specialty trained sleep disorders physician. Results and recommendations will be sent to your primary care physician. A complimentary breakfast is provided.

Tests performed
Tests that may be performed include: 

• Polysomnogram (sleep study) –The polysomnogram provides key data about your sleep disorder by monitoring brain wave activity, eye movements, blood oxygen levels, respiration, heartbeat, airflow through the nose and mouth, and the movement of muscles and limbs. 
• Continuous Positive Airway Pressure (CPAP) Titration –A sleep study in which a patient wears a mask that delivers air to help maintain normal breathing while asleep. 
• Split Night Study –A sleep study in which CPAP is placed on the patient halfway through the study if the patient is found to have sleep apnea. 
• Multiple Sleep Latency Test (MSLT)– Patients may be asked to stay for an MSLT the day after nighttime testing. The MSLT measures daytime sleepiness and is valuable for diagnosing narcolepsy and excessive daytime sleepiness.
• Maintenance of Wakefulness Test (MWT) –This test measures a person’s ability to maintain wakefulness.
