Overnight Sleep Study

Also called a Polysomnogram or PSG, a standard sleep study in one of our centers includes the following:

* EEG (electroencephalogram) – monitors brain activity to document sleep stages
* EOG (electrooculogram) – measures eye movement
* EMG (electromyogram) – measures muscle activity for monitoring muscle tone as well as body movement, especially limbs
* EKG (electrocardiogram) – monitors heart activity
* Respiratory Airflow – measures airflow from nose and mouth to document respiratory disturbances
* Respiratory Effort – monitors chest wall and abdominal movement to help determine specific respiratory disturbances
* Pulse oximetry – measures the oxygen saturation level to distinguish changes during respiratory events
* Snoring – monitors vibration of throat to determine snoring episodes
* Body Position – monitors the effect of sleep position on sleep and breathing
* Other parameters as determined by physician

Treatments for sleep and breathing disorders such as sleep apnea, including the administration of positive airway pressure (PAP) and nocturnal oxygen, are frequently initiated during a PSG.

During a sleep study, the technologist is in constant video and audio contact with the patient, providing a safe, supportive environment with minimal anxiety. Our diagnostic suites have been designed to promote a relaxing atmosphere and a pleasant patient experience. We offer full-size beds and private bathrooms so that patients can undergo a full sleep diagnostic procedure, wake up and start the day with minimal disruption to their lives.
Pediatric Sleep Study

Also called a pediatric polysomnogram or PSG.

We have very comfortable accomodations designed for children. Parents can sleep in the room with the child or in a separate room depending on the child's needs. Our technicians are specifically trained in polysomnography for children.

* Overnight Sleep Studies
o Diagnostic polysomnogram
o Overnight therapy
* Bi-level PAP
* Supplemental oxygen
* Multiple Sleep Latency Test (MSLT)

Mulitple Sleep Latency Test

The multiple sleep latency test (MSLT) is the standard way to quantify sleepiness and diagnose disorders of excessive sleepiness. An overnight diagnostic sleep test called a polysomnogram (PSG) is required the night prior to the daytime MSLT. After the PSG is complete, a series of nap tests are spread out over the following day.

After being asked to try to fall asleep for each nap test, sensors on the head and chest record your brain wave activity, eye movements, muscle contractions and heart activity to accurately detect if you fall asleep.

The information we collect during your study is reviewed and analyzed by our sleep specialists.

Maintenance of Wakefulness Test

The MWT evaluates the person's ability to stay awake during the day. Normally an overnight sleep study [PSG] is performed the night prior to the daytime MWT.

Following the overnight sleep study patients are continually monitored during the day. Results are then analyzed.
