Diagnostic Testing Services

At Sleep HealthCenters, we offer the latest diagnostic technology and highest level of comfort and care to ensure a successful outcome for the patient.

In our diagnostic testing facilities, we can perform a variety of sleep studies designed to identify each patient’s specific sleep disorder.  The tests include overnight physiologic studies called polysomnograms (PSGs).  The multiple sleep latency test (MSLT) and the maintenance of wakefulness test (MWT) are daytime studies that quantify sleepiness and diagnose disorders of excessive sleepiness.  Treatments for sleep and breathing disorders such as sleep apnea, including the administration of CPAP/BiPAP and nocturnal oxygen, are frequently initiated during a PSG.  All our tests are performed by highly trained technologists.

A standard PSG 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

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; private lavatories with shower, and a continental breakfast so that patients can undergo a full sleep diagnostic procedure, wake up and start the day with minimal disruption to their lives.
