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 or queen sized beds in private bedrooms and most locations offer a light breakfast (such as oatmeal or breakfast bars) so that patients can undergo a full sleep diagnostic procedure, wake up and start the day with minimal disruption to their lives.
