There is a very effective, widely accepted treatment for sleep apnea called CPAP. A bedside device gently delivers pressurized air through a small mask or nasal pillow system. This pressure acts like an air splint to keep your upper airway open and help prevent apneas.

This treatment doesn’t involve drugs or surgery and helps hundreds of thousands of people all over the world to enjoy healthier sleep and healthier life. Many experience the benefits

Home Sleep Testing

Home sleep studies are used for patients whose insurance carriers require the study and for patients with physical limitations. After receiving instructions from a technician, the patient takes the testing device home. The device fits around the head like a headband and sits on the forehead. It monitors oxygen levels, heart rate and can tell if the patient is awake or asleep and collects data during the study. After the study, the patient returns the device to the Center so the collected data can be retrieved from the device and interpreted by a technician.
