If your diagnostic sleep study indicates a breathing disorder may be affecting your sleep, your physician may order a second night for a treatment sleep study. This study monitors your sleep pattern. Leads, sensors, and belts, similar to the ones you wore for your diagnostic sleep study, are used for this study.

Prior to lights out, the tech will explain a Continuous Positive Airway Pressure (CPAP) machine. The CPAP machine creates an air “splint” holding your airway open. You will also be shown several types of CPAP masks. You can choose the one you think will be most comfortable. The pressure holding the airway open varies for each patient. Once your appropriate pressure is determined, the information is given to your physician. Your physician will order the pressure setting for your home machine.
