The Brown Medicine Sleep Center, located at Brown Medicine Patient Center is accessible by car and public transportation. If you are found to have moderate or severe obstructive sleep apnea, then CPAP or BiPAP titration will begin during the second half of the night. This is a combination overnight sleep study and positive airway pressure titration. Once you are asleep, you will be monitored during the first half of the night to confirm that you have sleep apnea. This is termed a “baseline” period. In some cases, CPAP does not work well for a patient’s condition, or another mode of therapy is needed to fully control the sleep disordered breathing. In this case, your clinician may order a similar test, for example a BiPAP or Bilevel Titration study or adaptive servo ventilation (ASV) study. During the test, the technologist will help you find the best mask/interface and adjust the therapy, therefore the settings are personalized for you. The most common titration study is Continuous Airway Pressure (CPAP) therapy. CPAP is the first line therapy for treating most sleep-related breathing disorders. This is a highly effective therapy, whereby a mask is worn over the nose during sleep. Pressure from a small medical air compressor delivers air through your nasal passages and into the airway under gentle pressure, keeping it open and allowing you to sleep and breathe normally. This test is performed if you are found to have obstructive sleep apnea, central sleep apnea, or hypoventilation with hypoxemia. This test cannot be performed until one of those diagnoses have been confirmed. Once you are diagnosed, you may need a PAP titration study before you can begin treatment.Ī PAP titration study is an in-lab sleep study used to determine the best settings for treating your sleep disordered breathing. PAP Titration Study (Positive-Airway-Pressure Titration): You are woken up at approximately 5:30 AM. A technician watches as you sleep via a discreet camera. This test is performed to diagnose sleep disorders such as sleep apnea and periodic limb movement disorder. The test will begin once you are asleep. As you sleep, non-invasive, flexible equipment attached to your head and body monitor your brain waves, breathing, and movement. The sleep technologist will confirm this before the study. The following is an explanation of the tests that are performed at the Brown Medicine Sleep Center. You will be scheduled for one (1) or possibly two (2) of these tests. Your provider will inform you of what test(s) you are having performed at the time of your initial evaluation. Please allow 2 weeks to complete this process. Once the physician receives the results, the results are copied into a formal sleep study report and forwarded to the physician who referred you to our lab. The technicians will stay in a separate control room to watch a computer monitor record your sleep information.Īfter a full night’s sleep is recorded, the data will be tabulated by our scoring technologist and provided to a physician for interpretation. Once the sleep sensors are applied, you may read or watch TV in bed until you are sleepy, according to your usual routine. Depending on the physician’s orders, patients may be given therapy during the course of the study, which may include medication, oxygen or positive airway pressure therapy delivered through a device called CPAP or BiPAP. The technologist will go over any questions you may have prior to the study. The sleep technologist will review your patient questionnaire and ensure that all the information needed for the test is up-to-date and accurate. Bathrooms/showers are located outside of the patient sleep room. Your sleep room is set up similar to a hotel room, which includes a full-size bed with 2 pillows, a recliner chair, TV/cable/WiFi, personal temperature control unit, bottled water/snacks and personal storage chest. Once you have been greeted and identification has been verified, you will be escorted to your sleep room. Upon arrival for your sleep study, you will be greeted by the sleep technologist.
