What To Expect:
After arriving at the sleep center, the technician will take you to your private comfortable room, which is designed like a normal bedroom. You will have time to change into your comfortable night clothing and place your belongings in the cabinets. Subsequently, you will be taken to the prep room where several different electrodes will be placed on your body to monitor your sleep. Typically, it takes twenty to thirty minutes for the setup process. After that you will return to your room and relax until you fall asleep. You may read a book or watch TV. You will be able to communicate with your technician at any time via the sensitive microphone. Your sleep will be monitored very closely for the entire night by the technician from an outside computer terminal. You may use the restroom if needed. In the morning, all the electrodes will be removed from your body.
When Will I Know the Results?
The sleep disorders specialist will review the entire data with the help of a computer and prepare his detailed report. This will be sent to your physician or will be communicated to you. Typically it takes a few days for you to receive the report as the study consists of approximately 1000 pages of data that must be reviewed carefully.
Please do not forget to pick up our patient education and information brochures on a variety of sleep-related subjects.
