Center for Sleep Medicine
FAQs / During The Sleep Study
What happens when I arrive at the sleep center?
The study usually begins in the late evening and ends about 6:00 – 6:30 a.m. Once you arrive at the center, a sleep technologist will welcome you and show you to your private bedroom. The technologist will ask you to fill out some forms and answer any questions you may have. As part of your orientation, you may be asked to watch a video that will explain the process.
Will I have a private bedroom?
Yes, sleep study bedrooms are private. The bedrooms have private bathrooms with showers. Each room has an independent control for heating and cooling. Your sleep technologist can help adjust the room temperature to meet you needs.
How do I get ready for the study?
After you change into your sleepwear, the sleep technologist will place a number of non-painful sensors (also called electrodes) on your head, chest area and legs. The areas where the sensors will be attached are cleaned and the electrodes are attached with special gels and paste. (The gels and paste are harmless, however, if you have sensitive skin, please alert your sleep technologist prior to attaching the electrodes.) Elastic belts with sensors will be placed around your chest and abdomen. Airflow sensors will be placed under your nose and a finger clip will be applied to monitor your oxygen levels. All of the sensors will be connected to a small portable box that transmits signals to the sleep monitoring and recording equipment that is in a nearby control room.
Will I be able to sleep with so many things attached to me?
You may find it a bit strange at first, but most people do not find it uncomfortable or an obstacle to falling asleep. We will make every effort to ensure that you are as comfortable as possible. If a problem arises, your sleep technologist will make adjustments. The bedroom has an open intercom that will enable you to communicate with your technologist at any time.
What if I need to go to the bathroom during the study?
If you need to use the bathroom during the night, you can call your sleep technologist on the intercom for assistance. They will temporarily disconnect you from the sleep monitoring equipment.
What happens while I’m sleeping?
The lab is a busy place and there will be other patients being monitored during the same evening. The sleep technologists remain awake in the control room throughout the night analyzing the information being collected while you sleep.
Will I be treated for my sleep disorder while I’m there?
For certain patients with Obstructive Sleep Apnea (OSA), the sleep study may include the beginning of a treatment called CPAP (Continuous Positive Airway Pressure). After you are asleep for a period of time, the sleep technologist will be able to determine if you have evidence of OSA. If you have evidence of OSA, CPAP treatment may be started during the night. During your orientation, this will be thoroughly reviewed, and you will have plenty of time to ask questions.
