Sleep studies, or polysomnograms, are tests used to diagnosis sleep disorders. Typically, these studies are conducted in a sleep center or sleep lab after being referred by your primary care physician.

Prior to your sleep study, it is best to limit caffeine, alcohol, and daytime naps to avoid interference with your sleep study. It is important to discuss any medication with your sleep specialists as well as any other concerns you may have regarding the sleep study. Items you will need to bring with you to your appointment: your photo id, insurance card, completed registration packet (mailed to you after scheduling) and something comfortable to sleep in.

The room in which the sleep study is done will be a pleasant environment similar to your own bedroom at home. There will be a dresser for personal belongings, a television, and the testing equipment needed to complete the study. You will also have access to a full bathroom with a walk in shower stall.

During the sleep study, electrodes will be placed on your scalp, face, chest, limbs, and finger in the form of a sticky patch. The electrodes will record your brain activity, eye movements, heart rate, blood pressure, and blood oxygen levels while you sleep.

Your chest movements will also be measured to record the strength and duration of inhaled and exhaled breaths. These movements are measured by elastic belts placed around the chest and abdomen.

All sensors and data recording devices are connected to a computer in another room where data is collected and analyzed.

If it is determined that you have sleep apnea, another sleep study may be required. The follow up sleep study is called a therapeutic sleep study. The Therapeutic sleep study is a repeat of the first night of testing where the technician will introduce the CPAP therapy. This allows the sleep specialist to find the appropriate setting for the CPAP equipment that will be used to reduce or eliminate your Apneas.

CPAPs are the most common treatment for sleep apnea. A CPAP keeps your airway open during sleep through the use of mild positive
air pressure.
