Because during sleep, your body functions differently than when you are awake. These sensors are the only way to determine just how well your body is functioning while you are asleep. This is the only way to get a complete picture of what is happening.
You will be asked to report to the admitting office to complete the necessary paperwork on the evening of your PSG. The technician will meet you in the lobby and escort you to the sleep center. You will then be requested to change into your bedclothes. The technician will then begin applying the electrodes and other sensors to your head and other parts of your body.
After all the electrodes have been attached, you may watch TV, etc., until the technician is ready to start the test. Immediately before the lights are out, additional sensors for monitoring respirations, etc. may be attached, depending on the type of the study.
No, you will not be given any medications. However, if you normally take medications prescribed by your physician during the hours you will be in Sleep Center, please bring them with you and take them as usual, unless directed otherwise.
A trained polysomnographic technician will remain in the control room of the sleep center monitoring you continuously through the night. Often there will be another person who is also having sleep testing in the next bedroom. The technician will make every attempt to make sure your stay in the sleep center is pleasant as possible.
After you wake up and inform the technician that you want to get out of bed, the technician will detach all electrodes and other sensors. You will be asked to complete a short questionnaire. After this, you will be ready to leave if you are not scheduled for daytime testing.
After the PSG, the polysomnographic technologist and board-certified sleep disorder specialist would review the information and determine what stages of sleep you went into and look for any respiratory events, leg movements, etc. A sleep disorder specialist then prepares a complete report. After the specialist has completed interpreting the study, the report will be sent to your physician with a treatment plan proposed within a week. If needed, you may have a follow-up visit to the sleep center.
