THE SLEEP STUDY: The sleep study or polysomnogram, is a combination of several diagnostics tests all recorded simultaneously during sleep. Brain wave activity or EEG will be recorded by attaching electrodes with adhesive to the scalp. Eye movements and chin muscle will also be monitored in this manner. Depending on your physician’s request, other monitors may be applied to monitor breathing, airflow and oxygen level. The equipment may be minimally uncomfortable, but does not prevent sleep, nor interfere with a meaningful sleep study. Once the study has started, you have the right to discontinue the test for any reason, however please be aware that a shorter test may not be as reliable or as useful for the interpreting physician. The full charge for the study will be submitted for payment. Sleep Clinic of Washington patients cannot stay in the lab and sleep without properly being monitored. Therefore, please make sure that if you decide to discontinue your test during the middle of the night that you have proper arrangements for getting home, as you may not be allowed to drive yourself if you are sleep deprived.
