A polysomnogram sleep study will typically record a minimum of 11 channels requiring a minimum of 22 wire attachments to the patient. Electrodes are attached to the chin, the scalp and the outer edge of the eyelids. Monitors attached to the chest record the heart rate and breathing.
The results of the Polysomnography test are interpreted by the specialist doctor who writes a report which is sent to the referring physician. The results usually contain specific recommendations based on the test results. For example if Obstructive sleep apnea was evident then the use of a CPAP nasal breathing mask covering the nose and mouth might be recommended.
