The CPSGT (Certified Polysomnographic Sleep Technician) is an essential role in the field of sleep medicine, responsible for conducting sleep studies to diagnose and treat various sleep disorders. Under the supervision of a registered polysomnographic technologist or sleep physician, CPSGTs perform tasks such as setting up equipment, monitoring patients during sleep studies, and recording critical data like brain waves, heart rate, and oxygen levels. Earning CPSGT certification through the Board of Registered Polysomnographic Technologists demonstrates proficiency in basic sleep study techniques.
