A Certified Polysomnographic Technician (CPSGT) is an entry-level certification for professionals in the field of sleep technology. CPSGTs assist in conducting sleep studies by setting up and monitoring equipment, recording patient data, and ensuring the comfort and safety of patients during the tests. They work under the supervision of more experienced professionals, such as Registered Polysomnographic Technologists (RPSGTs), to help diagnose sleep disorders like sleep apnea and insomnia. The CPSGT certification, provided by the Board of Registered Polysomnographic Technologists (BRPT), serves as a stepping stone for those pursuing advanced certification and a career in sleep medicine.
