Certified Polysomnographic Technician (CPSGT) Practice Exam

EEG stands for Electroencephalogram. This term refers to a test that measures the electrical activity of the brain through small, flat metal discs called electrodes that are attached to the scalp. During sleep studies, EEG is crucial as it helps to monitor and record the different stages of sleep. It provides insights into brain wave patterns, allowing healthcare professionals to evaluate sleep stages, diagnose sleep disorders, and assess the overall health of the brain. Understanding EEG is fundamental for polysomnographic technicians, as it forms the basis for analyzing sleep data and identifying abnormalities like sleep apnea or other sleep-related issues.
