Polysomnography
Polysomnography is a comprehensive sleep study that involves monitoring biophysiological changes during sleep including brain waves, eye movements, muscle activity, heart rate, respiration, and oxygen levels. It is used to diagnose various sleep disorders like sleep apnea, insomnia, narcolepsy, and parasomnias. A polysomnography study involves setting up various sensors on the patient's head and body according to international standards and analyzing the recorded data to identify sleep stages and respiratory events during sleep. Polysomnography is considered the gold standard for diagnosing sleep disordered breathing like obstructive sleep apnea.
