Polysomnography (PSG) is a sleep study that records your brain waves, heart rate, and breathing while you sleep. It helps doctors understand sleep disorders and improve your sleep quality.
If you're having trouble sleeping, your doctor might recommend a polysomnography test to diagnose any underlying issues.
PSG, or polysomnography, is a comprehensive sleep study used to diagnose sleep disorders by monitoring brain waves, oxygen levels, heart rate, and breathing during sleep.
PSG testing involves recording various physiological parameters during sleep, including EEG, EOG, EMG, and respiratory patterns, to assess sleep quality and identify any abnormalities.
Normal sleep efficiency, measured during a PSG, is typically considered to be 85% or higher, indicating that a person spends most of their time in bed actually sleeping.
A polysomnography test is conducted in a sleep lab where sensors are attached to the patient’s body to monitor sleep stages, breathing, and other functions throughout the night.
