What does the acronym PSG stand for?

The acronym PSG stands for Polysomnography. This term refers to the comprehensive study of sleep that records various physiological parameters during sleep, such as brain waves (EEG), oxygen levels in the blood (pulse oximetry), heart rate (ECG), and muscle activity (EMG). Polysomnography is primarily used to diagnose sleep disorders and assess sleep quality, making it a fundamental concept in the field of sleep medicine.

By understanding that PSG represents Polysomnography, one can appreciate its significance in evaluating conditions like sleep apnea, insomnia, and other disorders related to sleep. This diagnostic tool is essential for sleep technologists and healthcare professionals in providing effective treatment and improving patients' sleep health.
