What does PSG stand for in the context of sleep studies?

In the context of sleep studies, PSG stands for Polysomnography. This is a comprehensive recording of the biophysics of sleep. A polysomnography evaluates various physiological parameters during sleep, including brain waves, oxygen levels in the blood, heart rate, breathing, and eye and leg movements. This diagnostic tool is essential for identifying sleep disorders such as sleep apnea, insomnia, and various parasomnias.

Polysomnography combines inputs from multiple sensors to provide a complete picture of a person's sleep patterns and disturbances. The results from a PSG can inform treatment options and help healthcare providers develop appropriate interventions for sleep disorders. Understanding how polysomnography works is crucial for those studying respiratory care, as many sleep-related issues have significant implications for respiratory function and overall health.
