What does a polysomnographic (PSG) evaluation involve?

A polysomnographic (PSG) evaluation involves monitoring multiple body functions during sleep, making it a comprehensive assessment tool in sleep medicine. This evaluation typically measures brain waves, oxygen levels in the blood, heart rate, and breathing, as well as eye and leg movements. By analyzing this variety of data, clinicians can diagnose sleep disorders such as sleep apnea, insomnia, and narcolepsy.

This holistic approach allows for a better understanding of the complex nature of sleep and how different physiological parameters interact during the sleep cycle. The multifaceted data gathered in a PSG can help inform treatment options and improve patient outcomes. In summary, the strength of a PSG evaluation lies in its ability to provide a complete picture of an individual's sleep physiology.
