What does polysomnography primarily assess in a patient?

Polysomnography primarily assesses breathing patterns and sleep stages in a patient. This comprehensive test records various physiological parameters while a patient sleeps, including respiratory airflow, effort, and oxygen saturation levels. It evaluates how these factors change throughout different stages of sleep, such as REM (rapid eye movement) and non-REM sleep. By capturing such data, polysomnography is instrumental in diagnosing sleep disorders like obstructive sleep apnea, central sleep apnea, or other sleep-related breathing issues.

The focus on both breathing and sleep architecture allows healthcare professionals to identify disruptions in the sleep cycle that can impact overall health and well-being. This makes polysomnography a crucial tool in sleep medicine for understanding the complexities of sleep behavior and related disorders.
