The Valsalva maneuver test is a medical procedure used to evaluate the function of the autonomic nervous system, cardiovascular health, and to diagnose certain types of dysautonomia. It involves a person attempting to exhale forcefully with a closed airway, which influences heart rate and blood pressure. The test is often employed in clinical settings to assess baroreceptor reflexes and cardiac function.
