Valsalva maneuver

Valsalva maneuver
A maneuver in which a person tries to exhale forcibly with a closed glottis (the windpipe) so that no air exits through the mouth or nose as, for example, in strenuous coughing, straining during a bowel movement, or lifting a heavy weight. The Valsalva maneuver impedes the return of venous blood to the heart. Named for Antonio Maria Valsalva, an Italian anatomist (1666-1723).
