Medical definitions for Valsalva maneuver

Valsalva maneuver

[ văl-săl′və ]

n.

Expiratory effort against a closed glottis, which increases pressure within the thoracic cavity and thereby impedes venous return of blood to the heart. The maneuver results in changes in blood pressure and heart rate and is used in conjunction with other tests to diagnose cardiac abnormalities and to treat various conditions, especially some abnormal heart rhythms.

Expiratory effort when the mouth is closed and the nostrils are pinched shut, which forces air into the eustachian tubes and increases pressure on the inside of the eardrum.
