Val·sal·va maneuver

 (văl-săl′və, väl-säl′vä)
1. 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.
2. Expiratory effort against a closed glottis, which increases pressure within the thoracic cavity, causing decreased venous return of blood to the heart and a transient drop in blood pressure.

[After Antonio Maria Valsalva (1666-1723), Italian anatomist.]

Val•sal′va maneu`ver

(vælˈsæl və)
an attempt to expel air against a closed glottis or closed lips and nostrils, used for adjusting pressure in the middle ear.
[after Antonio M. Valsalva (1666–1723), Italian anatomist who devised it]
