Val•sal′va maneu`vervælˈsæl və(n.)
an attempt to expel air against a closed glottis or closed lips and nostrils, used for adjusting pressure in the middle ear.
Origin of Valsalva maneuver:
after Antonio M. Valsalva (1666–1723), Italian anatomist who devised it
The Valsalva maneuver or Valsalva manoeuvre is performed by moderately forceful attempted exhalation against a closed airway, usually done by closing one's mouth, pinching one's nose shut while pressing out as if blowing up a balloon. Variations of the maneuver can be used either in medical examination as a test of cardiac function and autonomic nervous control of the heart, or to "clear" the ears and sinuses when ambient pressure changes, as in diving, hyperbaric oxygen therapy, or aviation. The technique is named after Antonio Maria Valsalva, a 17th-century physician and anatomist from Bologna whose principal scientific interest was the human ear. He described the Eustachian tube and the maneuver to test its patency. He also described the use of this maneuver to expel pus from the middle ear. A modified version is done by expiring against a closed glottis. This will elicit the cardiovascular responses described below but will not force air into the Eustachian tubes.
U.S. National Library of Medicine
Forced expiratory effort against a closed GLOTTIS.
