Description

Valsalva Maneuver is a respiratory sample consisting of making a forced exhalation with closed glottis. This test is performed to assess the adaptability of the cardiovascular system during exercise, usually causes bradycardia and heart volume changes.

The patient blows his nose under the nostrils are plucked. It is recommended to perform in two conditions: to observe the possible communication with the maxillary sinus after an extraction or to highlight the line AH.

Valsalva maneuver helps to detect mouth communication with the maxillary sinus. Thus, if a communication during the Valsalva maneuver is thoroughly aerated blood into the socket. Otherwise do not notice changes in the socket. After extraction, some authors contraindicate Valsalva maneuver, because this maneuver could increase mucosal breach.

The Valsalva maneuver is used with patients who have suspected heart abnormalities, often in conjunction with echocardiography. The maneuver is based on the fact that when a patient forcibly exhales against a closed nose and mouth while bearing down, as if having a bowel movement, specific changes occur in blood pressure and the rate and volume of blood returning to the heart. Comparing the changes in a diseased heart to those expected in a normal heart gives clues to the type and location of heart damage. ...
