VALSALVA MANEUVER Meaning and
Definition
-
The Valsalva maneuver refers to a breathing technique that involves forceful exhalation against a closed airway. It is performed by closing the mouth and nose while attempting to exhale with increased pressure. This maneuver was named after Antonio Maria Valsalva, an Italian physician who first described it in the 18th century.
During the Valsalva maneuver, the glottis, located in the throat, closes to prevent the air from escaping. As a result, pressure builds up in the chest, causing compression in various organs, blood vessels, and bodily systems. This technique can be voluntary or involuntary, and its effects differ depending on the duration and intensity.
The most common use of the Valsalva maneuver is to clear the ears, especially during changing altitudes or when experiencing pressure changes. It helps equalize the pressure between the middle ear and the external environment, alleviating discomfort or pain.
Additionally, the Valsalva maneuver is used in medical procedures, such as during eye examinations or cardiac assessments. It helps manipulate blood flow and pressure within the body for diagnostic purposes or to facilitate certain medical interventions.
However, it is important to note that the Valsalva maneuver should be performed cautiously, as excessive force or prolonged duration may lead to adverse effects. These can include decreased blood flow to the brain, increased strain on the cardiovascular system, and potential damage to delicate structures within the body.
In summary, the Valsalva maneuver is a breathing technique involving forceful exhalation against a closed airway, named after the Italian physician Antonio Maria Valsalva. It is commonly used to clear the ears and has medical applications in various procedures.
