The valsalva maneuver is an attempt to forcibly exhale with the nose and mouth closed.
Trapping air inside the lungs in order to provide air pressure, against which you push for excretion and childbirth, or stabilization for lifting. This is also called "thoracic fixation". Term found in About the Voice: Anatomy 201.
term used to describe a condition created by the patient when they block exhalation and increase pressure in the chest cavity by contracting the muscles of the stomach and chest. Typically, many people perform a valsalva maneuver when they have a bowel movement.
The action of closing the airways and straining down on the abdominal muscles (such as when straining to have a bowel movement).
To force the breath against a closed throat, i.e., holding the breath, tightening the muscles, and making a strong effort to lift a weight; The valsalva maneuver is especially dangerous to clients with high blood pressure or heart disease.
The maneuver involves forcefully exhaling while all of your air passageways are closed. This maneuver may be used when straining with bowel movements.
An attempt to focibly exhale with the glottis, nose and mouth closed. Causes increased intrathoracic pressure, slowing of the pulse, decreased return of blood to the heart, and venous pressures-childbirth, difficult bowel movement, isometric contraction
In medicine, the Valsalva maneuver is performed by forcibly exhaling against closed lips and pinched nose, forcing air into the middle ear if the Eustachian tube is open. This maneuver with slight modifications can be used as a test of cardiac function and autonomic nervous control of the heart or to ‘clear’ the ears (equalize pressure) when ambient pressure changes, as in diving or aviation.
