	Valsalva Maneuver \| AHealthyMe.com
		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.
		The Valsalva maneuver should not be performed on patients who have severe coronary artery disease, have experienced recent heart attack, or where there is a moderate to severe reduction in blood volume.

	Valsalva maneuver
		Valsalva's initial intention for the maneuver was as a method of expressing pus from the middle ear.
		A Valsalva maneuver performed against a closed glottis results in a drastic increase in pressure in the thoracic cavity, the airtight section of the torso that houses the lungs and heart.
		The Valsalva maneuver is used as a pressure equalization technique by scuba divers and airplane passengers to avoid barotrauma and discomfort inside their ears when they move to a higher pressure breathing environment.

	Valsalva maneuver - Information from Reference.com
		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.
		The Valsalva maneuver may be used to arrest episodes of supraventricular tachycardia.

	Stuttering and the Valsalva Mechanism: Introduction
		The Valsalva mechanism is a neurologically coordinated team of muscles throughout the body which act together in the performance of a Valsalva maneuver.
		The Valsalva hypothesis might therefore explain why stuttering is often reduced when the speaker uses a "gentle onset" of voice and "light contacts" in articulation, or starts speech with a stream of "passive airflow." Such methods would tend to avoid abrupt increases in air pressure, and thereby reduce the likelihood of a Valsalva maneuver.
		Valsalva tuning may also lead to excessively forceful closures of the mouth or larynx during articulation, resulting in the blocking of speech.

	The Valsalva Maneuver - Why So Many People Are Forced To Do It Everyday
		In a Valsalva Maneuver, attempting to exhale with the mouth and nose closed increases the pressure in the thoracic cavity because the air cannot escape.
		During a Valsalva Maneuver, with the holding of the breath and straining, the diaphragm is forced downwards by the increased pressure inside the thoracic cavity.
		The Valsalva Maneuver adversely affecting the cardio-vascular system is the causative factor of defecation syncope (fainting) and death.

	Valsalva Stuttering Network - Introduction
		It is designed to perform a Valsalva maneuver to increase air pressure in the lungs by forcefully closing the upper airway while the chest and abdominal muscles contract.
		The forceful closures associated with a Valsalva maneuver need not be limited to the usual effort closure of the larynx, but may instead involve tight closure of the lips or tongue, depending on which structure initiates blockage of the airway.
		Valsalva Control is holistic in nature, including a variety of exercises as well as changes in attitudes toward speech and stuttering.

		The systematic arterial pulse pressure response is the clinical paradigm of the Valsalva maneuver.
		The aim of this study was to evaluate hemodynamically the relationship between the patter of response to the Valsalva maneuver of aortic pulse pressure and the degree of cardiac dysfunction.
		In addition, since all four indices used to characterize the Valsalva maneuver identified only a single aspect of the hemodynamic pattern of response, multiple regression analsis was performed to assess whether these indices together were able to better predict any of the resting hemodynamic parameters.

	Valsalva maneuver - Definition, explanation
		A Valsalva maneuver is any attempted exhalation against a closed glottis or against a closed mouth and nose.
		The Valsalva maneuver is used as a pressure equalisation technique by scuba divers and airplane passengers to avoid barotrauma and discomfort inside their ears when they move to a higher pressure breathing environment.
		Some cardiologists measure the Valsalva ratio, which is the maximum heart rate in phase II over the minimum heart rate in phase IV of the Valsalva Maneuver.

	Valsalva-Stuttering Research Proposal
		The ordinary Valsalva maneuver involves tight closure of the vocal and vestibular folds of the larynx (called effort closure) for the purpose of sealing off the respiratory tract, accompanied by contraction of the parietal muscles of the abdomen and thorax.
		However, the forceful closures associated with a Valsalva maneuver need not be limited to the usual effort closure of the larynx, but may instead involve tight closure of the lips or tongue, depending on which structure initiates blockage of the airway.
		By understanding the Valsalva mechanism and learning to control it through various exercises (which I refer to as "Valsalva Control"), I had overcome a severe stuttering problem to such an extent that I was able to function effectively as a trial lawyer.

	CARE EF1 Protocol (Site not responding. Last check: )
		The Valsalva maneuver is defined as expiration against a closed glottis that increases the intrathoracic pressure by at least 30-40 mm Hg and lasts for at least 10 seconds.
		The Valsalva maneuver has been used in clinical situations since 1704 when it was described by Valsalva as a technique for expelling pus from the middle ear by expiration against a closed nose and mouth.
		Currently, the Valsalva maneuver is taught as an adjunct to listening to murmurs and as a therapeutic tool for converting arrhythmias.

	New Circulatory Findingsin the Valsalva maneuver
		We conclude that the blood pressure decrease during the Valsalva maneuver is related to a variable decrease in thoracic blood volume which may be sufficient to preclude pressure recovery during phase II even with normal resting peripheral vasoconstriction.
		The Valsalva maneuver depends on vascular as well as autonomic activation, which broadens its utility but complicates its analysis.
		Thus, thoracic hypovolemia during the Valsalva maneuver is closely related to splanchnic hyperemia and weakly related to regional changes in blood volume elsewhere.

		The Valsalva's maneuver was named after the Italian anatomist Antonio Maria Valsalva, who defined the Valsalva ligaments and anatomy related to the forcible exhalation effort against a closed glottis.
		Valsalva retinopathy occurs secondary to increased intra-thoracic or intra-abdominal pressure that is transmitted or transferred to the eye and its systems.

	Echocardiography
		Since both abnormal blood pressure response to the Valsalva maneuver and a "pseudonormalized" Doppler transmitral E/A ratio probably represent elevated left ventricular filling pressure, we postulated that there would be a positive correlation between the two in a group of patients with dilated cardiomyopathy and abnormal systolic function.
		Hemodynamic responses to the Valsalva maneuver were studied in eight healthy subjects (group 1) and eight patients with ASD (group 2) using Doppler echocardiography.
		The Valsalva maneuver was evaluated by echocardiography in three groups: A) 10 normal volunteers, B) 10 patients with no history of heart failure and normal ejection fractions, and C) 10 patients with heart failure and depressed ejection fractions.

		You were probably taught that the Valsalva maneuver is a technique to equalize, or "pop" your ears.
		The technique originally described by Valsalva was to forcibly exhale against a closed glottis, by closing the vocal cord together, as in a cough.
		Either technique may increase pressure in the chest cavity, impeding venous return of blood to the heart, and because of that, is often used to study cardiovascular effects of decreased cardiac filling and output.

	Achalasia, The Valsalva Maneuver, and Sudden Death: A Case Report
		The death was ascribed to a cardiac arrhythmia arising from the Valsalva maneuver, which she used to move her ingested food across the stenotic gastroesophageal juncture.
		The Valsalva maneuver, which increases the intrathoracic pressure by forcing expiratory effort against a closed glottis, has been associated with cardiac arrhythmias and rarely, sudden death.
		Lethal cardiac arrhythmias should be considered when sudden deaths occur in individuals with esophageal motility disorders, as well as in other situations where the Valsalva maneuver may have been used, and where no other anatomic cause of death is identified.
