Exempel på hur man kan använda VALSALVA i en mening

• Active opening of the Eustachian tube (through actions like swallowing or the Valsalva maneuver) is required to equalize the pressure between the middle ear and the ambient atmosphere as the plane descends.
• The Valsalva maneuver is performed by a forceful attempt of exhalation against a closed airway, usually done by closing one's mouth and pinching one's nose shut while expelling air, as if blowing up a balloon.
• He acted as prosector to Antonio Maria Valsalva (one of the distinguished pupils of Malpighi), who held the office of demonstrator anatomicus in the Bologna school, and whom he assisted more particularly in preparing his celebrated work on the Anatomy and Diseases of the Ear, published in 1704.
• Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body.
• An aortic sinus, also known as a sinus of Valsalva, is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve.
• Due to the risk of serious side effects, the FDA states that sotalol should generally be reserved for people whose ventricular arrhythmias are life-threatening, or whose fibrillation/flutter cannot be resolved using the Valsalva maneuver or another simple method.
• He coined the term Eustachian tube and he described the aortic sinuses of Valsalva in his writings, published posthumously in 1740.
• In the same year his anatomical dissertation De aquaeductibus auris humane internae, following the work of Guichard Joseph Duverney and Antonio Maria Valsalva and anticipating that of Hermann von Helmholtz, described the vestibule, semicircular canals, and cochlea of the osseus labyrinth of the internal ear, demonstrated the existence of the labyrinthine fluid, and formulated a theory of resonance and hearing.
• Vascularity is enhanced by extremely low body fat (usually below 10%) and low retained water, as well as the muscle engorgement ("pump") and venous distension accentuated by the vigorous flexing and potentially hazardous Valsalva effect which characterize competitive posing.
• The Valsalva maneuver should be the first vagal maneuver tried and works by increasing intra-thoracic pressure and affecting baroreceptors (pressure sensors) within the arch of the aorta.
• It has been shown that performing a Valsalva maneuver (involving "bearing down" and increasing breath pressure against a closed glottis, which occurs frequently during exertion) may be related to retrograde flow of blood in the jugular vein, and therefore, presumably, cerebral blood circulation, in patients with TGA.
• The ultrasound probe should move from lateral to medially, a hypoechoic mass should appear anteriorly and medially to the inferior epigastric artery during Valsalva maneuver.
• The tragicus, also called the tragus muscle or Valsalva muscle, is an intrinsic muscle of the outer ear.
• Because it is a more regulated procedure that does not employ the diaphragm, the Frenzel equalisation technique is clearly more appealing to freedivers than the Valsalva technique, especially for freedivers who frequently need to descend at speed.
• Vagal maneuvers (most commonly the Valsalva maneuver) can be used to distinguish between ventricular tachycardia and supraventricular tachycardia by slowing the rate of conduction at the SA or AV nodes.
• Some examples of the work of the MicroG include; lower body negative pressure (LBNP) box; lower body positive pressure (LBPP) box; Bárány chair; body suspension device for microgravity and hypogravity simulations; tilt-table for microgravity simulation; small centrifuge to study the effects of hypergravity on plants; small hypobaric chamber; portable dark chambers; pressure measurement system for use during the Valsalva Manoeuvre and the Earlobe Arterial Blood Collector (EABC).
• A cystometrogram will evaluate detrusor over-activity, bladder compliance, bladder capacity, and abdominal (Valsalva) leak pressure.
• Excessively strenuous efforts to equalise the ears using the Valsalva manoeuvre can overpressurise the middle ear, and can cause middle ear barotrauma.
