The Valsalva maneuver may help check for a dural tear following certain spinal operations, such as a microdiscectomy. An increase in intra-spinal pressure will cause cerebral spinal fluid (CSF) to leak out of the dura, causing a headache. [citation needed] The Valsalva maneuver has been associated with transient global amnesia. [17] [18] [19 ...
The Trendelenburg position along with the Valsalva maneuver, termed as modified-Valsalva maneuver, can also be used for the cardioversion of supraventricular tachycardia. [ 5 ] The Trendelenburg position is helpful in surgical reduction of an abdominal hernia.
The sapheno-femoral junction is tested by the Valsalva maneuver, with the use of color Doppler being helpful at this stage. [35] The wall thickness of the vein [which?] is significantly increased in venous reflux, being approximately 0.58 mm in venous reflux, compared to up to 0.45 mm normally. [36]
Valsalva maneuver. Diagnosis of dysautonomia depends on the overall function of three autonomic functions—cardiovagal, adrenergic, and sudomotor. A diagnosis should at a minimum include measurements of blood pressure and heart rate while lying flat and after at least three minutes of standing.
For AVNRT, sometimes people can use vagal maneuvers as well, which are ways to activate the vagus nerve, which tends to block the AV node temporarily, therefore potentially stopping the episode. Some methods include a carotid sinus massage, as well as a valsalva maneuver—which is forced exhalation against a closed airway.
The Valsalva maneuver can also help to temporarily unblock or equalize the pressure in the middle ear. To do this, simply pinch your nostrils closed with one hand and blow air through your nose ...
The Valsalva maneuver should be the first vagal maneuver tried [13] and works by increasing intra-thoracic pressure and affecting baroreceptors (pressure sensors) within the arch of the aorta. It is carried out by asking the patient to hold his/her breath while trying to exhale forcibly as if straining during a bowel movement.
