Valsalva maneuver

（重定向自Valsalva manoeuvre）

Blood pressure (systolic) and pulse rate during a normal response to Valsalva’s maneuver. Forty millimeter mercury pressure is applied at 5 seconds and relieved at 20 seconds.

The Valsalva maneuver or Valsalva manoeuvre is performed by moderately forceful attempted exhalation against a closed airway, usually done by closing one's mouth, pinching one's nose shut while pressing out as if blowing up a balloon. Variations of the maneuver can be used either in medical examination as a test of cardiac function and autonomic nervous control of the heart, or to "clear" the ears and sinuses (that is, to equalize pressure between them) when ambient pressure changes, as in diving, hyperbaric oxygen therapy, or air travel.
