How do you perform the Valsalva Maneuver?

• A. Instruct person to pinch nose, close mouth, and blow air from a pinched nose
• B. Drink water
• C. Tilt head back and sniff
• D. Pinch ears and hum

Answer: (A)

The Valsalva maneuver is about increasing intrathoracic pressure by forcing air out through a closed airway. This rise in chest pressure can stimulate the vagus nerve, which helps slow the heart rate in certain fast rhythms, and it also helps equalize pressure in the middle ear by opening the Eustachian tube. The way to do it is to pinch the nose shut, keep the mouth closed, and try to blow air out as if you’re blowing through the pinched nose. That action creates the expiratory effort against a closed airway, producing the desired pressure effect. Other options don’t generate the same controlled intrathoracic pressure change. Drinking water doesn’t affect heart conduction or ear pressure. Tilting the head back and sniffing doesn’t create the expiratory effort needed. Pinching the ears and humming may pressurize the ears somewhat but is not the standard technique for achieving the vagal and pressure effects of the Valsalva maneuver.
