What is Valsalva maneuver?
The Valsalva maneuver is a breathing method that may slow your heart when it’s beating too fast. To do it, you breathe out strongly through your mouth while holding your nose tightly closed. This creates a forceful strain that can trigger your heart to react and go back into normal rhythm.
How do you perform Valsalva maneuver for SVT?
A modified Valsalva maneuver involves a strain of 40 mm Hg pressure for 15 seconds with the patient in the semirecumbent position, followed by supine repositioning with 15 seconds of passive leg raise at a 45-degree angle.

Is the Valsalva maneuver bad?
Many trainers, fitness “gurus,” and medical professionals argue that the Valsalva maneuver is dangerous because of its ability to rapidly spike blood pressure. It’s true that the Valsalva maneuver can raise blood pressure three to four times above resting levels, but there’s little evidence this is bad for you.
What happens to blood pressure during Valsalva maneuver?
The increase in intrathoracic pressure that occurs during the Valsalva maneuver incites a sequence of rapid changes in preload and afterload stress. During the strain, venous return to the heart is decreased and peripheral venous pressures become increased.
Who should avoid Valsalva maneuver?
Can Valsalva damage ears?
Forcing air against these soft tissues just locks them shut. No air gets to the middle ears, which do not equalize, so barotrauma results. Even worse, blowing too hard during a Valsalva maneuver can rupture the round and oval windows of the inner ear.

How is Valsalva maneuver used to treat SVT?
Breathing out increases the pressure inside the aorta, stimulating the parasympathetic nervous system and decreasing the heart rate again. The Valsalva maneuver helps treat a rapid heart rate. Doctors can use the Valsalva maneuver to treat people with supraventricular tachycardia (SVT).
Is it dangerous to do the Valsalva maneuver?
A heart rate of this speed can be dangerous because the heart cannot pump enough blood when it beats so quickly. SVT often requires emergency treatment. Once emergency responders have identified a person’s heart rhythm and determined that their blood pressure is stable, they may demonstrate how to perform the Valsalva maneuver.
