The 10 mL syringe is useful in generating the recommended standard of 40 mmHg intrathoracic pressure for the Valsalva manoeuvre.

Abstract

OBJECTIVE The Valsalva manoeuvre (VM) continues to be first-line management for haemodynamically stable supraventricular tachycardia in the acute setting. 40 mmHg of intrathoracic pressure is seen as an essential component of the VM. Anecdotally, blowing into a 10 mL syringe to move the plunger is one method of pressure generation; however, to date its… (More)
