Learning issue: Jugular vein A, C, V components Name: MH I apologize for the delay, but with Pete’s advice I had a better idea what I was looking for. Jugular venous pulse and pressure The jugular veins, which empty directly into the superior vena cava, reflect the activity of the right side of the heart and offers clues to its competency. The level at which the jugular venous pulse is visible gives an indication of right arterial pressure The activity of the right side of the heart is transmitted back through the jugular vein as a pulse that has five identifiable components-three peaks and two descending slopes. A wave- The a wave, the first and most prominent component, is the result of a brief backflow of blood to the vena cava during the right atrial contraction

Unformatted text preview: • C wave- The c wave is a transmitted impulse from the vigorous backward push produced by closure of the tricuspid valve during ventricular stroke • V wave- The v wave is caused by increasing volume of concomitant increasing pressure in the right atrium. It occurs after the c wave, late in ventricular systole. • X slope- The downward x slope is caused by passive atrial filling • Y slope- The y slope following the v wave reflects the open tricuspid valve and the rapid filling of the ventricle.
