some facts of JVP

JVP.

Which vein : Internal Jugular vein .
why internal,why not external : Because internal JV (not external) lies in close continuity with Superior Vena cava and Right atrium.

Concept : Height of Internal Jugular Venous pulsation reflects the pressure of right atrium of Heart. So its a way to measure the pressure of RA and can be correlated with some abnormalities that changes pressure in RA (Jugular venous pulsation)


some facts of JVP.
1. JVP is not seen easily, by applying a gentle pressure on abdomen (Hepato Jugular Reflex) JVP can be highlighted.

2. JVP is elevated in Volume overload in Right Heart ,so in Right Heart Failure, JVP is reduced in Hypovolaemia.

3. TRicuspid regurgitation produces giant V waves that coincide with ventricular systole.
