The Jugular Venous Pressure

"Lookout for the raised JVP to help you in diagnosing conditions such as the CHF"

My professors and lecturers would tell me that.

But honestly, I never did appreciate the "raised JVP" well enough, ever. Many times, I will just pretend that I am able to see the JVP, and I would say whether it is raised or not in relation to the patient's history and other physical signs.

I wonder if there'd be a huge variation, in what I perceive as the JVP, and what my colleagues perceive as the JVP, and what senior doctors would perceive as the JVP.

Would I ever trust my estimation of the JVP to make a life-changing decision on patient management? 

I doubt so.
