it is an estimate of the central vonous pressure... it can be measured by:
1. identify the sternal angle.
2. make a perpendecular line (w/ a ruler, w/ its 0 side to the chest) to the floor.
3.make a nother perpendecular line (w/anything straight) to the ruler...wich levels w/ the hight of the j.v. wave...
(it is measured by Cm.)
how to know the jugular venous wave level:
1. identify the two heads of the sternocledomastoid muscle attaching to the clavicel...then go upwards(the vein goes up to the ear lope)...the wave can be seen..not palpated, biphasic, changes w/ respiration & body position.. w/ a positive abdominojugular reflex(w/ these previous charachterestics..u can differentiate it from the carotid artery, which is qiut deffecult for a beginner med.student!!).....
if u have any further questions....just click on the picture box...

The blood pressure in the jugular vein. Measured by a sphyngometer.

The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system. It can be useful is the differentiation of different forms of heart and lung disease.
The interpretation of JVP findings can be challenging and is becoming a lost art, as much of the subtle information previously obtained by careful observation of the JVP can now be gained easily with echocardiography and/or EKG. "Cannon a-waves", which result when the atrium contracts with the tricuspid valve still closed, (due to an arrhythmia) is one such example.
An elevated JVP is the classic sign of venous hypertension (e.g. right-sided heart failure). The paradoxical increase of the JVP with inspiration (instead of the expected decrease) is referred to as the Kussmaul sign.

jugular venous pressure is the pressure in the jugular vein :D
the vein is located in your upper neck, right under the jaw. the pressure is measured to know whether the patient has heart failure or not, and how severe it is.
about how to measure it, i dont know.

I'm only aware that the jugular vein is in the neck and an ECG m/c is of use.

in fact JVP needs picture to be explained... put in sample way it consists of :
1) "a wave" which represent atrial systole .
2) "c wave" which represent cuspos pulg of vent. valves during isovolumetric conc.
3) "v wave" which represent venou return to right atrium .
** clinical importance of JVP :-
1) "a wave" absence represents atrial fibrillation .
2) large "a wave" represents valve stenosis .
3) cannon "c wave" represnts third degree heart block..
4) large "c wave" represnts valve incompliance

I guess the way to measure it is to insert a catheter to that vein and measure it directly. The way its done like CVP monitoring...
