Talk:Jugular venous pressure

According to most textbooks, the patient should be positioned at 45 degrees (not 30), although in my view, it is more important that the patient is in a position where the JVP is visible. Axl 14:36, 7 Dec 2004 (UTC)

Depends if you want to measure the pressure, or observe the waveform.

Positive trial
http://archinte.ama-assn.org/cgi/content/full/166/19/2132 - more positive about examination, needs inclusion. JFW | T@lk  12:18, 6 May 2008 (UTC)


 * But this trial looked at the external jugular vein, which correllated well with the CVP. No waveforms for you, though. JFW | T@lk  12:19, 6 May 2008 (UTC)

The title of the article is confusing. Three terms are commonly used with regard to the state of the cardiovascular system as determined by observing jugular veins. Those three terms are jugular venous distension (JVD), jugular venous pressure (JVP) and jugular venous pulsation (also abbreviated JVP) The article as written mostly deals with jugular venous pulsation which is the interpretation of wave forms of the right internal jugular vein which is used because it is the most direct path to the right atrium where the pulsations largely originate.

Jugular venous pressure and jugular venous distention are the same thing: measurement of the pressure above the phlebostatic axis which passes through the center of the right atrium. In adult humans, the distance from the sternomanubrial angle (SMA)to the axis is about 5 cm. To measure jugular venous pressure, the patient is reclined till the the pulsations are visible above the clavicle. The "zero" end of a centimeter ruler is placed vertically on the SMA. A straight edge is then run horizontally from the top of the visible pulsations to the ruler. If the intersection is at, for example, 2 cm, this distance would be added to the 5 cm for a reported as a jugular venous pressure of 7 cm.

The picture in the article is of the right external jugular vein which has a more circuitous route to the right atrium. — Preceding unsigned comment added by 96.33.11.35 (talk) 10:14, 3 February 2014 (UTC)

Image of JVP
I have an issue with the image thats used here. It is the external jugular, which is not what you use to examine the JVP. This is actually a trick question that examiners use on medical students. So definitely, shouldn't confuse people any more! When I find a better picture, I'll replace it unless someone has any major concerns! 140.203.217.6 (talk) 07:24, 6 May 2015 (UTC)

Origin of the terms a, c, v, x, and y?
Anyone able to shed any light on this?

I've found that James Mackenzie (cardiologist)'s book in 1902 talks about the central waveform, but I cannot tell if this is the original use?

I cannot find anything on the origin of the x' (x prime) term

Is there a source for the origin of this term? DemandAmbition (talk) 14:00, 9 July 2017 (UTC)
