The jugular veins: gateway to the heart

I read with interest the Medical Education article by Elder and Nair1 and I was surprised that it suggested that the assessment of the jugular vein pulsation should be done “in whatever position the patient is in”. I am often shocked by the fact that medical students are taught to look for the jugular venous pulsation with the patient positioned at 45 degrees.

In a person who is asymptomatic and lying flat, without any obvious distress and who has no fluid retention clinically, the pressures in the right atrium will be in the range of 2–8 mmHg and it would be impossible to see the top of the jugular venous pulsation if the patient was elevated.

In most patients, the jugular venous pulsation should be assessed by examining the patient in the supine position. Elevation should only be undertaken if there is obvious fluid retention or dyspnoea when lying flat. If there is any question after examining the patient in the supine position, then the patient may be elevated to ensure that the correct peak of the jugular venous pulsation is seen. However, if students are taught to examine the jugular venous pulsation only when the patient is sitting up, then it will seldom be seen in a person who has normal right atrial pressure.

I believe this concern should be brought to the attention of all clinical educators so that they clearly explain when the jugular venous pulsation should be examined in the supine position and when it is necessary to elevate the patient to the 45 degrees position.
