AbstractThe evaluation of the jugular venous pulse (JVP) remains one of the most important elements of the physical examination. Unfortunately, the examination remains difficult for most clinicians since traditional methodology is not commonly used or understood. Echocardiography has shown that the right atrial pressure can accurately be predicted as normal by observing a 50% inspiratory collapse of the inferior vena cava. We have adapted this finding to the clinical examination and experience has shown that if the jugular vein collapses during deep inspiration that both the right atrial pressure and the JVP are normal. We propose that this finding, which is easily detected in most patients, be incorporated as a standard observation in the assessment of the JVP. Thus, when evaluated in the supine position, distended neck veins that do not collapse indicate an abnormally elevated venous pressure, while visible veins that collapse during deep inspiration or with a vigorous sniff suggest a normal JVP, and those that are not (or barely) visible that collapse indicate a low JVP. This methodology is applicable to most clinical situations.
