jugular venous pressure (JVP)

blood pressure in the jugular vein, which reflects the volume and pressure of venous blood. JVP is estimated by positioning the head of a supine patient at a 30- to 45-degree angle and observing the neck veins. If the neck veins are filled only to a point a few millimeters above the clavicle at the end of exhalation, JVP is usually normal. With an elevated JVP the neck veins may be distended as high as the angle of the jaw. An elevated JVP is typically a sign of congestive heart failure.

jugular venous pressure

Abbreviation: JVP
Back pressure exerted into the jugular veins from the right side of the heart.

Patient care

To estimate jugular venous pressure, have the patient lie on his or her back with the chest, neck, and head elevated 30 degrees above the horizontal. Measure the vertical height of the fullness seen as the jugular vein fills. In the healthy (and in the dehydrated) little or no blood is seen in the jugular veins, and they appear to be flat. In right-sided heart failure, the column of blood distends the jugular veins to a height of 5 to 6 cm or more.

On examination, he had a pulse of 96 beats/minute regular, blood pressure of 115/75 mmHg, raised jugular venous pressure (JVP), and pitting pedal oedema.
In advanced stages, there may be signs of valvular regurgitation and right heart failure which include elevated jugular venous pressure with accentuated V waves (in the presence of tricuspid regurgitation), diastolic murmur of pulmonary regurgitation, holosystolic murmur of tricuspid regurgitation, right ventricular S3 gallop, pulsatile hepatomegaly, peripheral edema and ascites.

1] These guidelines noted that the presence of elevated jugular venous pressure, a third heart sound, and laterally displaced apical impulse are "virtually diagnostic in patients with compatible symptoms," while the sensitivity and specificity of other clinical features have not proven sufficient to establish the diagnosis.
