jugular venous pressure

(redirected from Jugular vein distension)

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.
