jugular venous pressureAbbreviation: JVP
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.
