WebCentral venous pressure (CVP) is used almost universally to guide fluid therapy in hospitalized patients. Both historical and recent data suggest that this approach may be flawed. ... The basis for using CVP to guide fluid management comes from the dogma that CVP reflects intravascular volume; specifically, it is widely believed that patients ... Web1 Jugular Venous Distension. Jugular venous pressure (JVP), which reflects right atrial pressure (central venous pressure), is estimated by examining the internal jugular veins. We do not recommend using the external jugular vein pulsations to estimate central venous pressure, because valves in these veins may lead to inaccurate readings.
