Which of the following is a normal value of Central Venous Pressure (CVP)?

The normal value for Central Venous Pressure (CVP) generally ranges from 2 to 6 mmHg, with many references indicating an average of approximately 5 mmHg. A value of 4 mmHg falls within this normal range, indicating that the venous return to the heart and the right atrial pressure are both functioning properly.

Central Venous Pressure reflects the pressure of blood in the thoracic vena cava, near the right atrium, providing important insight into a patient’s fluid status and heart function. A CVP that measures below or above the normal range can indicate fluid overload or dehydration respectively.

Values such as 8 mmHg and 10 mmHg would suggest elevated right atrial pressure, typically associated with conditions like heart failure or volume overload, while a value of 6 mmHg, while within the upper limit, may still be indicative of some fluid accumulation but is still considered close to normal.

In summary, a CVP of 4 mmHg is an appropriate representation of a normal value, reflecting normal hemodynamics.
