What is considered a normal central venous pressure (CVP) reading?

Central venous pressure (CVP) is a measure of the pressure in the thoracic vena cava, reflecting the volume status and function of the right side of the heart. A normal CVP reading typically falls within the range of 0 to 10 cm H2O. This range indicates that the heart is effectively managing the return flow of blood and that venous return is adequate without excessive pressure, which could indicate heart failure or fluid overload.

A CVP reading below 0 cm H2O is generally not seen in healthy patients and can indicate significant hypovolemia or inadequate venous return, while readings above 10 cm H2O may suggest issues such as fluid overload, cardiac dysfunction, or increased intrathoracic pressure. The range for normal CVP is therefore crucial for assessing a patient’s hemodynamic status, guiding fluid resuscitation, and monitoring cardiovascular function.
