What is the expected CVP range in a healthy adult?

The expected central venous pressure (CVP) range in a healthy adult is typically between 2-6 mmHg. This measurement reflects the pressure in the thoracic vena cava, near the right atrium of the heart, and is a useful indicator of a patient’s fluid status and cardiac function.

Within this range, CVP values provide insight into the volume of blood returning to the heart and the heart's ability to pump that blood effectively. A CVP below 2 mmHg may suggest hypovolemia (low blood volume), while values above 6 mmHg can indicate conditions such as heart failure or fluid overload.

In practice, the selected range of 2-6 mmHg is most commonly accepted and widely used in clinical settings, making it a key reference point for healthcare providers managing patients in critical or acute care settings. Understanding this range allows for better assessment and early detection of potential hemodynamic issues.
