What is the normal range for Central Venous Pressure (CVP)?

The normal range for Central Venous Pressure (CVP) is typically between 2 to 8 mmHg, although the commonly referenced values often indicate 0 to 6 mmHg to account for various clinical interpretations and contexts. This measurement provides essential information about the patient’s fluid status and right heart function. It reflects the pressure in the thoracic vena cava near the right atrium and can indicate the venous return to the heart.

In a clinical setting, a CVP within this normal range suggests adequate venous return and right ventricular filling pressure. Values outside this range can help indicate conditions such as hypovolemia, heart failure, or fluid overload, guiding therapeutic interventions.

The other ranges provided in the question do not accurately reflect the generally accepted values for CVP, emphasizing why the chosen answer provides the most reliable and clinically relevant information.
