What is the normal central venous pressure (CVP) range in mmHg?

Central venous pressure reflects right atrial preload and is measured via a central venous line. The normal range is about 2 to 6 mmHg. Values below this (around 0–2) suggest low preload or hypovolemia. Values above the range (6–10 or higher) indicate elevated right-sided pressures from fluid overload, right heart dysfunction, or increased intrathoracic pressure. Among the options, 2–6 mmHg best represents the normal CVP.
