What is the normal central venous pressure (CVP) value?

Explanation:
Central venous pressure reflects the pressure in the right atrium and thus the preload of the right ventricle, essentially gauging how much blood is returning to the heart at rest. In a healthy adult at rest, this resting pressure sits in the low millimeter range, typically about 2 to 6 mmHg. This range is the standard reference used clinically, recognizing that tiny shifts occur with breathing and body position. If CVP rises above this range, it points to higher right-sided filling pressures from causes like fluid overload, right heart failure, tamponade, or pulmonary hypertension. If CVP falls below this range, it suggests reduced venous return, as seen with hypovolemia or dehydration.
