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

• A. 2-6
• B. 0-2
• C. 8-12
• D. 12-16

Answer: (A)

Central venous pressure reflects the right atrial pressure at end diastole and serves as a window into preload and venous return to the heart. A normal value is about 2–6 mmHg. Values within this range suggest adequate preload for most pediatric patients. If the CVP drops below this range, it points toward reduced venous return or hypovolemia; if it rises above, it can indicate fluid overload, increased right-sided pressures, or factors like elevated intrathoracic pressure from ventilation. Remember that CVP readings can be influenced by how the line is zeroed, patient position, and ventilation, so interpret the value in the broader clinical context.
