A CVP reading of which value would fall within the normal range (2-8 mmHg)?

A CVP reading of which value would fall within the normal range (2-8 mmHg)?

• A. 12 mmHg
• B. -1 mmHg
• C. 20 mmHg
• D. 6 mmHg

Answer: (D)

Central venous pressure reflects the pressure in the right atrium and serves as a gauge of preload. The normal range for CVP is 2–8 mmHg. A measurement of 6 mmHg falls within that range, indicating normal right-sided preload and venous return at this moment. Values higher than normal, such as 12 or 20 mmHg, point to elevated right atrial pressure from fluid overload, right heart dysfunction, or conditions like tamponade or pulmonary hypertension. A value like -1 mmHg isn’t a typical physiologic CVP reading and would usually suggest a measurement error or abnormal setup. So, 6 mmHg is the normal reading.
