Where is a CVP line typically sited?

• A. In the right atrium via the subclavian vein
• B. In the superior vena cava via the internal jugular vein
• C. In the femoral vein
• D. In the inferior vena cava via the external jugular vein

Answer: (B)

The central venous pressure (CVP) line is typically placed in the superior vena cava via the internal jugular vein due to the anatomy of the vascular system. This site allows for efficient access to the central venous system, enabling accurate measurement of intravascular volume status and monitoring of cardiac output. The internal jugular vein is easily accessible and provides a direct route to the superior vena cava, where the CVP can be accurately measured, reflecting the pressure in the right atrium and overall cardiac function. Other sites listed, such as the right atrium via the subclavian vein, the femoral vein, and the inferior vena cava via the external jugular vein, are less conventional for CVP monitoring, either because they do not provide direct access to the central venous system or because they pose increased risks of complications. Thus, the option involving the placement in the superior vena cava via the internal jugular vein is both the most common and clinically effective approach for CVP line placement.
