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

0-2 mm Hg
2-6 mm Hg
6-10 mm Hg
10-15 mm Hg

The correct answer is: 2-6 mm Hg

The expected central venous pressure (CVP) range is typically between 2-6 mm Hg. This measurement reflects the pressure in the thoracic vena cava near the right atrium, which is an indicator of the volume status and right heart function of a patient. A CVP within this range suggests adequate blood volume and proper cardiovascular function, allowing healthcare providers to assess fluid balance and guide treatment for conditions such as heart failure or shock. Values below this range may indicate hypovolemia, while values above it could suggest fluid overload or right-sided heart failure. Monitoring CVP can be crucial in critically ill patients who require careful management of their fluid status and hemodynamics.
