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

Central venous pressure (CVP) is a critical measurement used to assess the hemodynamic status of a patient, particularly in critically ill individuals. The normal range for CVP is typically between 2-6 mmHg, which indicates the pressure in the thoracic vena cava near the right atrium of the heart. This measurement helps clinicians evaluate the patient's fluid volume status and cardiac function.

A CVP within this normal range suggests that there is adequate venous return to the heart and sufficient preload for optimal cardiac output. Values below this range may indicate hypovolemia, while higher values could suggest fluid overload or increased central venous pressure due to right heart dysfunction.

Monitoring CVP can be particularly useful in guiding fluid therapy and managing patients in critical care settings, especially those with conditions like shock, heart failure, or severe sepsis.
