Background

Central Venous Pressure (CVP) refers to the pressure in the right atrium and the thoracic segments of the superior and inferior vena cava. It can judge the comprehensive condition of blood volume, cardiac function and blood vessel tension of patient, and is different from peripheral venous pressure. The latter is affected by the valves in the venous lumen and other mechanical factors, and therefore cannot reflect the blood volume and cardiac function exactly. The magnitude of the cardiac venous pressure depends on the correlation between the ability of the heart to eject blood and the amount of venous return. If the heart has strong blood ejection capability, the blood returning to the heart can be ejected into the artery in time, and the central venous pressure is low. Conversely, a decrease in ejection capability due to heart failure or the like will result in an increase in central venous pressure. The determination of the central venous pressure is of great significance to the understanding of effective circulating blood volume and cardiac function. Currently, central venous pressure is typically measured by a central venous pressure measurement tube.
