Central venous pressure

Central venous pressure refers to the pressure of the superior or inferior vena cava. The central vein reflects to a certain extent the comprehensive status of the patient's effective blood volume, cardiac function and vascular tone at the time of pressure measurement. Therefore, continuous measurement of changes in central venous pressure can dynamically understand changes in blood volume and judge the heart's tolerance to fluid replacement, which is an important reference index for regulating infusion therapy.
