Central Venous Pressure Monitoring. Normal Sternum: 0–14 cm H2O, Midaxillary line: 8–15 cm H2O. CVP can be measured by connecting the patient's central venous catheter to a special infusion set which is connected to a small diameter water column. If the water column is calibrated properly the height of the column indicates the CVP. In most intensive care units, equipment is available to measure CVP continuously. Normal range for CVP is 3–12 cm water pressure


Central Venous Pressure (CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system. CVP is often a good approximation of right atrial pressure (RAP),[1] although the two terms are not identical, as a pressure differential can sometimes exist between the venae cavae and the right atrium. CVP and RAP can differ when arterial tone is
