Method and Systems for Controlling Ultrafiltration Using Central Venous Pressure Measurements

摘要

The volume of fluid removed from a patient during ultrafiltration is controlled automatically on the basis of central venous pressure (CVP) measurements. In one embodiment, a central venous catheter (CVC) is used for accessing blood during dialysis. A sensor located at the tip of the catheter or inside the dialysis machine is used to periodically measure CVP. CVP feedback data helps prevent the excessive removal of fluids from the patient.
