SYSTEMS AND METHODS FOR INCORPORATING PATIENT PRESSURE INTO MEDICAL FLUID DELIVERY

Abstract:

Systems and methods are disclosed for incorporating patient pressure into medical fluid delivery. An example system includes a medical fluid delivery machine and a medical fluid handling device including a patient line for being placed in fluid communication with a patient. The medical fluid delivery machine includes a control unit, a pump actuator for actuating the medical fluid handling device to move medical fluid into or out of the device, and a pressure sensor configured to sense a pressure of the medical fluid. The control unit is programmed to perform a routine during pumping in which the control unit determines if at least a component of a signal reading from the pressure sensor is indicative of a pressure within the patient, and determines from the component of the signal reading indicative of the pressure in the patient whether to continue pumping or stop pumping.
