Abstract
A blood filtration system may to couple to an infusion pump that is external to the blood filtration system. The blood filtration system may include a blood circuit, for instance a variable-volume blood circuit. An infusion port may be in communication with the blood circuit and may receive an infusion fluid pumped by the infusion pump. A filtration pump may extract a filtrate fluid from a filter. The filtrate fluid may include filtered plasma constituents. A fluid characteristic sensor may measure one or more of pressure or flow rate of the infusion fluid pumped by the infusion pump. A controller may monitor the fluid characteristic sensor to determine a change in the pressure or flow rate of the infusion fluid. The controller may modulate a speed of the variable-speed filtration pump based on the change in the pressure or flow rate of the infusion fluid.
