Abstract
During hemofiltration, blood is conveyed from an individual through a blood line into a hemofilter to remove waste fluid. Waste fluid is conveyed from the hemofilter through a waste removal line at a waste removal rate. Waste fluid pressure is sensed in the waste removal line. A controller adjusts the waste removal rate to maintain waste fluid pressure at a predetermined set value.
