1. A dialysis system comprising:
- a dialysis machine;
an infusion pump housed external to the dialysis machine; and
an infusion pump controller in operable communication with the infusion pump, wherein the dialysis machine includes;
a blood pump housed within the dialysis machine;
a dialysis fluid pump housed within the dialysis machine;
a filtrate pump housed within the dialysis machine;
a dialysis machine controller in operable communication with the blood pump, the dialysis fluid pump and the filtrate pump;
a dialyzer, arterial and venous blood lines in fluid communication with the dialyzer, the blood pump positioned and arranged to pump blood within the arterial and venous blood lines;
a dialysis fluid line in fluid communication with the dialyzer, the dialysis fluid pump positioned and arranged to pump dialysis fluid within the dialysis fluid line;
a spent dialysis fluid line in fluid communication with the dialyzer, the filtrate pump positioned and arranged to remove ultrafiltration via the spent dialysis fluid line; and
an infusion line in fluid communication with one of the arterial and venous blood lines, the infusion pump positioned and arranged to pump an infusion solution within the infusion line;
whereinthe dialysis machine controller is in operable communication with the infusion pump controller to automatically synchronize operation of the infusion pump to the blood pump or the filtrate pump.
