Abstract
A disposable set and system for dialysis are disclosed. An example peritoneal dialysis system includes an automated peritoneal dialysis (“APD”) machine comprising a pumping mechanism and a peritoneal dialysis fluid heater. The example peritoneal dialysis system also includes a disposable set comprising a disposable cassette operable with the pumping mechanism and a heater bag operable with the heater. The example peritoneal dialysis system additionally includes a conductivity sensor positioned and arranged to provide feedback to the APD machine. The example APD machine is configured to mix a peritoneal dialysis fluid for treatment in the heater bag using a plurality of peritoneal dialysis constituent fluids. In addition, the example APD machine is configured to use feedback from the conductivity sensor to evaluate the mixed peritoneal dialysis fluid for treatment.
