ABSTRACT:
A method of adjusting the final conductivity of a batch of dialysate to bring the conductivity down to a desired level is described. The batch of dialysate is prepared by mixing excess quantities (e.g., 5%) of dialysate solution chemicals with water to form a solution with a conductivity greater than that required for the particular batch. A measurement of the dialysate solution is taken. A precise volume of water is added to the dialysate solution to dilute the dialysate to the proper level. The precise volume of water is calculated from a known or estimated total system, the desired conductivity level and the actual conductivity. The resulting diluted dialysate is at the desired conductivity level. Excess dialysate which may be present in the dialysate circuit or associated tanks is then flushed to a drain. In a hemodialysis embodiment, the excess dialysate may be flushed through the dialyzer into the blood lines to rinse any pyrogens from the extracorporeal circuit.
