Abstract: The invention relates to devices, systems, and methods for calculating a bicarbonate concentration in a fluid used in dialysis. The devices, systems, and methods can be used to calculate the bicarbonate concentration in either dialysate or blood. The invention measures the amount of carbon dioxide in both an acidified and non-acidified solution and calculates the bicarbonate concentration based on the difference in carbon dioxide concentrations.

Abstract: The invention relates to devices, systems, and methods for managing base levels, specifically bicarbonate, in an individual undergoing dialysis. The devices, systems, and methods can be compatible with a sorbent-based dialysis therapy, and open loop control of base levels in the dialysis, without sensors or feedback for controlling the introduction of bicarbonate into the dialysate. The bicarbonate levels can be controlled and personalized to a patient using certain predetermined patient parameters. Related systems, algorithms, and control systems are contemplated including the specific predetermined parameters predictive of post-dialysis bicarbonate levels.
