A system and method for balancing flows of renal replacement fluid is disclosed. The method uses pressure controls and pressure sensing devices to more precisely meter and balance the flow of fresh dialysate and spent dialysate. The balancing system may use one or two balancing devices, such as a balance tube, a tortuous path, or a balance chamber.

The present invention concerns an extracorporeal circuit for removing CO.sub.2 from blood comprising a blood withdrawal line for withdrawing blood from the patient, a filtration unit for producing plasma water and a line for returning the blood to the patient, defining a main circuit; the extracorporeal circuit further comprises a decarbonating group comprising a secondary circuit for the recirculation of plasma water, means for removing a fraction of said plasma water, a CO.sub.2 exchanger, a cationic resin charged with H+ ions set upstream of the CO.sub.2 exchanger and adapted to generate acid plasma water, means for the infusion of the acid plasma water upstream of the CO.sub.2 exchanger and means for the infusion of ions in a solution downstream of the CO.sub.2 exchanger.

A method of preparing a solution for use during a dialysis, hemodialysis, or Continuous Renal Replacement Therapy (CRRT) treatment of a patient is provided. An antibiotic or other drug is added (48, 50, 52) to a solution and the concentration or dosing of the antiboitic or other drug within the solution is adjusted (72) as required based on a determiniation (64) of serum level of the antibiotic in a blood sample of a patient.

The specification discloses a portable dialysis machine having a detachable controller unit and base unit with an improved reservoir heating system. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a reservoir with an internal pan and external pan, separated by a space that holds a heating element. The heating element is electrically coupled to electrical contacts attached to the external surface of the external pan.

Systems, methods, and/or apparatuses may be operative to perform a dialysis process that includes a displacer infusion process. The dialysis machine may include at least one processor and a memory coupled to the at least one processor, the memory comprising instructions that, when executed by the processor, may cause the at least one processor to access dialysis information for a dialysis process performed by a dialysis machine, the dialysis information indicating a target substance to be displaced from a binding compound by a displacer, and determine an infusion profile for infusing the displacer into a patient during a displacer infusion process of the dialysis process, the infusion profile determined based on the dialysis information and an infusion constraint. Other embodiments are described.
