Plasma electrolyte management system, methods, and apparatus for continuous renal replacement therapies (RRT) are disclosed. The example system, methods, and apparatus use one or more kinetic physiological models to calculate a current electrolyte rate of change in plasma sodium or other electrolytes based on current data for patient weight, input/output of water, sodium, and potassium (e.g., input/output of known infusions, dialysis, urine, blood loss, etc.) This input/output data is acquired through known data, such as infusion data, dialysis data, urine data, and blood loss data, which are typically stored to a patient's electronic medical record (“EMR”) as the data is generated/received. The use of available point-in-time input/output data to generate accurate electrolyte concentration estimations means that fewer (or none) blood tests are needed, thereby providing accurate electrolyte determinations without frequent burdensome blood analyses.
