The application discloses a two-compartment modeling and prediction method for sodium kinetics in hemodialysis. The method divides the patient's body fluid into two compartments of extracellular fluid and intracellular fluid, and establishes a coupled differential equation set to describe the sodium transfer kinetics in the dialysis process. The application corrects the physical error of the existing model in the dispersion equilibrium concentration formula, proposes C_eq=[Na]d / σ (σ=0.97 is the Gibbs-Donnan factor) to replace the traditional Donnan formula and the old recommended formula, eliminates the false dispersion gradient under the condition of isonatric dialysis based on the physical fact that electrolytes are only distributed in the plasma water phase, and removes the error solvent drag term by clearly defining the biophysical constraints of the cell membrane aquaporin not transporting sodium. The application adopts a perturbation reference model to replace the traditional Fick diffusion law to describe the cell membrane sodium exchange, and more accurately reflects the intracellular and extracellular sodium kinetics. The model can accurately predict the serum sodium change and sodium removal under different dialysis prescriptions, and can generate a sodium removal contour map for clinical prescription optimization.
