A new approach to individualize dialysis fluid sodium concentration using a four-stream, bicarbonate-based fluid delivery system

We propose a new 45X, four-stream, triple-concentrate, bicarbonate-based dialysis fluid delivery system, allowing a wide range of dialysis fluid sodium concentrations\\ (DFNa) without affecting the concentrations of other crucial solutes. The four streams consist of product water (W), and concentrates with sodium chloride (S), acid (A), and sodium bicarbonate (B). An adjustment in the DFNa in this new system requires changes only in the W and S concentrate streams. The ingredients in A and B concentrates do not change.

Automated summary

The proposed new dialysis fluid delivery system allows for a wide range of dialysis fluid sodium concentrations without affecting other crucial solutes, by adjusting product water and sodium chloride concentrate streams while keeping the acid and sodium bicarbonate concentrate ingredients constant.
