Phosphorus removal with a variable chloride, CO₂ acidified dialysate using an unmodified single pass system

A method of providing dialysate employing CO₂ gas that can be used on a standard unmodified dialysis machine was recently developed. The objective of this study is to test the technical feasibility of the dialysate delivery system and to determine whether use of the dialysate could influence mass phosphorus removal. This system was designed to be acetate free and has the capability of increasing serum chloride concentration above those normally achieved during the early phases of dialysate. Although considerable evidence existed regarding the intracellular shift of phosphorus caused by acetate metabolism, no benefits were achieved with respect to mass prosphorus removal.
