Dialysis Low Flux

Dialysis Low  Flux

The term 'flux' refers to the permeability of the membrane in the dialyser (artificial kidney) across which accumulated toxins and excess fluid pass during haemodialysis. In the past, this membrane was made from natural cellulose which has relatively small pores. The 'low-flux' cellulosic dialysers could easily remove the smaller toxins such as urea and creatinine, but larger molecules that are normally removed by normal kidneys were unable to fit through the pores. Modern dialyser membranes are made from synthetic polymers or chemically modified cellulose. The manufacturers of dialysers with synthetic membranes can engineer the size of the pores to be the same size as a cellulosic dialyser or much larger
