HEMOFILTRATION:
It is a similar treatment hemodialysis,but it makes use of a different principle.The blood is pumped through a hemofilter or a dialyser as in dialysis ,but no dialysate is used.A pressure gradient is applied ;as a result;water moves across the very permeable membrane rapidly,dragging with it many dissolved substances,importantly noes with large molecular weights which are cleared well by hemodialysis.Salts and water lost from the blood during this process are replaced with a substitution fluid that is infused in to extracorporeal circuit during the treatment.
