	Definition:		In this type of dialysis, the patient's blood is passed through a tube into a machine that filters out waste products. The cleansed blood is then returned to the body. Hemodialysis is performed by extracorporeal circulation of the patient's blood such that the dialysate solution and the blood is separated only by a thin membrane which allows water soluble molecules to exchange. Since the dialysate contains low concentration of many of the toxic metabolites and potassium, this method effectively lowers the concentration such molecules in blood.
