Nurse preparing male patient to use a kidney machine to undergo renal dialysis. A kidney machine replaces the function of the kidneys in removing waste materials from the bloodstream. A stream of blood from an artery is circulated through the machine on one side of a semi-permeable membrane,while a solution of comparable electrolytic concentration circulates on the other side. Water and waste products pass across the membrane but blood cells and proteins are too large to do so. Purified blood is returned to the patient through a vein | |
