What is different between apheresis and dialysis?

Answer 1

Dialysis is the process of replacing kidney function. Diffusion is just the natural tendency of things to move from higher concentration to lower concentration. Example: You have two identical rooms next to each other and one is filled with smoke and the other is not. Now imagine there is a door that conects these two rooms together. What would happen if you opened the door? The smoke would move towards the smokeless room and clean air would rush into the smoke filled room until there is equal amount of smoke in both rooms. How does this apply to dialysis? The artificial kidney has two chambers one is for the blood (this includes the inside of the membrane) and the other is for dialysate (cleansing fluid). The blood flows through the membrane in one direction and the dialysate flows through the artificial kidney in the opposite direction. The membrane, wich is basically a large bundle of small tubes with a bunch of tiny holes all along the outside of it, (holes that are too small to let blood vessels escape, but will allow waste particles to escape) allows the cleansing of the blood by diffusion. Example, if the potassium in your blood is at 5.5 and the potassium in the dialysate is 2.0 what do you think will happen to the potassium level in the blood? Remember the smoke filled room? Any dialysis professional would say that there is way more to it than that, and they are right, but I have tried to put it in a nutshell and in layman's terms.

Answer 2

Diffusion Dialysis is a membrane separation process which has been successfully used for many years for the separation and recovery of acids from dissolved metal bearing solutions. Mech-Chem's

diffusion dialysis systems

are fully automated making them simple and economical to operate.

Answer 3

both are same simillar procedure dialysis technician do apheresis easily
