Question

Jeff has learned from his urologist that his kidney disease has progressed to renal failure and that he must include dialysis in his treatment plan. Because you work on the dialysis unit of the hospital, Jeff has asked you to explain how the hemodialysis machine works. He also asks if the unit is portable so that he can use it at home, if necessary. What will you tell Jeff?

Answer 1

With the development in science and technology, now there is portable dialysis machine as well.

Haemodialysis is basically a system used to clear blood, from toxic or indigestible materials left in body like ammonia, drugs, etc.

In this artery is connected to external tube for transfer of blood from body to dialyser system, i.e; blood when exits body it's pressure is checked, later heparin is added to blood to prevent coagulation of blood outside body, after this blood is pumped into dialyser unit in which blood flows in semipermeable tube, in solution present outside tubes in the dialyser unit, and here toxic materials present in blood moves out of it and enters the surrounding solution. After this that pure blood continue out of dialyser unit, after that it's pressure is checked, along with air trap and air detector is assembled, and at last blood is returned to body in vein.

Dialysate, also called dialysis fluid, dialysis solution or bath, is a solution of pure water, electrolytes and salts, such as bicarbonate and sodium. The purpose of dialysate is to pull toxins from the blood into the dialysate
