The fistulas a good deal have to be replaced several time over the lifetime, and thither are a limited number of places where they can be inserted, e.g. wrists, legs, chest.

Hemodialysis involves circulating the patient's blood

through an extracorporeal circuit (Smith, 2005). devil needles are inserted into the fistula and attached to tubing, which circulates the blood through the drip and back to the patient. The blood is separated from the dialysate by a semipermeable membrane which bothows molecules of a certain size to pass through. ocellus flows in one direction and dialysate in the other in a countercurrent. The opposing pressures drain excess fluid from the blood stream into the dialysate. Waste products in the blood diffuse out of the bloodstream into the dialysate and electrolytes from the dialysate diffuse into the blood.

However, they need to negate heavy physical labor so may have to change their occupation to something less strenuous.
