In medicine, hemodialysis, also haemodialysis, is a method for removing waste products such as potassium and urea, as well as free water from the blood when the kidneys are incapable of this (i. e. in renal failure). It is a form of renal dialysis and is therefore a renal replacement therapy.

Hemodialysis is typically conducted in a dedicated facility, either a special room in a hospital or a clinic (with specialized nurses and technicians) that specializes in hemodialysis. Are you diabetic? Do you have Medicare or private insurance? If so, you could

Home hemodialysis has numerous advantages over in-center dialysis, such as greater patient control over the therapy and better symptom control due to longer and/or more frequent dialysis sessions.

The principle of hemodialysis

The principle of hemodialysis is the same as other methods of dialysis; it involves diffusion of solutes across a semipermeable membrane. In contrast to peritoneal dialysis, in which transport is between fairly static fluid compartments, hemodialysis relies on convective tranport and utilizes counter current flow, where the diasylate is flowing in the opposite direction to blood flow in the extracorporeal circuit. Counter-current exchanges maintain the concentration gradient across the membrane at a maximum and increase the efficiency of the dialysis. Owens & Minor Acquires Access Diabetic Supply.
