Hemodialysis: In hemodialysis, a dialysis machine and a special filter called an artificial kidney, or a dialyzer, are used to clean your blood. To get your blood into the dialyzer, the doctor needs to make an access, or entrance, into your blood vessels. This is done with minor surgery, usually to your arm.
Where can hemodialysis be done? Hemodialysis can be done in a hospital, in a dialysis center that is not part of a hospital or at home. You and your doctor will decide which place is best, based on your medical condition, and your wishes.

Studies show that the more you know about your treatment and the more you do on your own, the better you are likely to do on dialysis.
