Hemodialysis is when your blood travels through plastic tubing to a special filter (dialyzer) which functions as an artificial kidney. At the start of your hemodialysis journey, a dialysis access will be placed. You and your physician will discuss the best access for you.
During hemodialysis, the blood will travel to the dialyzer by means of needles connected to your blood vessels. This dialyzer cleans your blood of waste products and extra fluid, and your clean blood is returned to you. This can be done in the comfort of your own home or at one our 8 dialysis locations.
