Hemodialysis filters your blood using a dialysis machine or through a dialyzer. Once you are connected to the machine via your hemodialysis access, blood flows into the machine, gets filtered and is returned to your body. Hemodialysis is performed either at home or in a dialysis center. Home hemodialysis can be performed in the comfort of your own home, either with the help of a care partner or on your own. In-center hemodialysis is performed by a trained team of nurses and technicians.
