Hemodialysis is a treatment to filter wastes and water from your blood, as your kidneys did when they were healthy. Hemodialysis helps control blood pressure and balance important minerals, such as potassium, sodium, and calcium, in your blood.
Hemodialysis can help you feel better and live longer, but it’s not a cure for kidney failure.
What happens during hemodialysis?
During hemodialysis, your blood goes through a filter, called a dialyzer, outside your body. A dialyzer is sometimes called an “artificial kidney.”
At the start of a hemodialysis treatment, a dialysis nurse or technician places two needles into your arm. You may prefer to put in your own needles after you’re trained by your health care team. A numbing cream or spray can be used if placing the needles bothers you. Each needle is attached to a soft tube connected to the dialysis machine.

Blood flows past another pressure monitor before entering the dialyzer, or filter. Filtered blood continues past a venous pressure monitor, an air trap and air detector, and an air detector clamp, and returns to your arm.
During hemodialysis, your blood is pumped through a filter, called a dialyzer.
The dialysis machine pumps blood through the filter and returns the blood to your body. During the process, the dialysis machine checks your blood pressure and controls how quickly
