Components used during a hemodialysis procedure

What are the components used during a hemodialysis procedure?

The components needed to conduct dialysis include a dialysis machine, a method to access the patient’s arterial and/or venous system, a supply of treated water in order to make dialysate, and the dialyzer.

The dialysis machine consists of two major components:

(1) a blood pump and associated safety equipment for the blood pump to monitor pressures in the system and to ensure that air does not enter the blood circuit; and

(2) a dialysate pump, with associated safety devices to ensure that the dialysate is at the correct temperature, has the correct concentration of electrolytes, and has not been exposed to blood from a leak in the dialyzer membrane.

The dialysis machine uses the blood pump to move blood through the dialysis circuit, from the patient, through the dialyzer, and back to the patient. The patient needs to have some type of access to allow for the rapid movement of blood through the dialysis circuit.

Treated water is needed to make the dialysate used during the dialysis procedure.
