What is the primary delivery system for dialysis?

The primary delivery system for dialysis is the hemodialysis machine, which plays a critical role in the dialysis process. This machine is designed to effectively remove waste products and excess fluids from the blood of patients with kidney failure.

The hemodialysis machine works by connecting to the patient’s vascular access, allowing their blood to be drawn out, filtered through a dialyzer (which acts as an artificial kidney), and then returned to their body. This continuous cycle is essential for maintaining the patient’s health by ensuring that toxins and excess electrolytes are removed from the bloodstream.

In this context, while the dialyzer is a crucial component of the process, it is the machine itself that provides the necessary system to control the flow of blood and dialysate, as well as to monitor the patient's vital signs and ensure the safety and effectiveness of the treatment. The patient's own blood flow alone is not sufficient for the dialysis process, and a transfusion system does not serve the same purpose as the hemodialysis machine in filtering blood.
