Dialysate

Dialysate is a chemical bath used in dialysis to draw waste products out of the blood and supply electrolytes. It is composed of purified water, electrolytes, and a buffer. The composition of the dialysate is carefully controlled to facilitate the removal of various waste products from the blood.

Composition

The dialysate is composed of several components, including:

• Water: The water used in dialysate is purified to remove any impurities that could harm the patient.
• Electrolytes: These are minerals that carry an electric charge and are found in your blood and body fluids. They help balance the amount of water in your body, move nutrients into your cells, and move wastes out of your cells.
• Buffer: A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.

Function

The primary function of the dialysate is to help remove waste products from the blood in patients with kidney failure. The dialysate flows on one side of a semi-permeable membrane in the dialysis machine, while the patient's blood flows on the other. Waste products in the blood cross the membrane into the dialysate, which is then discarded.
