| Abbreviation / other names What
does |
Renal Machine, Dialysis Machines Haemo = blood |
| What does it do? |
Decontaminate the blood Maintain liquid balance Maintain electrolyte balance |
| Physiology |
Replacing the function of the failed kidneys |
| How it works |
Solutions are mixed with reverse osmosis(RO) water to create
dialysate (cleansing fluid). The dialysate is heated to 37C,
de-aerated and passed through the dialyser (artificial kidney),
where the blood is cleaned by osmosis, diffusion, and ultra-filtration.
Anti clotting agents are used to prevent dialyser blockages.
Waste fluid is pumped to drain. |
