| how a hemodialyser works: |
|
Definition
| THE BLOOD IS REMOVED FOR CLEANSING AND RETURNED TO THE BODY WHEN THAT PROCESS IS COMPLETE. THE MACHINE MONITORS THE ARTERIAL PRESSURE AND THE RATE OF FLUID REMOVAL FROM THE BODY. THE DIALYZER IS A LARGE CANISTER CONTAINING THOUSANDS OF SMALL FIBERS THROUGH WHICH THE BLOOD PASSES. DIALYSIS SOLUTION PASSES AROUND THE FIBERS. THE FIBERS ALLOW WASTES AND EXTRA FLUIDS TO PASS FROM THE BLOOD INTO THE SOLUTION WHICH CARRIES THEM AWAY. THE DIALYZER IS SOMETIMES CALLED AN ARTIFICIAL KIDNEY. |
