Both peritoneal dialysis and hemodialysis pass blood through a membrane to filter out waste products and fluid into dialysate . Dialyzer A plastic artificial kidney that contains thousands of very thin, hollow, tube-like membrane fibers.
Blood flows through the inside of the hollow membranes.
The fibers are surrounded by dialysate. Toxins from the blood move through the membranes and into the dialysate. The blood remains inside the hollow tubes and is returned to the body, once cleaned. Disequilibrium Headaches and dizziness during dialysis. Disequilibrium can occur if dialysis removes a lot of fluid very quickly, or if blood pressure drops.
