Hemodilaysis

Circulation of the patient's blood through a compartment that contains an artificial semi-permeable membrane that is surrounded by dialysate fluid  which removes excess body fluid by creating a pressure differential between the blood and the dialysate solution.

Dialysis

When dialysis is utilized, the semi-permeable membrane used has pores large enough for waste products and water to move through, but too small for blood cells and protein molecules to pass through.

Chronic Renal Failure

CRF is a progressive, irreversible reduction in renal function such that the kidneys are no longer able to maintain the body environment.  The Glomerular filtration rate gradually decreases as the nephrons are destroyed.

BUN (5-20)

Blood Urea Nitrogen (BUN) lab test is commonly used to diagnose renal problems. It may be affected by an increase in protein intake or tissue breakdown.
