Ultrafiltration is the part of the hemodialysis process where fluid is removed from the bloodstream and is often done with the sole purpose of taking fluid off when diuretics aren't doing the trick, or the kidneys have taken a hit and need relief from fluid overload. SLED is hemodialysis at a slower rate.
In continuous venovenous hemodialysis (CVVHD, Figure 2 â), diffusion and ultrafiltration are used to remove waste products. The fluids used are known as dialysate fluids. Dialysate is infused countercurrent to the blood flow, into the outside compartment of the hemofilter to provide a diffusion of wastes from the blood.
