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.
A normal hemodialysis run is about 3-4 hours, while a normal SLED run is about 8 hours. The blood moves more slowly through the system with a slower ultrafiltration rate, which allows us to do dialysis on our more unstable patients who will not tolerate the fluid shifts of traditional hemodialysis.
