Technique allowing continuous hemodialysis and/or hemofiltration, using pump-assisted blood circulation.

SCUF
(Slow continuous ultrafiltration)
Continuous process of fluid removal across a semipermeable membrane provides patient fluid removal by ultrafiltration only. Usually performed at ultrafiltration rates lower than 8 ml/min. No substitution fluid is used.

CVVH
(Continuous venovenous hemofiltration)
Continuous hemofiltration with the aid of a blood pump provides solute removal by convection. It offers high volume ultrafiltration using replacement fluid which can be administered pre-filter or post-filter. The pump guarantees adequate blood flow to maintain required UF rates. Venous blood access is usually femoral, jugular or subclavian using a double lumen cannula.

CVVHD
(Continuous venovenous hemodialysis)
Continuous hemodialysis with the aid of a blood pump and using venous access. It provides solute removal by diffusion. Dialysate is pumped in counter flow to the blood

CVVHDF
(Continuous venovenous hemodiafiltration)
Continuous hemodiafiltration with the aid of a blood pump provides solute removal by diffusion and convection simultaneously. It offers high volume ultrafiltration using replacement fluid which can be administered pre-filter or post-filter. Simultaneously, dialysate is pumped in counter flow to blood.
