Continuous venovenous hemofiltration is used to:
a. remove fluids and solutes through the process of convection.
b. remove plasma water in cases of volume overload.
c. remove plasma water and solutes by adding dialysate.
d. combine ultrafiltration, convection and dialysis.
A
Continuous venovenous hemofiltration (CVVH) is used to remove fluids and solutes through the process of convection. Slow continuous ultrafiltration (SCUF) is used to remove plasma water in cases of volume overload. Continuous venovenous hemodialysis (CVVHD) is similar to CVVH in that ultrafiltration removes plasma water. It differs in that dialysate solution is added around the hemofilter membranes to facilitate solute removal by the process of diffusion. Continuous venovenous hemodiafiltration (CVVHDF) combines ultrafiltration, convection, and dialysis to maximize fluid and solute removal.
