CVVHDF: Continuous VenoVenous HemoDiaFiltration

Description

CVVHDF is a combination of hemofiltration and hemodialysis which can be preferred to these 2 methods. Reasons for this are, for example, the higher clearance of medium size substances when compared to hemodialysis or less dependence on blood flow when compared to hemofiltration.

Examples of application

Technical information

In CVVHDF, blood is passed through a hemofilter while dialysate is injected on the other side of the semi-permeable membrane thus combining the filtration process to the dialysis one. In CVVHDF, substitution fluid must be injected in the blood to compensate for the filtration flow.
