This reduces the disadvantages and combines the advantages of the
separate procedures. Depending on the application conditions, the
treatment can thus be optimised. For example, Post CVVHDF makes it
possible to select the highest possible filtrate flow relative to the
achievable blood flow and still keep haemoconcentration in the filter to
within acceptable limits. The dialysis component of a Post CVVHDF
procedure further increases the treatment efficacy without additional
blood flow requirements, as the filtration fraction (UFR / BPR) is not
affected by this.
