Using a high flux filter at low UF rates
produces backfiltration at the dialysate
inlet of the filter. This backfiltrated fluid
serves as a substitution fluid. The patient‘s
fluid balance is maintained by the Diapact®
CRRT System’s single weigh scale.
The result of this therapy (CVVHFD —
Continuous Veno-Venous High Flux Dialysis)
is a combination of convective and diffusive
clearances combined with the middle
molecule clearance capability of the high
flux filter.
