Fig. : Flow Diagram Pressure Reduction VDABK with UFP
The pressure at PDA is reduced built-up to
≤
380 mmHg with the UF pump
after the dialyser test circuit is closed. The UF pump is driven with 3000 ml/h.
VDA is closed during this pressure reduction. Thus the UF pump strokes are
damped via the extended flow path and no interferences are generated at PDA.
