An apparatus for extracorporeal treatment of blood comprising: a filtration unit having a primary chamber and a secondary chamber separated by a semi-permeable membrane; a blood withdrawal line connected to an inlet of the 5 primary chamber, and a blood return line connected to an outlet of the primary chamber said blood lines being configured for connection to a patient cardiovascular system; a blood pump configured to control the flow of blood through the blood lines; an effluent fluid line connected to an outlet of the secondary chamber; at least two further fluid lines selected in the group comprising: a pre-dilution infusion fluid line connected at one end thereof to the blood withdrawal line, a post-dilution infusion fluid line connected at one end thereof to the blood return line, a dialysis fluid 10 line connected at one end thereof to the inlet of the secondary chamber, a pre-blood pump infusion fluid line connected at one end thereof to the blood withdrawal line in a region of this latter which is positioned in use upstream the blood pump, means for regulating the flow of fluid through said fluid lines; and a control unit connected to the means for regulating, the control unit being configured to execute a flow-rate setup procedure comprising: allowing entry by an operator of the set value for at least a first fluid flow rate selected in the group including: a fluid flow rate 15 through the pre-dilution infusion fluid line, a fluid flow rate through the post-infusion fluid line, a fluid flow rate through the pre-blood pump infusion fluid line, a fluid flow rate through the dialysis liquid fluid line, and a fluid removal rate from the patient, allowing entry of a set value for a prescribed dose to be delivered, calculating set values of at least a second and a third of the fluid flow rates of said group of flow rates, based on the said first fluid flow rate set by the operator and on said prescribed dose value. 8216845_1 (GHMatters) P96324.AU.1 QBLOOD-SET DPFR RECIVE SET VALUE Dose SELECTION OF 201 R1, R2, R3 202 SELECTION OFCONFLIT OPTIMIZATION <CHK CALCULATION OF 203 FLOW RATES 205 CONTROLPUMPS WITH CALCULATED |
