An infusion system (10) controlling for the optimum flow rate of a first infusate relative to a second infusate is disclosed. The system (10) comprises a first delivery unit (14) that delivers a first infusate to an infusion circuit (34), a second delivery unit (16) that delivers a second infusate to the infusion circuit (34), a measurement device that determines an amount of undelivered first infusate remaining to be infused and a control system (12). The control system (12) controls delivery of the first infusate from the first delivery unit (14), enables input of a predetermined volume of the first infusate to be delivered and input of a predetermined time period for infusion of the predetermined first infusate volume. It then determines a time remaining in the predetermined infusion time period then communicates with the first delivery unit (14), the second delivery unit (16), and the measurement device to determine a first infusate infusion flow rate based on the predetermined first infusate volume, the predetermined infusion time period, the determined amount of undelivered first infusate remaining in the system and the determined time remaining in the predetermined infusion time period. The controller (12) is also able to recalculate the first infusate infusion flow rate after any interruptions of either the first (14) or the second (16) delivery units and controls the first delivery unit (14) to deliver the first infusate at the determined first infusate infusion flow rate. |
