The infusion monitor is adapted to operate at a high speed or a low speed in dependence upon a variable characteristic of the patient, such as weight. If during infusion, the weight of the patient deviates from a preset value the infusion monitor speed is changed. For example, with the infusion monitor operating at the normal low speed, if the weight decreases, the infusion monitor is switched to the high speed. When the weight subsequently returns to the preset value, the infusion monitor switches back to the low speed.
