PROMETRA® II PROGRAMMABLE PUMP
Page 36 of 38
Flow Rate Accuracy
Although it is strongly recommended to program the low reservoir volume alarm to 2 mL, it is
important to know that reservoir volume down to 1 mL will not affect the operation of the pump. This
margin of safety was designed to offer your patients an additional measure of comfort and safety.
Pump flow rate accuracy was evaluated at multiple infusion rates (≈0.05mL/day – 28.8mL/day), at 37°c
body temperature, utilizing both constant flow and variable flow regimes.
