Pump Accuracy Testing - Abbott FreeGo Manual De Uso

PUMP ACCURACY TESTING

There are many variables that can affect flow rate, such as fluid head height and
fluid viscosity. The Abbott FreeGo pump system has been optimized for delivery
accuracy when using Abbott Nutrition 1.0 kcal Ready-To-Hang (RTH) feeding
formulas. To check flow rate accuracy, use the following procedure:
1. Select a new Abbott FreeGo feeding set for this test. Be sure to use
a graduated cylinder for volume measurement—not an enteral container or
other uncalibrated vessel.
2. Use an Abbott Nutrition feeding formula in a Ready-To-Hang (RTH)
container and set up pump according to INSTRUCTIONS FOR USE.
3. Suspend feed container to side or behind the pump. Recommended head
height is 30 cm from the center of the rotor to the top of the fluid in feed
container.
4. With the test pump connected to AC/Mains, set the rate to 84 mL/hr.
5. Run fluid into graduated cylinder for 8 hours and compare the accumulated
volume in the graduated cylinder to chart below.
FLUJO (SET RATE)
84 mL/hr
If the amount in the graduated cylinder is incorrect based on FLUJO (SET RATE), try a new Abbott
FreeGo feeding set and repeat the procedure.
The diagram below describes how variation from recommended head height affects flow rate accuracy.
