A serious question, by "testing" do you mean performing a verification, a check, or a calibration?
Alaris Infusion Pumps have a dedicated performance verification procedure, (additional testing and calibration may be required after certain repairs are completed).
If the dedicated test equipment is not available, you use what you have to hand in the workshop to check equipment. This can be a stopwatch and burette, a set of scales (gravimetric method), a manometer, or an Infusion Device Analyser. Note, the IDA4, is not a Calibrator, but can be used to independently check infusion device function.
There is a subtle difference between, check, verify, and calibrate.
You can develop your own testing regime or protocol based upon manufacturer recommendations, and your knowledge, (so long as you have traceability and can confirm that equipment is performing within manufacturers specifications). No-one will ever be criticised for adhering strictly to manufacturers recommendations, but budget and time constraints force innovative testing solutions to be developed.
Where you deviate from manufacturer recommendations, document, risk assess, and get signed off.
