Method
Pumps, cartridges and infusion protocols
The experiment were carried out using several iPRECIO® Dual pumps and cartridges/cassettes.
Where possible/appropriate the total number of points, n is shown with the results.
Continuous infusion, intermittent and bolus accuracies were tested.
Assessment Procedure
The infusion flow-rate was determined by measuring the weight change of a bottle collecting infusate from the outlet of the iPRECIO® Dual pump.
An analytical balance was used and the results were automatically recorded on a PC.
Result
Flow Accuracy Test (High & Low Flow)
Bolus Infusion Test (High & Low Flow)
