Infusion pump analyzers

Infusion pump analyzers are test devices that aid in determining the performance of infusion pumps. These devices perform simple flow tests, and in some instances volume and occlusion pressure tests as well, that otherwise would be performed using burettes or other calibrated glassware, balances, timers, and pressure meters or gauges. We evaluated five models from four different suppliers, focusing primarily on performance and human factors design. Three units were rated Acceptable, and two were rated Acceptable--Not Recommended because of performance limitations and, for one of the units, poor human factors. This Evaluation includes an overview of infusion pump analyzer technology and a Selection Guide detailing the factors that facilities should consider when purchasing an infusion pump analyzer. In addition, a supplementary article discusses recertification systems, which are designed for testing home-use pumps before use on each new patient. Another supplementary article deals with trumpet curves, a capability that may have limited value for most users.
