Comparison of selected intravenous infusion pumps and rate regulators.
Selected intravenous infusion pumps and rate regulators were compared to determine the relative advantages and disadvantages and to formulate guidelines for purchase of these devices. Three basic types of devices were studied: infusion rate regulators, nonvolumetric (peristaltic) infusion pumps and volumetric infusion pumps. Simple syringe-type infusion pumps were not studied. After use and close study of the devices, both in the laboratory and in the clinical area, desirable features were identified. Ideally, the infusion device should operate over a wide rate range, use standard administration sets, be easy to assemble and service, have an internal battery of good power for several hours, have appropriate malfunction alarms, have an automatic keep-open device in alarm situations, be accurate under a variety of situations, and be easy for the nurse to understand and operate. All devices tested were accurate within the limits claimed by the manufacturer, although a couple of models have features which can cause gross volume errors. Overall evaluation resulted in preference of some devices over others. Cost of infusion devices and administration sets can vary widely, and this should be a factor in the final choice of intravenous infusion equipment.
