Modern infusion pumps: are they accurate?

This study examined the volumetric accuracy of six infusion pumps currently available in Canada. Volumes delivered by all pumps over a range of 20-200 ml an hour were within five per cent of their indicated values. The pumps proved to be consistent and unaffected by the height of the infusion bag above the pump or by differing cannulae sizes. A discussion of some of the infusion methods for obtaining clinical accuracy is included.
