Comparative StudyThe performance of three portable infusion-pump devices set to deliver 2 mL/hr.
The performance of three portable infusion-pump devices set to deliver 2 mL/hr was studied. Portable infusion-pump devices (CADD-1, Paragon, and Singleday Infusor) were set to deliver 5% or 25% dextrose in water at 2 mL/hr for 24 hours at two environmental temperatures (25 and 35 degrees C). There were a total of 12 types of experimental runs, and each run was performed in triplicate. ⋯ Mean flow continuity was significantly higher for the 5% dextrose solution and for the 25 degree C temperature. Flow continuity differed among three representative portable infusion-pump devices set to deliver 2 mL/hr, but flow rate accuracy did not. Fluid viscosity, environmental temperature, and elapsed time affected flow rate accuracy and flow continuity.
