Accuracy of infusion flow rates and bolus doses for portable infusion pump.

ABSTRACT: This study aimed to investigate the flow rate accuracy and bolus doses of four portable pumps with different mechanisms. We evaluated two electronic (COOPDECH Amy PCA [Amy] and CADD-Solis) and two elastomeric balloon-type pumps (COOPDECH Balloonjector and Rakurakufuser) under the following conditions: placement with an epidural catheter, operation on a shaking table, warming to 32 °C, and at room temperature (control, 25 °C). Amy maintained consistent flow rates across all conditions. The CADD-Solis also exhibited consistent flow rates, with minor yet statistically significant changes upon epidural catheter placement (- 5.0%, P = 0.005) and motion conditions (4.2%, P = 0.015). The Balloonjector and Rakurakufuser exhibited flow rate variations over time, and temperature increases significan
