In Vivo Study of Flow‐Rate Accuracy of the MedStream Programmable Infusion System

Objective:  Flow‐rate accuracy and precision are important parameters to optimizing the efficacy of programmable intrathecal (IT) infusion pump delivery systems. Current programmable IT pumps are accurate within ±14.5% of their programed infusion rate when assessed under ideal environmental conditions and specific flow‐rate settings in vitro. We assessed the flow‐rate accuracy of a novel programmable pump system across its entire flow‐rate range under typical conditions in sheep (in vivo) and nominal conditions in vitro.
