Effect of infusion line connection and infusion line characteristics on start‐up fluid delivery from syringe infusion pumps used for microinfusion

Abstract

Background: Connecting an infusion line to a closed stopcock results in pressurization of fluid within the syringe infusion pump assembly leading to flow irregularities when opening the stopcock and activating the pump. Aims: It was the purpose of this study to assess the extent of pressurization under different conditions and its impact on start‐up fluid delivery. Methods: Intraluminal pressures and start‐up fluid delivery at 1 mL/h flow rate were assessed with connection of the infusion line 1 min (delayed connection) or immediately Show more
