What could cause an alarm in an electronic infusion device (EID) after changing the IV fluid bag?

When an electronic infusion device (EID) triggers an alarm after changing the IV fluid bag, one likely reason is that the roller clamp is set to the "off" position. In this scenario, the roller clamp controls the flow of fluid from the IV bag into the patient's intravenous line. If the clamp is closed, it prevents any fluid from passing through, which the EID detects and will consequently alert the user with an alarm indicating that the infusion is obstructed or has stopped.

This situation highlights the importance of ensuring that all components of the IV setup, including the roller clamp, are correctly configured before starting or resuming an infusion. The alarm serves as a safety feature to prompt healthcare personnel to check for potential issues that may interrupt therapy, ensuring patient safety and the effectiveness of the infusion process.
