What observation indicates a slowed infusion rate in an IV line?

A cooled and swollen IV site is a clear indicator of a slowed infusion rate. This observation suggests that there may be an issue with the flow of IV fluids, meaning that they are not being delivered efficiently into the patient's bloodstream. The swelling (potentially indicating infiltration or fluid accumulation in the surrounding tissue) combined with the cooler temperature can signal that the IV line may not be functioning correctly, possibly due to kinking, obstruction, or improper placement.

Other scenarios, such as an empty IV bag, would indicate that the infusion has completely stopped rather than simply slowed. A partially full drip chamber does not, by itself, provide sufficient information, as it might still allow the infusion to proceed at a reduced rate but does not directly point to obstruction or infiltration. By identifying a cool and swollen IV site, healthcare providers can take the necessary steps to assess and address the IV line's functioning to ensure proper fluid administration.
