If the IV pump signals an occlusion, which could be a possible cause?

When the IV pump signals an occlusion, one possible cause is kinked tubing. Kinking in the IV tubing can create a blockage that interferes with the flow of fluid through the system. This blockage triggers the alarm on the IV pump, as it detects increased pressure or a lack of flow. Checking for kinks in the tubing is a common troubleshooting step that should be taken immediately to resolve the occlusion signal.

While low battery, an empty IV bag, or incompatible IV solutions may affect the IV pump's function in other ways, they do not directly relate to the occlusion signal. Low battery might result in the pump shutting down or alarm for power issues, while an empty IV bag would stop fluid delivery but not trigger an occlusion alarm. Incompatible solutions might cause complications once mixed, but they are unlikely to cause an immediate occlusion signal related to flow. Thus, kinked tubing stands out as the most likely and direct cause for the occlusion alarm.
