What is the most common type of alarm that tells if an insulin pump is functioning improperly?

The most common type of alarm that indicates whether an insulin pump is functioning improperly is the delivery alert. This alarm is specifically designed to notify the user if there is an issue with the insulin delivery, such as an occlusion in the tubing or an empty insulin reservoir. These types of alerts are crucial for maintaining proper insulin delivery, as any interruption can have immediate effects on blood glucose levels and overall diabetes management.

In the context of insulin pumps, other alarms can also provide important information, but they do not directly relate to the functionality of insulin delivery. For instance, a battery alert indicates that the power source needs attention, while a temperature alarm relates to the operational environment of the pump. An insulin reservoir alert would inform the user about the insulin supply but does not specifically indicate a malfunction in the pump's delivery system. Therefore, the delivery alert is the most relevant when assessing the functionality of the insulin pump.
