Abstract
A medication injection device includes a barrel and a plunger disposed to dispense a fluid from the barrel. A dosage tracking system is coupled to output data indicative of the fluid dispensed. A controller is disposed within the medication injection device and coupled to receive the data from the dosage tracking system. The controller includes logic that when executed by the controller causes the controller to perform operations including determining, based on the data, whether an air shot event occurred while dispensing the fluid.
