Abstract: A wearable drug delivery device for monitoring unintended over-delivery and/or under-delivery of a stored liquid drug are provided. An absolute pressure sensor can be positioned within the fluid path of the drug delivery device. The absolute pressor sensor can detect both ambient pressure (e.g., absolute or atmospheric pressure) and relative pressure (gage or pumping pressure). Based on the detected pressures, the effects of external ambient pressure on air with the fluid path can be determined during both intended drug delivery events and unintended drug delivery events. In turn, under-delivery and/or over-delivery of the liquid drug can be determined. Based on the severity of the determined under-delivery or over-delivery of the liquid drug, alarms indicating different urgencies can be provided to the user.
