Abstract
Unexpected changes in the volume of therapeutic fluid in the reservoir of a fluid delivery device are detected based on changes in the pressure of the reservoir measured over a period of time by a pressure sensor. Additionally, an ambulatory reservoir fluid volume gauge is provided to indicate an actual volume of therapeutic fluid in a fluid delivery device reservoir. The actual volume of therapeutic fluid in the reservoir indicated by the ambulatory reservoir fluid volume gauge is determined based on changes in the pressure in the reservoir measured over a period of time by a pressure sensor.
