Abstract

A defibrillator is disclosed for communication with a transmitter associated with a location. The defibrillator is configured to generate an electronic signature for determining a position of the defibrillator within the location. The electronic signature includes electronic data correlating the position of the defibrillator to the transmitter. The electronic data may include GPS data. The defibrillator is configured to generate the electronic signature during a first and a second window of time to define a first and a second electronic signature. A differential between the first and the second electronic signatures corresponds to a positional state of the defibrillator, indicating movement within or between two locations. In a disclosed system, the first electronic signature is stored in a database and a server is configured to generate the differential and to communicate the positional state of the defibrillator to a stakeholder. Methods of use are also disclosed.
