Systems and methods of determining locations of medical devices relative to wearable devices

A system for directing emergency personnel to a medical device, the system comprising:

• one or more servers having a location database that stores geographic location for a plurality of medical devices;
• a wearable device separate from the plurality of medical devices, the wearable device comprising one or more antennas and one or more processors configured to:
• receive, via the one or more antennas, location information from at least one location information source external to the wearable device;
• estimate a location of the wearable device based on the received location information;
• transmit, via the one or more antennas, the estimated location of the wearable device to the one or more servers;
• receive, via the one or more antennas, information descriptive of a location of at least one of the plurality of medical devices;
• determine a path between the location of the wearable device and the location of the at least one medical device;
• and
• provide one or more of audible and visual information descriptive of the path.

A method for directing emergency personnel to a medical device, the method comprising:

• receiving, at a wearable device, a signal communicating location information from at least one location information source of a plurality of location information sources;
• estimating a location of the wearable device based on the received location information;
• transmitting the estimated location from the wearable device to at least one server;
• receiving, at the wearable device, information descriptive of a location of the medical device, wherein the medical device is separate from the wearable device;
• determine a path between the estimated location of the wearable device and the location of the medical device;
• and
• provide one or more of audible and visual information descriptive of the path.
