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 at least one server; receive, via the one or more antennas, information descriptive of a location of at least one medical device separate from the wearable device; 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. ### Claim 2 (depends on 1) The wearable device of claim 1, wherein the at least one location information source comprises at least one of a GPS source, cellular network source, satellite, WLAN access point, a Bluetooth source, and an RFID tag. ### Claim 3 (depends on 1) The wearable device of claim 1, wherein the location information comprises an identifier for the at least one location information source. ### Claim 4 (depends on 3) The wearable device of claim 3, wherein the one or more processors are further configured to execute the computer-executable instructions to transmit a strength of a signal received from the at least one location information source to the at least one server. ### Claim 5 (depends on 1) The wearable device of claim 1, wherein the wearable device comprises at least one of an earpiece, a pair of glasses, and a watch. ### Claim 6 (depends on 1) The wearable device of claim 1, wherein the wearable device further comprises a display, and the one or more processors are configured to provide the information descriptive of the path by displaying directions regarding the path via the display. ### Claim 7 (depends on 1) The wearable device of claim 1, wherein the one or more processors are configured to transmit, via the one or more antennas, a notification to the medical device to issue an audible sound so as to assist the emergency personnel to locate the medical device when the wearable device is within a threshold distance of the medical device. ### Claim 8 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. ### Claim 9 (depends on 8) The system of claim 8, wherein: the location information received from the at least one location information source external to the wearable device comprises an identifier for the at least one location information source; and the location of the wearable device received from the at least one server is derived at least in part from the geographic location stored in the location database for the location information source corresponding to the identifier. ### Claim 10 (depends on 9) The system of claim 9, wherein: the one or more processors of the wearable device are further configured to transmit to the one or more servers a strength of a signal received from the at least one location information source; and the location of the wearable device received from the at least one server is derived at least in part based on the strength of the received signal. ### Claim 11 (depends on 8) The system of claim 8, wherein the at least one location information source comprises at least one of a GPS source, cellular network source, satellite, WLAN access point, a Bluetooth source, and an RFID tag. ### Claim 12 (depends on 8) The system of claim 8, wherein the wearable device comprises at least one of an earpiece, a pair of glasses, and a watch. ### Claim 13 (depends on 8) The system of claim 8, wherein the wearable device further comprises a display, and the one or more processors are configured to provide the information descriptive of the path by displaying directions regarding the path via the display. ### Claim 14 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;
