A device that can facilitate monitoring a wearer of the device and alerting emergency personnel of an emergent event can comprise a first sensor configured to generate elevation data that represents an elevation of the device, a second sensor configured to collect vital sign data of the wearer, and a third sensor configured to generate a geographic position of the device. The device also includes a processor configured to determine an elevation of a floor, and a floor location of the device. The processor is also configured to detect an emergent event affecting the wearer based on the first or second sensor. The device also includes a transmitter configured to transmit an initial alert in response to detecting an emergent event. The transmitter also configured to transmit a secondary alert in response to generating the geographic position and determining the floor location of the device within a pre-set time period of the emergent event. |
