Abstract: Systems and methods for simultaneously tracking physical conditions of multiple people during an event are disclosed. The system comprises at least one vital sign data collection device, a central processing unit compiling the collected vital sign data, and software executing on the central processing unit. Wherein the software analyzes the data for each person, determines if the vital signs of each person are above a threshold, recommends rehabilitation for each person having vital signs above the threshold, determines when each person undergoing rehabilitation has been rehabilitated, recommends returning rehabilitated persons to the field, compiles an analysis of the multiple people tracked during the event, and outputs a summary of the vital sign data for the event.
