Abstract

A system is provided for tracking an individual, engaged in extreme physical activity, physiological status and detecting and predicting negative physiological events. A monitoring system is provided that includes a plurality of sensors. Each sensor has a sensor output, and a combination of the sensor outputs is used to determine distress of the monitored individual engaged in extreme physical activity. A wireless communication device is coupled to the plurality of sensors and transfers data directly or indirectly from the plurality of sensors to a remote monitoring system. A remote monitoring system is coupled to the wireless communication device and configured to receive the processed data.
