E-Vanguard for Emergency - a wireless system for rescue and healthcare

E-Vanguard for Emergency, called hereafter the EVE, provides a system that helps the rescue and first-aid work in the present rescue operation. The EVE consists of rescuers equipped with wearable PDAs, medics with laptops plus GPS, a rescue command center controlled by the leaders of the rescue and medical teams, and a monitor subsystem including physical sensors, such as an oximeter and an electro-cardiograph, provided with wireless transmission for the injured. Each part communicates with all the others using Bluetooth. The EVE improves the rescue work by monitoring rescuers´ physical conditions and the environment temperature to give an early warning. It also helps first-aid work by providing medics with real-time information about the injured and having in band the medics´ positions for efficient allocation of medical resources. In addition, the system collects instant medical information of the injured through sensors and transmits the data to the nearby medics or rescuers, which are further relayed back to the rescue command post. The unique feature of Bluetooth is exploited by the EVE system to construct a Bluetooth relay network, a Scatternet.
