ACT is an innovative emergency response application designed to Aid, Care and Treat an injured party in a medical emergency situation, to enhance and radically improve existing emergency response processes and, ultimately, to save lives. The development of ACT is driven by a commitment to optimise the traditional process in order to improve patient outcomes in critical situations. We have created a technological aid which facilitates the direct and instantaneous transmission of an end-user's personal and medical information, as well as their geolocation coordinates, to responding service providers in the event of an emergency. It also equips end-users with the tools and guidance to take prompt, potentially life-saving actions whilst awaiting professional medical intervention.
