The healthcare question to be addressed by this project is whether mobile video telemetry might be used to aid paramedics in the diagnosis, resuscitation and triage of patients.  The engineering challenge is to develop technology to fulfil this role.  The specific scenario is one that links ambulance paramedics to a base Emergency Department by a digital wireless link providing video, voice and data for communication between paramedics in the field and senior emergency physicians in hospital.  In this way medical input to the immediate management of an emergency would be possible.  The system is a mobile emergency videotelemetry unit in which a ruggedized PC is linked to a control centre by a digital cellular radio network.  The system will be used in randomised clinical trial by motorcycle paramedics equippd with both video and still digital cameras.  The cameras send pictures to the mobile PC via a short range wireless local area network, which relays multiplexed real time video and slow scan high resolution images to clinicians in the Emergency Department, who are also in constant voice contact with the  paramedic.
