A networked symbiotic assistive user system is presented. The architecture of the system allows devices worn by medical first responders such as medics or EMTs, to connect wirelessly to devices coupled to patients, devices worn by other medical first responders and adapter devices (such as those that may be located in air and/or land evacuation vehicles) that connect to a legacy infrastructure. Using a variety of medical first responder oriented communications protocols and applications, the devices can exchange information with all of the other devices in a manner that assists the medical first responders as well as personnel associated with the legacy infrastructure (e.g., tactical command operations personnel, first aid station personnel, or other medical facilities personnel).
