Another thought for details on the card could be a section for medical conditions, eg diabetic, pacemaker, hearing or speech impairment or anything else that might be relevant. This not only helps the medical responders but may also allow a bystander to assist better and be able to give the 000 call centre more information when calling. I know people with some conditions wear medialert bracelets etc and are usually well prepared to deal with there conditions but there might be that one time when that info is needed.
