Hey Tom, obviously i'm not a para or even a tech, but i'd have to agree with the previous commenters you were a little screwed. Not sure what the of state of paras there are, but could you have stayed, doing the cpr dance while a para could get on the scene and maybe stabilized the guy a little? Still, like someone mentioned - if a patient won't look after themselves, there is little you can do - diabetes especially, where your body can be shutting down and you don't entirely know about it... Definitely consider the para course - i'm sure you have the skills, so why not use them ? :)
