The other person that was advocating 8 mins was Dr Carney of East Anglia Fame who was also heading up the ATLS,noting in his training sessions to us all (thats when is back was not too bad and he was not having the figures adjusted to reach the target times) that the brain starts to loss all the oxygen so it was imperative to get on scene in 8 mins But we have known that for donkeys years so why all the fuss now
