I spent 7 months on an IRV(thats what we call them round our way), they were introduced as a cat A beater, they seemed to work quite well, we had two teams of chaps, who took pride in what they were doing, we were sent out as an initial response and asked for backup if needed, an Ambulance was only sent if it was a cat A call as well i.e. chest pains. After seven months i was knackered, found a new friend who still speaks to now, strangely only at night when its quiet ive never seen him only heard him!!! The thing is if someone calls for an Ambulance then they generally want an Ambulance, the amount of times i turned up at jobs and the relatives got quite abusive 'cos they wanted an Ambulance, no amount of explaining the"new" system was going to change their minds. It'll all go full circle again in the end, we'll have vehicles with two trolleys on before much longer, like the good old days, before trusts were invented.......................geeze i sound old!!!
