Ah then Bobby the ranter - I didn't say it was a JRCalc protocol or even a national one but maybe in your ivory tower you haven't heard of the National Infarct Angioplasty Project.
The aim is to get MI patients into a hospital with a cardiac catheter lab for angioplasty within 150 mins from the call for help. Our hospital of choice for this is Royal Devon and Exeter, bypassing NDDH if the patient meets the criteria.
Given the distance from said hospital that most of Devon is, a scoop and run is the probable weapon of choice.
As already stated in this thread doing CPR in the back of a smaller (but much more modern and capable) helicopter is hard work! Paramedic crews agree that better to do the 20 mins on scene. If you get a result take the patient to hospital for definitive aftercare. If no result.......well!
so the tail is wagging the dog here - if the helicopter was bigger, you could do the 20 mins CPR on the way to hospital but you can't, so you don't and if the patient dies in a field.....well!!
As for the resus protocols, not only am I aware of them but have done them for real which I suspect you might not have - the advantage of a bigger helo with 2 pilots.
Thud - I think the medical standards in SAR aircraft have significantly risen since you and many other ex mil AA pilots did SAR.
Oh and while we are being so precious, exactly who goes out to do this stuff in the dark in UK?
