That’s the advice we have to give when using the American 999 triage system called AMPDS. Lots of ambulance trusts still use it but down here in the South West we now use a much more appropriate triage system called Pathways.
I believe the decision on laying them on their back was based on a few reasons; easier for Joe Public to do, easier to monitor their airway and finally, if the patient is to stop breathing then they are already in the best position.
Both Paramedics and control staff were always questioning this practice.
@deviant – You are right, it’s an American system which is always working around their blame and compensation culture…
