Wonderin star, you have mentioned something that I have enquired about before.
I served for a few years as a medic in the RAuxAF, the training I had there prepared me for situations that may evolve whilst we were "out and about".
Since leaving the RAuxAF, I have tried to get a qualification that is recognised in civvi street (my RAF training is not
), however, the closest qualification I have found is that of "Advanced First aider", these courses are run by the St Johns and as far as I know are reasonably cheap. The knowledge gained should suffice for what you are asking about, and the beuty is the courses are usually run locally and over a fairly extended period, depending on how much you want out of the course.
Good luck mate.
