airborne6684 unless you are a PARAMEDIC the main advice you can expect to get on this forum is ridicule! No other medic quite makes the grade no matter how good or extensive your training!
Don't be silly!
I am not a Para, yet still I can see the ridiculousness of the question.
To answer it seriously...
Your medical kit needs to suit your skills and the situation, there are some things you can travel with and some you have to get in location. There is not point carrying gear "in case an HCP turns up", because they either will not or they will have their own kit.
Add to this that there are really two definitions of First Aid Kit:
1) The box of plasters you find in every workplace or boot of a car.
2) An actual life saving collection of well chosen gear that the owner knows how to use.
Option number two is usually a very simple set of stuff, things like CATs, Celox, Aspirin, Iripods, big dressings etc.
FPOS is a First Aid Qualification, it is designed for people who are holding on for 10-60 mins until a professional can get there. The kit carried by ambulance trust community responders (who the course was written for) will carry the stuff mentioned above, plus a defib and oxygen.
So no, the ridicule is not because the OP is not a Para, but because the question is not a sensible one.
