Sean what you have said is quite true (Well Doc as well
) Epi pens are a bit of a legal liability if used improperly and if misdiagnosed an Epi Pen can worsen a problem rather than make it better.
I think for airsoft purposes Doc Hollywoods kit is a bit on the overkill side but for practicall military purposes it's the bare minimum.
Here is what I have in my AIRSOFT IFAK.
Bandaids, all shapes and sizes, about 30 total
Alcohol prep whipes, 15
1 pair of latex free gloves
2 packets of IB profin
2 packets of Tylenol
2 Packets of Immodium AD
2 packets of benadril
1 Large foldable gauss pad
2 packets of Cortaid antiich/burn ointment
Gauss Tape
For AZ it might not be a bad idea to get a very very basic antivenom kit, however I think most venom kits are specific to a certain species? (not sure!)
Important to remember is that knowing what the injury is is more important then knowing how to fix all sorts of injuries. If you cant properly diagnose an injury then you need to find someone who does. I recently helped a man who broke his ankle out of a ravine. My First aid skills went into overdrive because it was not directly apprent that he broke his ankle, however the fact he could not move his ankle very well without serious pain ment that we would have to carry him out with all pressure off. Luckily we had a person there who was a medic in the military who properly diagnosed the issue to it. After a doctors visit we found out he had a spiral fracture on one of his bones in his leg and a seriously sprained ankle.
So having a First aid kit is nice, but knowing how to treat stuff is more important and knowing how to diagnose correctly an injury is more important than that, so I encourage you to go and get and learn first aid skills as well as CPR and some of the first responder skills as they are all important. I know carrying a FAK doesnt seem like it should carry that much weight but it is very reasurring for people who play with me to know they have a CPR/First responder on scene to help fix people up. So far the ankle is the worst problem i've seen in an airsoft game followed by minor puncture wounds and cuts and abbrasions, all of which are easily fixed with a good alcohol whipe, a little bit of gauss and a bandaid wrapped in with gauss tape.
Cheers, carry on.
PS. Thats a nice First Aid kit Doc.
EDIT: Forgot something, make a simple card with your name and the easiest method of contacting you incase any doctor needs to know what all you have done in terms of first aid for the more serious events. Also keep track of all first aid treatments in a card format so that when paramedics arrive you can give them a very quick yet informative "debreif" (if you will) on what you have done to help prevent the loss of life. Stuff like that can make the difference.
