That said, I realize the likelyhood of me ever needing any of these items is extremely remote (and clearly beyond my CPR/AED/WFASRM certification) although I can think of very few things that would be worse than watching helplessly as a close friend or loved one suffocates due to a traumatic injury.
something tells me you are older than the asker (13yrs). and that you have more experience than him too (CPR/AED/WFASRM certification).
he's asking for his
boy scout troop-mates. and who's going to train them?
An cricothyrotomy is clearly the most invasive procedure listed above, yet there are numerous reported instances of cricothyroidotomies having been performed successfully by untrained individuals using scissors, hunting knives, razor blades, broken glass, and even the jagged edge of a lid from a tin can.
there's been discussion here that boy scout leaders have a hard time with the scouts carrying knives, let alone a crico set.
An additional case for having some or all of these items in a FAK would be the instance where a trained medical professional (doctor, nurse, or EMT) is on-site and available to help someone, but does not actually have the necessary items available.
why not give 'em iv setups, epi and bicarb amps too?
ok, so maybe that's overboard, but IMHO you have to draw the line somewhere. and IMHO airways is a good place to start. when age-appropriate, ok.
