Re: 1st Aid at Sea & Important Like Items to Carry
I'd go with a SAM splint (the longest one that comes rolled up). Pretty cheap ($10-15), easy to use, compact, and lots and lots of splinting uses.
Dunno about the BVM (ambu bag). That's a bulky (and more expensive $20) item that could be remedied with a simple pocket mask ($5). Plus the person would have to be trained for how and when to use a BVM. The pocket mask is easier to use and works fine. Current AHA guidelines support ventilationless chest compressions ("compression-only CPR") with evidence of high efficacy anyway for out-of-hospital cardiac arrest management. Isolated respiratory arrest without cardiac compromise is rare and most likely exacerbation of a pre-existing medical condition such as asthma or COPD. In that case, it takes us back to crew-specific Rx meds and a face mask.
