Please Remove the Lamprey

I was at a party the other night. Eventually, I found myself on the sofa, chatting with a rather inebriated fellow who was eating very large handfuls of trail mix from a bowl on the coffee table.

It occurred to me, as this nameless individual (he probably had a name, I just never learned it) wolfed down said trail mix that I might have to give him the Heimlich Maneuver. In a worst case scenario, I might even have to give him an emergency tracheotomy.

As we chatted, three things occurred to me:
1) I might need a really sharp knife
2) My warrior needs a butt-load of Fel-Iron
3) How would I know when I needed to perform the tracheotomy?

I mean, if this guy is choking to death, how will I know when to actually perform said tracheotomy? And how long is it going to take to farm all that Fel Iron?

I then had a brilliant idea: emergency-specific flash cards.

This would be a set of cards with specific emergency messages pre-printed upon them, to be used in case you cannot adequately convey what is needed. For example: I am choking to death. Please perform an emergency tracheotomy.

Other, useful cards might include:
Please remove the lamprey from my buttocks
The knife in my head is not fake
Please collect my limb(s) for potential reattachment
I am on fire
I am currently falling to my death. Please provide a parachute, trampoline or other gravity-defying device
Please distract the lion eating my leg. If possible, recover my leg.

Granted, to be truly prepared would require a large assortment of cards, making it difficult to find the correct one. Therefore, the first card in the pack would read: I am having an emergency moment. Please be patient while I locate the correct card to adequately convey my situation.

Cheers,
