Having watched this thread, I have come to a conclusion.....


Got a pre-existing medical condition that EMS might need to know about? Stop trying to re-invent the wheel and get the Med-Alert jewelry.

Keep a paper ID information card in one's wallet with all the info the fine EMS folks have listed here.

Maybe keep a USB drive with the entire medical history on your person, but DO NOT expect someone to plug it into the laptop on the bus in the field.

If you don't want to comply with those simple rules, hope your EMS crew is omniscient or deal with the consequences to you own health.
