I hope you will be working when I need an AED. But you guys are pros, following an established routine in a familiar environment. Some hiker, having never encountered a snakebite before, is bitten out of the blue. i think it will take a while to even realize exactly what is going on. Then....Dp you have that snakebite thingy? I think so... Well get it! Uhhh...OK, how does it work? Where are you bitten? All accompanied by various alarms and excursions.... And you are probably wondering where Mr Snake is, and trying to avoid him......

It is an interesting question. How long does it actually take before the victim, out in the real world, gets any kind of treatment?
