I knew that a mass casualty lightning strike is the one exception to the rule that, in an MCI, no breathing + no pulse = lowest priority; however, I didn't know the reasoning behind it (other than that pulseless lightning strike victims stand a much better chance of survival with CPR than trauma victims).

The explanation given - that anyone who is still breathing following a lightning strike is likely to keep doing so without assistance - makes sense, and fits in with what I've been taught (and been teaching).

Thanks.
