If my heart stops I hope bystander Johnny Hero at least tries while 911 is enroute.

I know if your heart stops in front of me and Mrs we will be all over you instantly,not making a judgment call on should we or shouldnt we.

Ive made that call after a code is finished in retrospect,but never to not start short of rigor mortis or do not resuscitate order if someone collapses.

OK,once at an accident scene when the guys brain was all over the road.It was pretty clear he wasnt going to live without a brain,or be revived.
