Everyone should take a cpr class. It's a skill you'll wish you had when you need it.
Ive had to do it three times now, one survived two did not. Still feel some guilt for not being able to help them. Can't imagine how I'd feel had I not being able to try.
Nothing screams poor craftsmanship like wrinkles in your duct tape
Don't. Nothing to feel guilty about. You tried. Over the course of almost 30 years on the FD I've done CPR on hundreds of people and only seen two that ever made it out of the ER.
