The important message we need to get across to people is to not be afraid to intervene. The person cannot be worse off after an intervention than they were before. It's better to administer bad intervention than not to intervene at all.
That is the message we like to drive home when we provide training at schools or other places. We tell participants not to be afraid to intervene, that they will not be sued if they do something wrong, and that the person will die if nothing is done. We tell them that the person cannot be worse off after an intervention than before.
I think that the more we get this message out, the better our chances for resuscitation.
