There is no such change in the American Heart Association guidelines for Emergency Cardiac Care. A pulseless person gets CPR unless they are a DNR or OBVIOUSLY dead (rigor, pooling blood, decapitation, massive trauma)
Stating such a fallacy as fact is dangerous.. because other people just.. might... believe you..
Statistics for CPR saves are already dismal, because in most cases the person is dying, not suffering from an easily remedied transient event...There's no need to put lipstick on the pig..
