Yeah, it definitely takes a village, or a commitment to ALS and AEDs, or the whole chain of efforts in the Medic One documents. Yet for all the AEDs King County is a pretty large place, so I reckon a similar effort in Alabama or LA should yield similar results. The effort is worthwhile I think - if you start CPR knowing that another responder will be running for an AED, and ALS or BLS are coming within 4-8 minutes on a good day, and you have a better than even shot at resuscitating this person and their walking out of the hospital alive, you change your attitude and no longer think of the 5 or 10 percent long shots to survival. That's especially important for saving family members lives, when I don't want the long odds in the back of my mind.
