Whether it is five or two cycles of CPR before AED, unless you are resuscitating someone who doesn't need it or it was transient such as a borderline electrocution, anyone without cardiac activity is going to need AED and prompt ALS transport to survive. Period.
I'm with you there, Crofty, but like the next message asks, I think the word prompt goes in front of AED. I would see ALS as consolidating these rescues, but not initiating them.
Many areas they could be posted would experience pilferage. We see many AED's sited behind the manager's desk in a l,ocked office, used as a doorstop, or messed with so the electrodes are breached and/or batteries discharged. They never learn, they never drill or train unless we sweet talk them or someone enforces the regs.
A big reason why I think one PAD in the lobby with proper security cleans up most of the issues you cite.
I think maybe a plug-in AED for use in places like restaurants, nursing homes, assisted living facilities, health clubs etc. would be a good and cheaper product.
That's a very good idea. The battery schemes on AED have to be a significant part of their cost to build and maintain.
