AED on O2 administration training is part of the PADI EFR class required for all rescue divers and required for all professionals, renewed every 2 years. Most dive boats have them, we have one at open water training weekends, there is one at my dive center, and there is even one in the lobby of my church. At open water weekends we review briefly all EFR procedures with all dive pros and DM candidates. We also survey parents and friends who are along and not diving, and make note of any trained medical people. Good things to have, and while they can be used with little or no training, training is appropriate and desirable, particularly as it comes to efficiency in set up and use, which can be a life saving issue.
