My company have just fit them all over the offices. Unfortunately they've made it unnecessarily beurocratic and told everyone they're not allowed to use them without going on a training course. Then guy who campaigned for them to be fit is not best pleased about this.
To be fair, there's nothing wrong with a bit of training. However you're encouraged to attempt to use one without any training, should someone be showing signs of cardiac arrest. The resuscitation council is very clear on this.
"While it is highly desirable that those who may be called upon to use an AED should be trained in their use, and keep their skills up to date, circumstances can dictate that no trained operator (or a trained operator whose certificate of training has expired) is present at the site of an emergency. Under these circumstances no inhibitions should be placed on any person willing to use an AED".
I think Burnsys comment is slightly naive, and somewhat worrying. Training in medical emergencies and the correct use of an AED should not be frowned upon.
