Completely disagree with this, basic awareness and training in the use of an AED is important. I don't disagree that they are not easy to use to someone who has been trained in medical emergencies as they would have a basic grounding. However like most things people need to firstly recognise how to identify and access an AED and secondly feel confident in using one correctly under pressure.
If you put one of these on each floor of a busy office, staged a cardiac arrest, most people wouldn't utilise it unless they were trained.
I find it incredulous that you would suggest otherwise.
