The article is about internal defibrillators. External ones are still the same as (good grief) 35 years ago (well maybe down from 300J to 200J). The only change I've noticed is moving from a gel for the pads to a gel pad (which feel like a frog, chuck one in your partners bed and let them find it!) which reduced the possibility of burning and odd smells in your ambulance. Fortunately my sense of smell wasn't great and often had a partner who smoked (and was allowed to in the olden days) in the ambulance to dull it. You kids don't know how it was having to actually manually read the trace instead of all this new-fangled automation that guides you through it.
