I should redo my CPR then. Learned two on the front in high school in NJ. But also to read the instructions though I'm sure when seconds count you don't.
Modern AEDs have voice guidance telling the person what to do. So you can follow the instructions as you do it.
Also, you should call the emergency number in your region and (at least in Australia) they'll transfer you to someone who can coach you through using the defib and performing CPR until professional help arrives.
Don't let that stop anyone from getting their CPR up to date though. The more experience you have the better equipped you'll be if you need to use it
I see AEDs at work. If I have a heart attack, I have no confidence in my team being able to use it. I've seen how they handle requirements and documentation in stories.
