ELI5 CPR - what is Michael Jackson’s association to CPR?

If we breathe out carbon dioxide, why does CPR work? Why does modern CPR training de-emphasize rescue breaths? CPR manuals talk about doing 100-120 chest compressions per minute - why so much faster than the average pulse of around 60-80? What does Michael Jackson have to do with CPR?
