Answer 1

Others already talked about oxygen, but the other and more important part of CPR is that you’re helping sort of jump start the lungs by getting them to expand and contract, which can help with blockages and other stuff, but always remember to check the airway first.

Additionally the mouth to mouth part of cpr is falling slightly out of favor as chest compressions do all the heavy lifting.
