If we breathe out carbon dioxide why does CPR work?

FYI the most important part of CPR are the compressions to keep blood flowing through your body, not the rescue breaths. If you have to choose either or, choose compressions every time.

Giving 2 breaths per ~30 compressions is optimal, but not if the person was choking or has an open mouth wound.
