If we breathe out carbon dioxide why does CPR work?
In: Biology
A real ELI5 explanation:
You push on the chest fast, about 100 times every minute, to keep the blood moving through the body because the heart isn’t working. Even if you can’t give any extra oxygen, CPR still helps because any oxygen is better than none. If the brain doesn’t get oxygen it dies piece by piece.
