How does CPR work if we exhale co2?

When you breathe out, your diaphragm relaxes and curves back up as your lungs push the air out.

Why do I Hold my Breath when I Exhale?
A cycle is set in motion and you keep inhaling for more oxygen, but can’t get enough because the lungs have not been properly emptied. This habit can lead to shallow breathing and holding your breath. However, when you exhale completely, your body is designed to take a “reflex” inhale.
What happens to the air in your lungs when you inhale?
When you exhale air from your lungs, some of it stays in your trachea. When you inhale, this “already processed” air gets back into your lungs again, and only then, the air from the outside gets in and becomes mixed with “tracheal” air. You never have air in your lungs that has as high oxygen content as the room air.
What happens when you don’t Exhale properly?
Because most people are busy taking an in-breath, they do not pay much attention to the exhale process. Without exhaling completely, excess carbon dioxide — a known stressor in your nervous system — may remain in your lungs. The system detects that there is too much carbon dioxide and not enough oxygen.
