I don't understand how CPR works we breathe in oxygen and we exhale CO2 so how come during CPR when we breathe into the person we are exhaling CO2 into there body insted of oxygen?
Atmospheric air has about 20.5% oxygen and our lungs only extract about 4.5% oxygen, so the air we exhale has about 16% oxygen, 4.5% CO2. The air we breathe into the victim then has 16% oxygen for their lungs to extract oxygen from.
