We breathe in oxygen and breathe carbon dioxide. So if you breathe into a person's mouth hoping to revive them, aren't you breathing CO2 into them, which is of no help for them?

The human body is not 100% efficient in extracting oxygen from each breath inhaled.
Also, there is a reason why you breath into a bag when hyperventilating.

[quote] Our body only uses around 5% of the Oxygen that we breath in. As a result, our exhaled breath contains approximately 16% Oxygen. This 16% is more than enough to supply through rescue breathing.

I always wondered about this. Apparently, the action helps get the heart pumping so it will produce oxygen on its own?
