To answer this question we need to look at some numbers:
Air in the atmosphere that we breath in contains around 21% Oxygen. If you read different sources they will all give you slightly different figures however the figure is around 21%.
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.
