When you inhale normal air, the air that you breathe in is about 70% nitrogen, 20% oxygen, and 1% "other" gasses. Your lungs exchange some of the oxygen in the air for carbon dioxide and water vapor, but your exhaled breath generally still contains about 16% oxygen.

THat's why "mouth to mouth" CPR and artificial respiration works.
