Do a person use all the oxygen they breathe in?
No. Normal air is about 20% oxygen, 79% nitrogen, and 1% "other gasses". That's what you inhale when you breathe. Your exhalations - what you breathe OUT - is about 79% nitrogen, 16% oxygen, 2% carbon dioxide, 2% water vapor, and that 1% of "other" gasses. When you perform artificial respiration, you are breathing OUT, directly INTO the victim's mouth. Your exhalation of 16% oxygen is plenty for him to survive on.

What are the lungs like?
The lungs act a bit like baloons. When you breathe in they will inflate, when you breathe out they will deflate.
