How does an underwater rebreather work?

Basically, when you breathe in air from regular SCUBA gear, only about a fourth of the oxygen you breathe gets inhaled. So in a rebreather, the rest of the air and the carbon dioxide goes through a scrubbing system of calcium and sodium hydroxide. Then it goes through the rest of the loop and you breathe it in again.
