Closed-circuit rebreathers use a different approach in supplying life support to the diver. At the heart of the system are the diver's lungs, which move breathing gas through a closed, circulating loop. Every exhaled breath, of course, contains carbon dioxide and a diminished level of oxygen, so the rebreather's primary tasks are to remove the carbon dioxide and …
