Embodiments described herein relate to a self-contained breathing apparatus, and more particularly, to a self-contained breathing apparatus that uses extraction and exchange of oxygen and carbon dioxide between a perfluorocarbon and water in which the apparatus is immersed. Embodiments include a water-to-perfluorocarbon exchange chamber; an air-to-perfluorocarbon exchange chamber; and a circulation pump, where the circulation pump is configured to circulate perfluorocarbon between the water-to-perfluorocarbon exchange chamber and the air-to-perfluorocarbon exchange chamber, where the perfluorocarbon becomes oxygen rich in response to passing through the water-to-perfluorocarbon exchange chamber, and where the perfluorocarbon becomes oxygen depleted in response to passing through the air-to-perfluorocarbon exchange chamber.
