Liquid Breathing and Artificial Gills
Liquid breathing is a type of respiration in which a human breathes an oxygen-rich liquid such as a perjluorocarbon (PFC).1 PFCs were synthesized during the development of the atomic bomb (the Manhattan Project) when they were given the codename “Joe’s stuff”. PFCs are organic compounds in which all hydrogen atoms have been replaced by halogens, usually fluoride. In medical applications, the compounds are being evaluated as contrast agents for computerized tomography (CT) and magnetic resonance imaging (MRI), as sensitizing agents during radiotherapy, and as possible oxygen-carrying agents. Because PFCs are stable, inert compounds, they do not react with living tissues, which makes them an ideal candidate for all sorts of medical applications. Currently, the primary application of liquid breathing is the medical treatment of lung problems in babies born prematurely [1, 2].
