Liquid breathing

Computer models of three perfluorochemical molecules used for biomedical applications and for liquid ventilation studies: a) FC-75, b) perflubron, and c) perfluorodecalin.

Computer-generated model of perflubron and gentamicin molecules in liquid suspension for pulmonary administration

Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid (such as a perfluorocarbon), rather than breathing air.

Perfluorochemical (perfluorocarbon) molecules have very different structures that impart different physical properties such as respiratory gas solubility, density, viscosity, vapor pressure, and lipid solubility. Thus, it is critical to choose the appropriate PFC for a specific biomedical application, such as liquid ventilation, drug delivery or blood substitutes. The physical properties of PFC liquids vary substantially; however, the one common property is their high solubility for respiratory gases. In fact, these liquids carry more oxygen and carbon dioxide than blood.
