perfluorocarbon

 [per-floor´o-kahr″bon]
any of various substances chemically related to a hydrocarbons but with the hydrogen atoms replaced by fluorine atoms. In gaseous form they cause environmental damage by collecting in the upper atmosphere; in liquid form, some are used in partial liquid ventilation.

perfluorocarbon

[pərfloo͡r′ōkär′bən]
any of a group of chemicals with limited capacity for transporting oxygen through the circulatory system. They can be used for certain blood substitute purposes, regardless of the blood type of the patient. They are stable at room temperatures, have a pH of 7.4, and are free of infectious pathogens. Also called artificial blood or blood substitute.

perfluorocarbon

(pĕr-floor″-ă-kahr′ bŭn, -floo″ă-rō-)
A class of solvent molecules that can carry nonpolar gases, such as oxygen, nitrogen, and carbon dioxide. They have been used experimentally in transfusion medicine and in some ophthalmic surgeries. Perfluorocarbons are also used as blood gas controls when prepared in buffered solutions equilibrated with CO2 and O2.
