Title: Improved perfluorocarbons for biological gas exchange and method
Inventor: CLARK LELAND C JR
IPC: A61K31/025
Filed: 1996-11-22
Abstract: Perfluorotetramethylcyclohexane shows improved properties for use in biological gas exchange, both as a blood substitute and as perfluorocarbon for intrapulmonary applications. The material has an adequately low vapor pressure to completely avoid causing hyperinflated lung damage and to increase the interval between required applications. However, the compound has a sufficiently high vapor pressure to produce acceptably brief residence time within the body. A method has been developed for using this novel compound to accelerate the exhalation of very low vapor pressure compounds such as perfluorophenanthrene from the lungs. The addition of perfluorotetramethylcyclohexane, along with perfluorophenanthrene, greatly increases the rate at which the perfluorophenanthrene is exhaled.
