Abstract:
Perfluorotetramethylcyclohexane shows improved properties for use
in biological gas exchange, both as a blood substitute and as
perfluorocarbon for intra-pulmonary 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.
