Properties of selected perfluorocarbons [5].

Common name	Chemical formula	Normal boiling point (°C)	Vapor pressure at 37°C (kPa)	Expansion ratio*
Perfluorobutane	C4F10	−1.3	387.98	5.37
Perfluoropentane	C5F12	29.2	135.05	5.17
Perfluorohexane	C6F14	57.1	48.09	4.97

∗Diameter expansion ratio calculated assuming no Laplace pressure compressing the final gas bubble, internal bubble pressure at 1 atm, and temperature of 37°C.
