Abstract:

Normothermic anesthetized dogs ventilated with oxygenated FC-80 fluorocarbon liquid can be maintained at a normal PaCO2 for 1 hr. The use of an emulsion of 1 by volume of 2 M NaOH in FC-80 fluorocarbon liquid should permit a liquid breathing diver to perform work requiring a VO2 of approximately 1 1 STPDmin while maintaining a normal PaCO2. Microscopic examination of the lungs of dogs and rats that had breathed oxygenated FC-80 fluorocarbon liquid or an emulsion of 1 by volume of 2 M NaOH in FC-80 fluorocarbon liquid revealed the transient presence of increased numbers of mononuclear cells but no other pathologic changes.
