Abstract
Halothane, independent of oxygen tension, increased the signal of the gold/silver-silver chloride microelectrode. The output of microelectrodes at different oxygen tensions in the presence of increasing amounts of halothane has been measured. Halothane causes an increase in the electrode signal which is proportional to its concentration. This effect results from the polarographic reduction of halothane. It is concluded that the gold/silver-silver chloride microelectrode cannot be used to measure oxygen tension during halothane anaesthesia.Keywords
