The influence of carrier gas on the output of automatic plenum vaporizers
Abstract:
The effect of the physical characteristics of the carrier gas on the output of automatic plenum vaporizers was studied. The Vapor and Fluomatic halothane output at all dial settings was highest with oxygen as the carrier gas, as compared with helium and nitrous oxide and was a function of carrier gas viscosity at all dial settings. The output of the Fluotec Mark 2 at the 0.5 and 1% settings was highest with nitrous oxide as the carrier gas, but at 2, 3 and 4% settings it was highest with oxygen; at the 0.5% and 1% dial settings it was a function of carrier gas density, but at 2%, 3% and 4% it was a function of carrier gas viscosity.
