Figure 70-14
Behavior of an ideal Fluotec vaporizer at 1 and 3 ATA.
If the ratio of the O2
flow (anesthetic vaporizer flow/bypass flow) is
unchanged at different ambient pressures, it can be seen that the partial pressure
of halothane delivered at the exit of the vaporizer is constant. (From Smith
RM: Anesthesia during hyperbaric oxygenation. Ann N Y Acad Sci 117:768, 1965.)
