Do Volatile Anesthetics Act as Ideal Gases?

Under conditions of temperature and pressure commonly found in operating rooms, the anesthetics enflurane, halothane, and isoflurane act as nearly ideal gasses even at concentrations producing a saturated vapor phase. The deviations from ideality are 3.44 ± 0.44% (SEM) for enflurane, 0.94 ± 0.30% for halothane, and 2.96 ± 0.29% for isoflurane. That is, 0.9 to 3.4% more anesthetic is vaporized than would be predicted from the vapor pressure of these agents.
