Question 2: The Blood gas partition coefficient of Desflurane is 0.42. This would mean:

  1. At equilibrium, the concentration of Desflurane in the blood is 42 percent of alveoli.

  2. The aqueous form of Desflurane is 42 percent of dissolved form.

  3. When compared to Halothane that has a blood gas partition coefficient of 2.4, the uptake of Desflurane is 6 times faster than Halothane.

  4. Only nitrous oxide has a blood gas partition co-efficient lower than desflurane
