Correct answer: D — 22.8°C
Desflurane boils at 22.8°C which is close to room temperature. This means it would boil uncontrollably in a conventional vaporiser. The Tec 6 vaporiser heats desflurane to 39°C at 2 atm and electronically controls vapour output. Sevoflurane boils at 58.5°C / isoflurane at 48.5°C / halothane at 50.2°C.
