This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Anaesthesia
[{'content': 'Which of the following inhalational agents has the minimum blood gas solubility coefficient ? \nSelect and explain. \nA. Isoflurane, B. Sevoflurane, C. Desflurane, D. Nitrous oxide', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Desflurane has minimum blood : gas partition coefficient (minimum blood solubility) → fastest onset and recovery\xa0amongst inhalational anaesthetic agents.\nSpeed of onset & recovery in decreasing order\xa0(Increasing order of B : G partition coefficient & blood solubility)\xa0:-\n\nDesflurane (0.42) >\xa0cyclopropane (0.44) > N2O (0.47) > Sevoflurane (0.69) > Isoflurane (1.38) > Enflurane (1.8) > Halothane (2.4) > Chloroform (8) > Trilene (9) > Ether (12) > Methoxyflurane (15).\n\nDiffusion coefficient also will be in the same decreasing order → desflurane has minimum diffusion coefficient and methoxyflurane has maximum diffusion coefficient.', 'role': 'assistant'}]
