<prompt> Which of the following inhalational agents has the minimum blood gas solubility coefficient ?IsofluraneSevofluraneDesfluraneNitrous oxide  <response>: Desflurane has minimum blood : gas partition coefficient minimum blood solubility fastest onset and recovery amongst inhalational anaesthetic agents.Speed of onset recovery in decreasing order Increasing order of B : G partition coefficient blood solubility :-Desflurane 0.42 cyclopropane 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.Diffusion coefficient also will be in the same decreasing order desflurane has minimum diffusion coefficient and methoxyflurane has maximum diffusion coefficient.
