<prompt> Blood: Gas B:G partition coefficient is a measure of -Potency of anaesthetic agentSpeed of induction and recoveryLipid solubility of agentNone  <response>: Ans. is b i.e., Speed of induction and recovery o B : G partition coefficient is the measure of solubility of agent in the blood.Blood : Gas partition coefficient B : G cofficiento It is the measure of solubility of the agent in the blood. Agent with low blood solubility low B : G coefficient will have high concentration in alveolar air as it will diffuse less through the alveolar capillary membrane because of low blood solubility. Since alveolar concentration determines the induction and recovery, induction recovery will be fast with agent with less B : G partition coefficient; and induction recovery will be slower with agents with high B : G partition coefficiento Desflurane has minimum B: G partition coefficient least blood solubility. Has Fastest onset and recovery.o Methoxyflurane has maximum B : G partition coefficient Maximum blood solubility. Has slowest onset recovery.o Speed of onset recovery; in decreasing order Increasing order of B : G partition coefficient and blood solubilityDesflurane 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.
