Induction of inhalational agent is faster.

Answer- B. Combined with nitrous oxideInduction of inhalational agent is faster, if it is combined with nitrous oxide.'The blood:gas paition coelficient is the mainfactor that determines the rate of induction and recovery of an inhalationanaesthesic, and the lower the blood: gas paition coefficient, the faster is induction and recovery.The second gos effect usually refers to nitrous oxide combined with an inhalation agent. Because nitrous oxide is notsoluble in blood, its rapid absorption from alveoli causes an abrupt rise in the alveolar concentration of the otherinhalation anesthetic leading to faster induction.
