Equipotent Alveolar Concentrations of Methoxyflurane, Halothane, Diethyl Ether, Fluroxene, Cyclopropane, Xenon and Nitrous Oxide in the Dog

The minimum alveolar concentration of anesthetic (MAC) required to prevent response to a painful stimulus was determined in dogs for 7 agents. These equipotent concentrations (in volumes per cent at sea level) were: methoxyflurane 0.230, halothane 0.87, diethyl ether 3.04, fluroxene 6.0, cyclopropan
