<prompt> Arrange following inhalational anesthetic agents according to increasing MAC values i Isoflurane ii Desflurane iii Sevoflurane iv Halothaneiv, i, iii, iiiv, iii, i, iiii, iv, iii, ii, ii, iii, iv  <response>: MAC: Minimum alveolar concentration of inhalational agent required to produce no movement on surgical stimulus in 50 of test patients. Eg: N2O - 104 Halothane - 0.75 Isoflurane - 1.28 Sevoflurane- 2 Desflurane- 6 Less MAC- high potency High MAC- low potency Most potent inhalational agent- Methoxyflurane Least potent inhalational agent- N2O
