  3. What has a lower MAC, NO or Halothane?
  4. What is the Blood/gas coefficeint?
    proportion of the gas bound to albumin in blood compared to the free amount of it in the CNS
  5. NO or halothane has a lower Blood/gas coefficeint?
  6. A low Blood/gas coefficeint means what?
    rapid induction and recovery from anesthesia
  7. Where do anethetics redistribute and may cause side effects after the anesthetic wears of?
