 a. They reduce MAP in direct proportion to their alveolar concentration

 b. Nitrous oxide has a relatively low MAC

 c. Halogenated agents have a lower brain:blood partition coefficient

 d. Nitrous oxide causes a decrease in tidal volume and an increase in respiratory rate

 e. They decrease the metabolic rate in the brain by decreasing cerebral blood flow
