Question 4

(vapor pressure)

1. a measure of how easilty a liquid does what?
2. what two have high vapor pressures?
3. intermediate?

Answer 4

1. evaporates
2. halothane and isoflurane
3. sevoflurane

Question 5

(MAC)

1. what is the MAC?
2. MAC reflects the brain partial pressure because what is in equilibrium with the brain?
3. what X the MAC will keep 99% of animals anesthetized?

Answer 5

1. the concentration (or partial pressure) of anesthetic in the alveolus that will keep 50% of the animals anesthetized during a painful stimulus
2. the alveolar partial pressure
3. 1.3

Question 6

(solubility)

1. solubility of anesthetics in blood and tissues determines the time necessary for equilibration between the two phases to occur
