- a measure of how easilty a liquid does what?
- what two have high vapor pressures?

Q
(MAC)
- what is the MAC?
- MAC reflects the brain partial pressure because what is in equilibrium with the brain?
- what X the MAC will keep 99% of animals anesthetized?
A
- the concentration (or partial pressure) of anesthetic in the alveolus that will keep 50% of the animals anesthetized during a painful stimulus
- the alveolar partial pressure
- 1.3
6
Q
(solubility)
- solubility of anesthetics in blood and tissues determines the time necessary for equilibration between the two phases to occur
- If an inhalant has a long induction and recovery, how soluble will it be in blood?
A
- very soluble
