decreased

3

L1: Minimum Alveolar Concentration is _____ly proportional to the potency and lipid solubility of the agent

inversely

4

L1: More lipid soluble anesthetics have ____er potency.

higher

5

1/MAC

6

L1: Rank the rate of uptake into the following tissues from fastest to slowest: vessel-rich, fat, muscle

Vessel-rich > muscle > fat

7

L1: Rate of increase of partial pressure of anesthetic in alveoli and pulmonary capillaries is proportional to the _______.

ventilation rate

8

L1: Solubility in blood is measured by the ______.

Blood:gas partition coefficient

9

L1: Which anesthetic has MAC >100%?

Nitrous Oxide

10

L2: _______ effect: high % of inspired nitric oxide causes uptake ______ than predicted due to large anesthetic volume

Concentration; faster

11

L2: _______: gases co-administered with nitrous oxide have greater than expected uptake

Second Gas Effect

12

L2: _______: when anesthetic is terminated, large nitric oxide diffusion from the blood to alveoli dilutes alveolar oxygen

Diffusion hypoxia
