Inhalant Anesthetics

Question 1

Vapor

Answer 1

Gaseous state of substance that is liquid at ambient temp and pressure

Question 2

Gas

Answer 2

exists in gaseous stat at ambient temperature and pressure

Question 3

Dalton’s law of partial pressure

Answer 3

Total pressure of a gas mixture is equal to the sum of the partial pressure of the individual gases

Question 4

Vapor pressure

Answer 4

pressure exerted by vapor molecules when liquid and vapor phases are in equilibrium

Question 5

Saturated vapor pressure

Answer 5

Vapors have a maximum administration percentage

Question 6

Solubility

Answer 6

Anesthetic vapors dissolve in liquids and solids

Equilibrium is reached when the partial pressure of the anesthetic is the same in each phase

Question 7

Partition coefficient

Answer 7

concentration ratio of an anesthetic in the solvent and gas phase

Question 8

Blood-gas partition coefficient

Answer 8

the amount of an anesthetic in the blood vs. alveolar gas at equal partial pressure

Question 9

How do you increase inspired anesthetic concentration?

Answer 9

Increase vaporizer setting
Increase fresh gas flow
decrease breathing circuit volume

Question 10

How do you increase alveolar ventilation?

Answer 10

Increase minute ventilation

decrease dead space ventilation
