Question 8

Question
Diffusion of Gases is influenced by
Answer
  • Laws of diffusion
  • Measurement of diffusing capacity
  • O2 uptake along the pulmonary capillary
  • Diffusion and perfusion limitations

Question 9

Question
Diffusion through tissue's is described by [blank_start]Fick[blank_end]'s Law
Answer
  • Fick

Question 10

Question
For diffusion through a tissue sheet, the amount of a gas transferred is proportional to [blank_start]Area available for diffusion (A)[blank_end], [blank_start]Diffusion constant (D)[blank_end], [blank_start]Difference in partial pressure (P1‐P2)[blank_end] and inversely proportional to [blank_start]thickness of the tissue (T)[blank_end]
Answer
  • Diffusion constant (D)
  • Difference in partial pressure (P1-P2)
  • Difference in partial pressure (P1‐P2)
  • Diffusion constant (D)
  • Area available for diffusion (A)
  • Area available for diffusion (A)
  • Diffusion constant (D)
  • Difference in partial pressure (P1-P2)
  • thickness of the tissue (T)
  • Area available for diffusion (A)
  • Diffusion constant (D)
  • Difference in partial pressure (P1‐P2)
  • thickness of the tissue (T)
  • thickness of the tissue (T)
  • thickness of the tissue (T)

Question 11

Question
Diffusion constant is [blank_start]proportional[blank_end] to the gas solubility (Sol) and [blank_start]inversely proportional[blank_end] to square root of its molecular weight.
Answer
  • proportional
  • inversely proportional

Question 12

Question
Which diffuses into the lungs quicker? CO2 or O2?
Answer
  • CO2
  • O2

Question 13

Question

Answer
  • Co
  • N2O
  • O2
  • CO2

Question 14

Question
Transfer of CO is [blank_start]diffusion limited[blank_end]. Amount taken up depends on how much CO is available
Answer
  • diffusion limited

Question 15

Question
N2O transfer is [blank_start]perfusion limited[blank_end]. Amount taken up depends on how much blood can flow through
Answer
  • perfusion limited

Question 16

Question

Answer
  • 0.75s
  • 0.8s
  • 0.6s
  • 0.65s
  • 0.7s

Question 17

Question
During exercise how low can the time a RBC spends in an alveolar capillary drop to?
Answer
  • 0.25s
  • 0.2s
  • 0.15s
  • 0.1s

Question 18

Question
Which of the following are measurements of diffusing capacity?
Answer
  • Single breath method
  • Doubly Indirect method
  • Quick exhale method
  • 24hr monitoring method

Question 19

Question
What is the normal value of diffusing capacity for CO at rest?
Answer
  • 25 mL∙min‐1∙mm Hg‐1
  • 30 mL∙min‐1∙mm Hg‐1
  • 20 mL∙min‐1∙mm Hg‐1
  • 15 mL∙min‐1∙mm Hg‐1

Question 20

Question
What is the ratio of breath alcohol to blood alcohol?
Answer
  • 2,100:1
  • 210:1
  • 2200:1
  • 220:1

Question 21

Question
At rest, the PO2 of the blood virtually reaches that of the alveolar gas after about 1/3 of its time in the capillary so O2 transfer is really only limited by [blank_start]perfusion[blank_end]
Answer
  • perfusion
