Breathing And Exchange Of Gases Animal Respiration Question 15
Question: At rest, most people require an alveolar ventilation for about 4 L/minute. Suppose an emphysema victim with a tidal volume of 0.5 L has suffered alveolar damage that has produced a respiratory dead space of 0.3 L, what will be that person’s frequency of breathing at rest?
Options:
A) 5 breaths/min
B) 8 breaths/min
C) 20 breaths/min
D) 50 breaths/min
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ f=\frac{A}{T-D}=\frac{4000ml/\min }{500ml-300ml} $ $ \frac{4000}{200}=20breaths/min $
