At rest, most people require an alveolar ventilation for 4l/minute.Suppose an emphysema victim with a tidal volume of 0.5l has suffered alveolar damage that has produced a respiratory dead space of 0.3l, what will be that persons frequency of breathing at rest? A. 5 breaths/min B. 8 breaths/min C. 20 breaths /min D. 50 breaths / min?

f = A / (T - D)
=> (4000ml/min) / (500 ml - 300 ml)
=> 4000 / 200
=> 20 breaths/min
=> (4000ml/min) / (500 ml - 300 ml)
=> 4000 / 200
=> 20 breaths/min

Alveolar Ventilation
At rest, most people require an alveolar ventilation of 4L/minute. Alveolar ventilation refers to the volume of fresh air that reaches the alveoli (tiny air sacs in the lungs) per minute. It is an important measure as it determines the amount of oxygen available for gas exchange and the removal of carbon dioxide from the body.
Emphysema and Respiratory Dead Space
Emphysema is a chronic lung condition characterized by the destruction of the alveoli walls, leading to reduced gas exchange and impaired lung function. In this case, the emphysema victim has a tidal volume of 0.5L, which is the volume of air inhaled and exhaled in a normal breath.
Respiratory dead space refers to the portion of the tidal volume that does not participate in gas exchange. It includes the air that remains in the conducting airways and does not reach the alveoli. In this case, the respiratory dead space is 0.3L.
Calculating the Frequency of Breathing
To calculate the frequency of breathing, we need to determine the total volume of air that reaches the alveoli per minute, considering the tidal volume and the respiratory dead space.
Total Volume of Air reaching Alveoli per minute = Tidal Volume - Dead Space
Total Volume of Air reaching Alveoli per minute = 0.5L - 0.3L = 0.2L
Now, we can calculate the frequency of breathing using the formula:
Frequency of Breathing = Alveolar Ventilation / Total Volume of Air reaching Alveoli per minute
Frequency of Breathing = 4L/min / 0.2L = 20 breaths/min
Therefore, the person's frequency of breathing at rest would be 20 breaths/minute (Option C).
Summary
- Alveolar ventilation refers to the volume of fresh air reaching the alveoli per minute.
- Emphysema is a lung condition characterized by the destruction of alveoli walls.
- Respiratory dead space is the portion of the tidal volume that does not participate in gas exchange.
- The frequency of breathing can be calculated by dividing the alveolar ventilation by the total volume of air reaching the alveoli per minute.
- In this case, the person's frequency of breathing at rest would be 20 breaths/minute.

Emphysema and Respiratory Dead Space
Emphysema is a chronic lung condition characterized by the destruction of the alveoli walls, leading to reduced gas exchange and impaired lung function. In this case, the emphysema victim has a tidal volume of 0.5L, which is the volume of air inhaled and exhaled in a normal breath.
Respiratory dead space refers to the portion of the tidal volume that does not participate in gas exchange. It includes the air that remains in the conducting airways and does not reach the alveoli. In this case, the respiratory dead space is 0.3L.
Calculating the Frequency of Breathing
To calculate the frequency of breathing, we need to determine the total volume of air that reaches the alveoli per minute, considering the tidal volume and the respiratory dead space.
Total Volume of Air reaching Alveoli per minute = Tidal Volume - Dead Space
Total Volume of Air reaching Alveoli per minute = 0.5L - 0.3L = 0.2L
Now, we can calculate the frequency of breathing using the formula:
Frequency of Breathing = Alveolar Ventilation / Total Volume of Air reaching Alveoli per minute
Frequency of Breathing = 4L/min / 0.2L = 20 breaths/min
Therefore, the person's frequency of breathing at rest would be 20 breaths/minute (Option C).
Summary
- Alveolar ventilation refers to the volume of fresh air reaching the alveoli per minute.
- Emphysema is a lung condition characterized by the destruction of alveoli walls.
- Respiratory dead space is the portion of the tidal volume that does not participate in gas exchange.
- The frequency of breathing can be calculated by dividing the alveolar ventilation by the total volume of air reaching the alveoli per minute.
- In this case, the person's frequency of breathing at rest would be 20 breaths/minute.
