Question

With emphysema, there is a significant loss of elastic recoil in the lung tissue and a noticeable, exhausting muscular effort is required for each respiration. Inspiration becomes easier because the lung is now overly compliant. Using the spirogram, calculate the lung volume affected by the emphysema condition

A) Tidal volume
B) Inspiratory reserve volume
C) Expiratory reserve volume
D) Residual volume

Answer 1

Emphysema affects the tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume.

Step-by-step explanation:

In emphysema, there is a loss of elastic recoil in the lung tissue, making each respiration more exhausting. The lung becomes overly compliant, which means inspiration becomes easier.

The lung volumes affected by emphysema include:

1. Tidal volume: The amount of air inhaled and exhaled during normal breathing.
2. Inspiratory reserve volume: The additional amount of air that can be inhaled after a normal inhalation.
3. Expiratory reserve volume: The additional amount of air that can be exhaled after a normal exhalation.
4. Residual volume: The amount of air remaining in the lungs after maximal exhalation.
