Question

Which of these two parameters changed more for the patient with emphysema, the FVC or the FEV1?

A. FVC changed more
B. FEV1 changed more
C. Both changed equally
D. No significant change observed

Answer 1

In emphysema, the FEV1 changes more compared to the FVC.

Step-by-step explanation:

The FEV1 and FVC are two important parameters measured during spirometry to diagnose lung diseases. In the case of emphysema, the FEV1 is likely to change more compared to the FVC. Emphysema is a type of obstructive lung disease where the airways become narrowed, making it difficult for the patient to exhale air effectively. Consequently, the patient would have a lower FEV1 value compared to the FVC.
