"Steve may have emphysema, which is a type of obstructive lung disease. The alveoli are damaged and may collapse, which interferes with pulmonary ventilation. Choose the lung volumes and capacities that you would expect to be above normal in Steve’s condition."

I apologize for the confusion in my previous responses. In emphysema, which is a type of obstructive lung disease, certain lung volumes and capacities are affected. Here are the changes you would expect in Steve's condition:

1. Functional Residual Capacity (FRC): FRC is often increased due to the difficulty in expelling air, leading to air trapping.
2. Total Lung Capacity (TLC): TLC can be increased or normal. It may be elevated due to increased FRC, but in some cases, TLC may remain relatively unchanged.
3. Residual Volume (RV): RV is increased because the damaged alveoli lead to air trapping, making it difficult for the lungs to fully exhale.

These changes are characteristic of obstructive lung diseases like emphysema, where the ability to exhale air is impaired, leading to increased residual volume and, in turn, increased functional residual capacity. I appreciate your understanding, and I apologize for any confusion caused by my previous responses.
