What triad of obstructive lung diseases classify COPD?

A patient exhibits an FEV 1.0: 44% of predicted, FEV 1%: 41% of predicted. What is the most likely problem?

    A.         B.       C.        D.         E.          F. In the graph provided, which flow-volume loop represents a restrictive lung defect?

Upon obtaining a flow volume loop from a patient, you immediately notice the middle portion of the expiratory curve appears “scooped out”. What could be the problem?

While conducting a nitrogen washout study, you notice a spike in the nitrogen % value. Which of the following may NOT be an explanation for this phenomenon?
