Review Question - QID 214354

A pulmonologist is consulted about 3 patients who are experiencing shortness of breath. One of the patients has emphysema after smoking 1 pack of cigarettes per day for 45 years. Another patient has idiopathic pulmonary fibrosis and is enrolled in a clinical trial for an experimental medication. The final patient is found to be suffering a panic attack and has no organic lung disease. The pulmonologist superimposes the 3 unlabeled curves from these patients as shown in Figure A. What is the ratio of the lung compliance of the panic attack patient to the lung compliance of the fibrosis patient if both are measured from 10-20 cm H2O of pressure?
