Below is a graph summarizing a forced vital capacity for Patients A and B. Volume exhaled (L) Subject A FEV1 Subject B FVC FVC Time (seconds) Answer the following questions: 1. What is the FEV1 for Patient A? 2. What is the FEV1 for Patient B? 3. What is the FVC for Patient A? 4. What is the FVC for Patient B? 5. What is the FEV1 ?FVC ratio for Patient A? 6. What is the FEV1 ?FVC ratio for Patient B? 7. Does either patient have lung disease? If yes, can you tell if it is obstructive or restrictive?

What does FEV1/FVC measure and why will the ratio increase with lung fibrosis? a. the forced expiratory volume in one second in relation to the total forced vital capacity; lung fibrosis causes the lungs to decrease in size b. the functional expiratory volume in one second in relation to the total functional vital capacity; lung fibrosis causes the lungs to decrease in size c. the functional expiratory volume in one second in relation to the total functional vital capacity; lung fibrosis causes the lungs to become less pliable d. the forced expiratory volume in one second in relation to the total forced vital capacity; lung fibrosis causes the lungs to become less pliable

Spirogram: Plot a properly labeled and titled spirogram (line graph) for each patient. Measurements: Determine (calculate) the following pulmonary volumes and pulmonary capacities for each patient (refer to Table 1 in Workshop 6 theory). Pulmonary Volume: Tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), and residual volume (RV). Pulmonary Capacity: Inspiratory capacity, functional residual capacity, vital capacity, total lung capacity. Data Set: Time Volume (l) 0 0 1 4 2 5.5 3 5.5 4 5.5 5 5.5 6 5.5
