Chronic obstructive pulmonary disease (COPD) encompasses this category and includes emphysema, chronic bronchitis, asthma, cystic dhanahiantacie DATA ANALYSIS 1. What was the mean tidal volume (TV) for the class? Was it within the expected range of 0.5L/min? If not, what may have accounted for the discrepancy? How does recording this value incorrectly affect your overall results of these pulmonary function tests? 2. Describe the difference between lung volumes for males and females. What might account for this? Explain. 3. Calculate the Minute Volume at rest for the subject of your group. Minute volume at rest = (TV x breaths/minute) If say, Maribel, were taking shallow breaths (TV = 0.20 L) to avoid severe pain from rib fractures, what respiratory rate would she need, so as to achieve the same minute volume that you calculated above for the subject of your group? 4. Exposure to occupational hazards such as coal dust, silica dust, and asbestos may lead to fibrosis, or scarring of lung tissue. With this condition, the lungs become stiff and have loss of elasticity. What would happen to Vital Capacity under these conditions? Explain. 5. In severe emphysema there is destruction of lung tissue and reduced recoil. What would you expect to happen to TLC? Explain.
