Q Lung Volumes and Capacities What was the individual’s Tidal Volume (TV)? What would you expect the TV to be if the individual inhaled a foreign object which completely obstructed the right primary bronchus. 2.Describe the difference between lung volumes for males and females. What might account for this? 3. Calculate your Minute Volume at rest. (TV ? breaths/minute) = Minute Volume at rest If you are taking shallow breaths (TV = 0.20 L) to avoid severe pain from rib fractures, what respiratory rate will be required to achieve the same minute volume? 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 more “recoil.” What would happen to TLC and VC under these conditions?
