What was the mean tidal volume (TV) for the class? Was itlwithin 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. Anatomical and physiological differences such as body lung capacity, hormonal influences account for these differences! calculate the average of lung volumes for males and females separately, compare averages to identify differences. 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. Exposure to occupational hazards leading to scaming of lung tissue would decrease the vital capacity due to reduced lung compliance and increased stiffress. 5. In severe emphysema there is destruction of lung tissue and reduced recoil. What would you expect to happen to TLC? Explain. (Hint: Think overinflation) In Severe emphysema with destruction of lung tissue and reduced recoil, the total lung capacity would increase due to over inflation of the remaining lung tissue. 6) What is the physiological difference between pulmonary obstructive disorder and pulmonary restrictive disorder?

1. What was the mean tidal volume (TV) for the class? Was itlwithin 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. Anatomical and physiological differences such as
body
lung capacity, hormonal influences account for these
differences!
calculate the average of lung volumes for males and
females separately, compare averages to identify differences.
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.
Exposure to occupational hazards leading to scaming of
lung tissue would decrease the vital capacity due to reduced
lung compliance
and increased stiffress.
5. In severe emphysema there is destruction of lung tissue and reduced recoil. What would you
expect to happen to TLC? Explain. (Hint: Think overinflation) In Severe emphysema
with destruction of lung tissue and reduced recoil, the total
lung capacity would increase due to over inflation of the
remaining lung tissue.
6) What is the physiological difference between pulmonary obstructive disorder and pulmonary
restrictive disorder?
