Which of the following changes in pulmonary function would you expect in patients > 60 years of age?
A.
a predictable decline in PaO2
B.
a smaller loss of FEV1 compared to FVC
C.
a marked loss of respiratory muscle strength
D.
a greater decline in DLCO in women than in men
E.
all of the above
Which of the following is NOT TRUE of measurements of airway reactivity in the elderly (> 60 years of age)?
A.
Airway reactivity is diminished compared to younger adults
B.
Airway reactivity is often increased compared to younger adults
C.
Airway reactivity may be related to the cumulative effect of smoking or environmental exposures
D.
Is sometimes useful for distinguishing asthma from other causes of dyspnea or wheezing.
Knowing that emphysema is a characteristic of the aging lung, how does one distinguish emphysema due to the aging process vs. that due to disease?
A.
Reductions in actual values for DLCO and FEV1 generally indicate emphysema
B.
Reductions in values for DLCO and FEV1 compared to age and sex matched controls can indicate emphysema.
C.
Only through pulmonary compliance curves is it possible to distinguish emphysema in the elderly.
D.
CT scans are not generally useful for distinguishing pulmonary emphysema
E.
A 20% increase in post-bronchodilator FEV1 is characteristic of emphysema
