Pulmonary fibrosis is associated with a decrease in lung compliance.Individuals with pulmonary fibrosis:
A)Have a higher airway resistance than do individuals with normal lungs.
B)Require a higher transpulmonary (translung)pressure for a change in lung volume than do individuals with normal lungs.
C)Have a shift in their oxyhemoglobin dissociation curve to the right.
D)Have an increase in dead space.

Question

Quizplus · Accepted Answer

Pulmonary fibrosis results in increased stiffness of the lungs, which causes a decrease in lung compliance. This means that a higher transpulmonary (translung) pressure is required to achieve the same change in lung volume as compared to individuals with normal lungs. Option A is incorrect because airway resistance is not directly affected by pulmonary fibrosis. Option C is also incorrect because there is no evidence that pulmonary fibrosis leads to a shift in the oxyhemoglobin dissociation curve. Option D is also incorrect because pulmonary fibrosis does not cause an increase in dead space.
