The static pressure-volume curve shown in the figure indicates the presence of which of the following?

Question

Quizplus · Accepted Answer

The static compliance (C_S)line shown in the figure is normal.However,the dynamic compliance (C_D)curve shows that with increasing volumes there are very high pressure increases.This shows a right shift and flattening of the C_D curve and is indicative of increasing airway resistance.Bronchospasm causes an increase in airway resistance.Atelectasis,pneumonia,and pneumothorax will cause both the C_S and C_D curves to shift right and flatten.
