Passage:
Expiration becomes difficult in emphysematous patients because bronchiolar obstruction increases airway resistance. This resistance is already elevated during expiration due to the compressive force on the outside of the lung. Slowing of forced expiration is the most reliable indicator of chronic emphysema
Thought that it should show a smaller total lung capacity? I'm confused
