A. While impaired mucociliary clearance can contribute to respiratory symptoms in COPD, it is not directly reflected in the PaCO2 level.
B. In COPD, the respiratory drive can be blunted, leading to inadequate response to elevated PaCO2 levels by the chemoreceptors.
C. Reflex bronchoconstriction may occur in response to various stimuli but is not directly related to the PaCO2 level.
D. Filtration of air primarily refers to the removal of particulate matter and pathogens by the respiratory system and is not directly related to PaCO2 levels.
