WebAbstract. In normal subjects, exercise widens the alveolar-arterial PO2 difference (P [A-a]O2) despite a more uniform topographic distribution of ventilation-perfusion (VA/Q) ratios. While part of the increase in P (A-a)O2 (especially during heavy exercise) is due to diffusion limitation, a considerable amount is caused by an increase in VA/Q ... WebA) a decrease in both alveolar PCO2 and PO2. B) the same alveolar PCO2 as under normal conditions. C) an increase in both alveolar PCO2 and PO2. D) increased alveolar PCO2 …
