Which outcome follows restricted alveolar diffusion rates in patients with emphysema?

A)Decreased arterial oxygen partial pressure
B)Increased carbon dioxide elimination rate
C)Elevated red blood cell production rate
D)Reduced binding affinity for hemoglobin

💡 Explanation

Reduced alveolar diffusion from emphysema leads to low arterial oxygen because gas exchange driving partial pressures decreases in the lungs; therefore, oxygen blood content diminishes rather than enhancing CO2 clearance or hematopoiesis changes.
