← Human Body & HealthWhich 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.
