CVP and GI Pathology Exam 3 Practice

Chronic bronchitis typically causes chronic hypoxemia with V/Q mismatch, so deoxygenated blood accumulates and cyanosis appears not just in one spot but across mucous membranes and skin (the blue bloater pattern). Emphysema tends to preserve oxygenation longer and patients often look less cyanotic. So the feature that supports the statement is generalized cyanosis seen in chronic bronchitis, reflecting widespread hypoxemia.
