Cyanosis color change?

Cyanosis color change?

• A. Redness
• B. Yellowing
• C. Bluish color due to low oxygen
• D. Pallor

Answer: (C)

Cyanosis shows a bluish discoloration because there is more deoxygenated hemoglobin in the blood. When arterial oxygen levels drop, hemoglobin releases its oxygen and the blood—and the tissues it perfuses—take on a blue tint. This is a clinical cue that oxygenation is insufficient, often pointing to respiratory or cardiovascular issues that need attention. Redness is a result of increased blood flow or inflammation, yellowing indicates bilirubin buildup (jaundice), and pallor reflects reduced blood flow or anemia.
