What it means
Cyanosis is a bluish or purplish discoloration of the skin, lips, or fingertips caused by low oxygen levels in the blood. It is a serious warning sign that the body is not getting enough oxygen. Causes include severe asthma attacks, pneumonia, heart failure, pulmonary embolism, and congenital heart defects. Central cyanosis affects the lips and tongue, while peripheral cyanosis appears in the fingers and toes. Cyanosis in adults or children should be treated as a medical emergency. Call 911 immediately if you or someone else shows signs of cyanosis, especially with difficulty breathing or chest pain.
