You may have noticed that your lips turn purple or blue in the cold, or you may have seen a baby, an elderly person or someone else with bluish or purplish lips. In many cases, this type is caused by cyanosis, which is a discoloration of a part of the body resulting from a lack of oxygen in the blood.
Cyanosis is a bluish color in the skin, lips and nail beds caused by a shortage of oxygen in the blood. Cyanosis occurs because blood with decreased oxygen turns blue or purple. This low-oxygen blood causes a blue-purple tint to the skin. What conditions cause cyanosis? Cyanosis is usually caused by problems of the heart, lungs or blood. Some of the defects or diseases that can cause a child to have cyanosis are: truncus arteriosus. total anomalous pulmonary venous return. transposition of the great arteries. tricuspid atresia. pulmonary atresia. atrioventricular canal defect. pulmonary hypertension.
