10 COPD Symptoms

Symptom #10: Cyanosis
Cyanosis refers to the bluish or purplish discoloration of the mucous membranes or skin due to low oxygen saturation. It is often classified as central or peripheral cyanosis. Central cyanosis is observed when there is bluish or purplish discoloration around the lips, tongue, and core. It is often due to issues of the lungs or heart, leading to poor oxygenation of the body.
Central cyanosis occurs in pneumonia, pulmonary embolism, heart failure, COPD, and more. Peripheral cyanosis occurs when the extremities gain a bluish tint which indicates that there may be obstructed or inadequate circulation. This can be seen in reduced cardiac output, cold exposure, COPD, arterial obstruction, and venous obstruction.
