Bronchitis Sign #10: Cyanosis
Cyanosis refers to the purplish or bluish discoloration of the mucous membranes or skin due to low oxygen saturation. It can be divided into peripheral and central cyanosis. Central cyanosis can usually be seen from the bluish tongue or lips. It can be seen in seizures, bronchitis, pneumonia, heart disease, heart failure, polycythemia, hypothermia, and more.
Peripheral cyanosis can be seen when there is bluish tint on the extremities due to reduced cardiac output, venous obstruction, cold exposure, peripheral vascular disease, and more. Cyanosis usually occurs in more severe or advanced bronchitis.
