Reviewed: Dr. Mera
Symptom #4: 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 central or peripheral cyanosis. Central cyanosis can be seen at the core, such as the tongues and lips. It can be seen in pneumonia, drug overdose, bronchospasms, pulmonary hypertension, hypoventilation, and cardiovascular diseases.
Peripheral cyanosis is seen at the extremities such as the fingers and toes. It can be seen in all the common causes of central cyanosis, cold exposure, arterial obstruction, and so on. In more advanced cases of an RSV infection, cyanosis may occur as there is low oxygen saturation due to narrowed airways.
