Overview
Cyanosis occurs because of increased concentration of deoxygenated hemoglobin in the capillary bed. Cyanosis is commonly caused by respiratory disorders that inhibits oxygen from reaching the alveoli or interrupt its movement across the alveolar interface. It is also seen in a wide variety of cardiac and vascular disorders by mixing oxygenated blood with deoxygenated blood (eg, vascular shunts or intracardiac shunts), structural or vascular alteration in pulmonary blood flow, cardiac decompensation with pulmonary edema, or shock.
Causes
Cyanosis can be caused by the following mechanisms, systemic arterial oxygen desaturation and increased oxygen extraction by the tissues. Based on these mechanisms, cyanosis can be either central or peripheral. Certain conditions present with bluish purple discoloration of skin or mucous membranes can mimic cyanosis, are not associated with hypoxemia or peripheral vasoconstriction and is called Pseudocyanosis.
Common causes:
Central cyanosis:
There following are some of the common causes of central cyanosis:
- Pulmonary causes:
- Conditions associated with decreased concentration of inspired oxygen (FiO2):[1]
- Smoke inhalation most commonly from house fires
- Carbon monoxide poisoning
- Hydrogen cyanide poisoning
- Intentional or unintensional exposure to asphyxiating gases (eg, Propane, methane, butane, hydrogen sulphide)
- Impairment of chest wall or lung expansion:
- External compression
