What can cause cyanosis?

In: Science [Edit categories]

Answer:

Typically oxygen deprivation, but it is common it conditions like hypothermia and hypovolemic shock, where blood is shunted away from the skin to preserve the vital organs. Another cause in neonates is a congenital heart defect known as tetrology of fallot, where venous blood is shunted back through the systemic circulation instead of the pulmonary circulation.
