Having a bluish discoloration of the skin or mucous membranes due to lack of oxygenated blood.
From cyanose (to become blue) + -ed (past tense/adjective marker). The root cyano- comes from Greek kyanos meaning dark blue.
A cyanosed baby is one of the most alarming sights for new parents, but it can range from serious (a sign of heart or lung problems) to completely harmless (just a newborn's temporary circulation adjustment)—context is everything in medicine.
