cyanosis
Skin turns blue
Cyanosis is a bluish discoloration of the skin and mucous membranes caused by insufficient oxygen in the blood.
It typically appears around the lips, fingertips, and nail beds.
The condition signals respiratory or circulatory problems—anything from cold exposure to serious heart or lung disease.
The infant's cyanosis prompted immediate intervention.
