The types of cyanosis are central and peripheral.
Central cyanosis is caused by a lack of oxygen in the blood due to problems with the heart or lungs. This can lead to a bluish discoloration of the skin, lips, and fingernails.
Peripheral cyanosis is caused by a decrease in the number of red blood cells or an increase in the number of white blood cells. This can lead to a blue coloration of the extremities, such as the fingers and toes.
