A newborn could turn blue or cyanotic due to various causes such as respiratory problems preventing fresh air to enter into lungs, lack of oxygen in the bloodstream, lack of oxygen binding to hemoglobin, heart not pumping enough blood out of the skin, or freezing tissues unable to profuse blood.
A newborn turning blue is also known as infant methemoglobinemia or blue baby syndrome. The skin of the baby turns blue due to a lack of oxygen in the blood. It is a condition that babies develop at the time of birth. This condition can also be acquired in the early years of growth.
There are various causes behind this syndrome such as pulmonary emphysema in which small airways are damaged in the lungs, making it difficult for the baby to breathe air in and out. This results in a lack of oxygen in the body.
Lack of fresh air in the body leads to a lack of oxygen in the heart and bloodstream. The skin of the babies could also turn blue due to the freezing of tissues, disrupting the normal profusion of blood in the body.
