Answer :
To become cyanotic is to turn blue. A reduced amount of hemoglobin in the baby's blood could cause the newborn to turn blue.
Methemoglobinemia in infants is often known as "blue baby syndrome". An infant with this condition develops blue skin. This happens when there is not enough oxygen in the blood. Some children are born with methemoglobinemia, or a reduced amount of hemoglobin (congenital), while others develop it later in life (acquired).
Decreased arterial oxygen saturation is the cause of central cyanosis. Because oxygen saturation rises to 85 to 95 percent by the time a baby is 10 minutes old, newborns usually do not develop central cyanosis until 5 to 10 minutes after birth. To be cyanotic is to turn blue. A newborn baby may turn blue if the amount of hemoglobin in the blood is too low.
