Acrocyanosis is common initially after delivery in the preterm and full term newborn. [13] Intervention is typically not required as it is seen as a normal finding. Acrocyanosis can also return in a newborn if a baby is cold, such as after a bath, and is considered normal as well. [14]
In newborns, peripheral cyanosis typically presents in the distal extremities, circumoral, and periorbital areas. [9] Of note, mucous membranes remain pink in peripheral cyanosis as compared to central cyanosis where the mucous membranes are cyanotic. [9] An example of cyanosis in an individual with darker skin pigmentation.
In addition to cyanosis, they often show signs of tachypnea (fast breathing), a heart murmur, and decreased peripheral pulses. [6] [31] If congenital heart disease is suspected in a newborn, doctors will likely perform several tests to evaluate the heart, including a chest x-ray, echocardiogram, and electrocardiogram. [32]
cyanotic d-TGA + VSD neonate (unpalliated and pre-operative) Due to the low oxygen saturation of the blood, cyanosis will appear in peripheral areas: around the mouth and lips, fingertips, and toes; these areas are furthest from the heart, and since the circulated blood is not fully oxygenated to begin with, very little oxygen reaches the peripheral arteries.

Adults normally breathe about 14 to 20 times per minute, while infants may breathe up to 44 times per minute. [3] After obtaining the patient's respiratory rate, the examiner looks for any signs of respiratory distress, which may include: Cyanosis, a bluish tinge of the extremities (peripheral cyanosis), or of tongue (central cyanosis) [4]
Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().

Infant with cyanosis due to hypoplastic left heart syndrome. Closing of the ductus arteriosus in a heart that is severely underdeveloped on the left results in cyanosis and respiratory distress which can progress to cardiogenic shock and death. Early symptoms might include poor feeding or cyanosis that does not respond to oxygen administration.
