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.

When obtaining the history, it is important to determine the timing of symptoms and to ask about risk factors/exposures, such as prenatal history or access to well-water. [29] Pulse oximeter on infant's foot. On physical exam it is important to visualize where the cyanosis is present to differentiate between peripheral and central cyanosis ...
Unless acrocyanosis results from another condition (e.g. malignancy, antiphospholipid syndrome, atherosclerosis, acute ischemic limb, bacterial endocarditis), there is no associated increased risk of disease or death, and there are no known complications. Aside from the discoloration, there are no other symptoms: no pain, and no loss of function.
Early symptoms of hypovolemia include headache, fatigue, weakness, thirst, and dizziness. The more severe signs and symptoms are often associated with hypovolemic shock. These include oliguria, cyanosis, abdominal and chest pain, hypotension, tachycardia, cold hands and feet, and progressively altering mental status. [citation needed]
Signs and symptoms are also applied to physiological states outside the context of disease, as for example when referring to the signs and symptoms of pregnancy, or the symptoms of dehydration. Sometimes a disease may be present without showing any signs or symptoms when it is known as being asymptomatic . [ 13 ]
The perception of dyspnea is theorized to be a complicated connection between peripheral receptors, neural pathways, and the central nervous system. [ 5 ] Receptors in the chest wall and central airways, as well receptors in the respiratory center of the central nervous system, produce an increased requirement for ventilation which is not ...
It is estimated to account for 2-3% of all congenital heart disease. [3] Early signs and symptoms include poor feeding, cyanosis, and diminished pulse in the extremities. [4] The etiology is believed to be multifactorial resulting from a combination of genetic mutations and defects resulting in altered blood flow in the heart.
A cyanotic heart defect is any congenital heart defect (CHD) that occurs due to deoxygenated blood bypassing the lungs and entering the systemic circulation, or a mixture of oxygenated and unoxygenated blood entering the systemic circulation.
