Poorly ventilated alveoli. Differential cyanosis classically occurs in PDA with reversal of shunt when raised PA pressures /PVR is able to supersede the systemic Aortic pressure and drive the blood from LPA to descending Aorta bringing down the lower limb saturation..

With complete interruption oftheaortic archdistal totheoriginoftheleft sub-clavian artery, cyanosis in botharmsis intense and symmetrical as in our case (Buckley et al., 1965). Bluish discoloration of the skin and/or mucous membranes due to increased quantity of deoxygenated hemoglobin or the presence of hemoglobin derivatives in the small blood vessels . Cyanosis is the change of body tissue color to a bluish-purple hue as a result of having decreased amounts of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. In conditions giving rise to this type of cyanosis, an abnormal amount of reduced hemoglobin is found within the peripheral arterial system.

Pigmentary birthmarks Large tattoos It is important to distinguish these as it can help you to formulate a differential diagnosis and identify cases that are life-threatening. Patients with a large ductus develop progressive pulmonary vascular disease, and pressure overload of the right ventricle occurs. This reduction may be brought about by a decline in the FIO 2 without sufficient compensatory alveolar hyperventilation to maintain alveolar PO 2. Unlike in adults, all hernias in children are repaired at the time of diagnosis because: The risk of incarceration and strangulation is high There is a 30% risk of testicular infarction due to pressure on the gonadal vessels It is not worth messing around and .

When a baby takes its first breath, the lungs expand reducing resistance to blood flow and allowing for more flow from the right ventricle. When limited to the extremities, it is termed peripheral cyanosis or acrocyanosis. When present throughout the body, including the mucous membranes and tongue, the condition is termed central cyanosis. pulmonary hypertension and deoxygenated blood enters the distal subclavian artery.
