Abnormal findings includes marked redness, cyanosis or extreme pallor. Delayed pulmonary edema, cyanosis or bronchopneumonia may develop. Odynophagia, tachypnea, dyspnea, cyanosis, fever, and shock develop rapidly thereafter. This causes several adverse effects, including hypotension and cyanosis. These neonates quickly decompensate and develop acidosis and cyanosis. Symptoms include hypotonia, apnoeic spells, cyanosis, and impaired metabolic responses to cold stress and seizures. It is characterized by sudden severe pain, swelling, cyanosis and edema of the affected limb. Acute exposure to yttrium compounds can cause shortness of breath, coughing, chest pain, and cyanosis. Patients typically present as neonates with cyanosis or congestive heart failure. Also, the newborn can present with gastric distention, cough, apnea, tachypnea, and cyanosis. This contributes to cyanosis and pulmonary hypertension. This can cause pain, shortness of breath, cyanosis, and, if not treated, death. In acute cases patients may experience cyanosis and circulatory shock. Monitor signs of respiratory distress such as&colon; nasal flaring, grunting, central cyanosis. Later, there are typically episodes of bluish color to the skin known as cyanosis.
