Cyanosis, also known as cyanosis, is a clinical manifestation in which the skin and membranes appear purplish-blue due to an increase in reduced hemoglobin in the blood or the presence of abnormal hemoglobin derivatives, such as methemoglobin and hemosulfide hemoglobin, in the blood. Cyanosis can appear in the whole body skin and my membrane, but in the thin skin, less pigmented and capillary-rich blood circulation endings, such as lips. It is more easily observed on the tongue, oral level membranes, tip of the nose, cheeks, earlobes, and nail beds. Sometimes xanthosis, edema, or abnormal pigmentation can mask the presence of cyanosis. Good natural light is necessary for early detection of cyanosis. What symptoms can cyanosis be easily confused with? 1, edema with dyspnea, cyanosis: the body tissue interstitial excessive fluid accumulation is called edema. Cyanosis refers to the purple color of lips and nails. Edema with dyspnea and cyanosis suggests that it is caused by heart disease, foot disease and superior vena cava obstruction syndrome. 2, cyanosis and blood hypoxia: tetralogy of Fallot is a common congenital cardiovascular malformation, the first in cyanosis congenital heart disease. The most common main clinical symptoms of tetralogy of Fallot are cyanosis and blood hypoxia. The time of presentation and severity of clinical symptoms depend on the degree of right ventricular outflow tract obstruction and the amount of blood flow in the pulmonary circulation. 3, neonatal cyanosis: cyanosis, also known as cyanosis or cyanosis, is a common symptom of neonatal disease. Newborns are infants within four weeks of birth. The discovery of newborns with symptoms of cyanosis should immediately draw attention to the timely consultation and treatment, so as not to cause the deterioration of the condition. Cyanosis in newborns should be treated with oxygen enrichment. Cyanosis indicates a lack of oxygen in the body, which may cause damage to the brain, heart, kidneys, lungs and other vital organs of the newborn, thus affecting its intellectual and physical development. If you are at home, you can reach your newborn’s need for oxygen by inhaling oxygen-enriched oxygen. Avoid irreversible damage to organ development and intellectual development due to prolonged hypoxia.
