What reason is pulmonary congestion?

summary

Pulmonary hyperemia is a kind of pulmonary hyperemia caused by left heart failure. Divided into overflow (also known as active) congestion and obstructive (also known as passive) congestion. The former is that the blood flow into the lung is increased, and the outflow is also increased or normal, resulting in excessive filling of pulmonary capillaries. The latter is due to the normal or increased amount of blood flow, and the outflow decreased, causing congestion of the lung. Pulmonary congestion mainly occurs in hot season. On the basis of long-term pulmonary congestion, due to the abnormal increase of blood volume in the lung, the serous components in the blood leak into the alveoli, bronchioles and pulmonary interstitium, causing pulmonary edema. So we must do a good job in the related work of this disease, so what is the cause of pulmonary congestion?

What reason is pulmonary congestion?

First, lung congestion is mainly caused by long-term overcrowding, sultry, inhalation of a large amount of hot air. If there is blood in the sputum caused by accident, it is because of the rupture of microvascular, you will feel sputum in the throat and cause cough, and there will be blood when spitting. In this case, you need to keep the patient in the most comfortable position, take the prone or supine position, but keep the face on the side, so as to prevent the choking caused by the inhalation of hemoptysis into the respiratory tract. Laryngeal trauma bleeding is generally not dangerous, as long as you pay attention to maintenance, can be cured soon.

Second, hyperemia mainly occurs in decompensated heart diseases, such as myocarditis, cardiac dilation and heart failure caused by various toxic diseases. In addition, in pericarditis, a large amount of exudate in the pericardium affects the relaxation of the heart, causing obstruction of pulmonary venous return; When gastrointestinal flatulence occurs, the negative pressure in the chest decreases, the great venous tube is compressed, and the blood flow out of the lung is difficult, which can cause blood stasis pulmonary congestion.

Third: dyspnea, persistent cough and expectoration, combined with the symptoms of the original heart disease, dyspnea can gradually aggravate, the patient can not lie on his back, and even wake up from a dream due to sudden asthma. In addition, there are cyanosis and tachycardia. With the development of the disease, the patients cough up brown sputum, serous phlegm or bloody sputum.

matters needing attention

Pulmonary hyperemia prevention and treatment: tricuspid atresia is a complex cyanotic congenital cardiovascular malformation with poor prognosis and short survival time. About 70% of the patients died within one year after birth. At present, there is no effective preventive measures, the main clinical diagnosis is to identify with other cyanotic congenital heart disease, in order to timely and correct treatment of children.
