Pulmonary congestion? What's going on?

Causes of pulmonary congestion can be divided into cardiogenic and non-cardiogenic two major causes, cardiogenic pulmonary congestion is mainly due to elevated heart pressure, resulting in an acute pulmonary edema disease, such as coronary artery disease, myocarditis, mitral valve insufficiency, etc. Increased heart pressure will cause the heart's blood return function weakened, blood flow back to the lungs forced blood through the capillary wall to push lung air sacs, resulting in pulmonary congestion symptoms manifested. The main causes of non-cardiogenic pulmonary congestion are viral pneumonia, high altitude pulmonary edema, pulmonary embolism, etc. The capillaries in the lung tissue are affected by the disease, and become more permeable and leaky, so the symptoms of pulmonary congestion are shown. once the symptoms of pulmonary congestion are shown, it is necessary to send the hospital for treatment as soon as possible. If the treatment is not timely, it is likely to endanger life safety.
