The survival time of pulmonary edema cannot be generalized and is related to the primary disease causing it. For example, pulmonary edema due to acute left heart failure from a transient cause usually does not affect life expectancy if treated aggressively, whereas for pulmonary edema due to severe pulmonary hypertension, congenital heart disease, etc., the patient’s life expectancy depends on the primary disease. Survival of patients with pulmonary edema depends on the severity of the primary disease and treatment. Pulmonary edema due to acute myocardial infarction, massive myocardial necrosis, and acute left heart failure can be significantly relieved in most patients through active treatment of the primary disease and treatment of anti-heart failure and protection of cardiac function. However, if no attention is paid to cardiopulmonary care, pulmonary edema may occur due to infectious exertion and violent emotional fluctuations, and if the patient is unable to go to the emergency department of the hospital in time, respiratory and circulatory failure may occur at any time, which may lead to sudden death. The survival of patients with pulmonary edema caused by malignant tumors, chronic obstructive pulmonary disease, and severe pulmonary hypertension depends on the progress of the primary disease. In addition to active hospitalization and treatment, patients with pulmonary edema need to pay attention to rest, ensure sufficient sleep, regular rest and rest, avoid exertion, and maintain a low-salt diet appropriately.
