Pulmonary edema is a respiratory disease caused by the leakage of tissue fluid from inside and outside the pulmonary capillaries into the alveoli, interstitium and small bronchi, resulting in severe impairment of pulmonary ventilation and air exchange. Pulmonary edema is serious and life-threatening and requires prompt treatment. Pulmonary edema mainly includes cardiogenic pulmonary edema and non-cardiogenic pulmonary edema. The treatment of cardiogenic pulmonary edema mainly includes: 1, oxygen: can improve the permeability of pulmonary vessels. 2, reduce venous reflux: take a semi-recumbent or sitting position with legs hanging down. 3.Morphine intravenous push can dilate the peripheral blood vessels: reduce the anxiety state. Contraindicated in patients suffering from severe respiratory coma. 4.Sidiram intravenous pumping: enhance cardiac contraction and increase cardiac output. 5, tachypnea intravenous pumping: diuretic to reduce edema. 6.Nitroprusside vasodilators: specific medication should be prescribed by a specialist according to the patient’s clinical symptoms and examination results. Non-cardiogenic pulmonary edema refers to pulmonary edema caused by causes other than the heart. The main treatment is to actively search for the cause of the disease: for infectious pulmonary edema, the main treatment is to control the infection and administer oxygen; for pulmonary edema caused by uremia, the main treatment is dialysis; for plateau pulmonary edema, the main treatment is to correct hypoxia by administering oxygen and actively resuscitate, etc. There are many causes of pulmonary edema, the main active search for the cause and treatment for the cause. It is recommended that patients with symptoms of cough, shortness of breath and pink foamy sputum should actively consult the respiratory department or cardiology department to have a treatment plan formulated by a specialist.
