(1), pulmonary capillary pressure increased

Found in a variety of causes left heart failure (mitral valve stenosis coronary heart disease Hypertensive heart disease and others) infusion of excessive pulmonary veno-occlusive disease (pulmonary vein fibrosis, congenital pulmonary vein stenosis mediastinal tumor mediastinal granuloma mediastinal Yandeng fibers can be oppressive veins) caused by increased pulmonary capillary pressure inside the blood vessels caused by leakage of fluid produced within the pulmonary edema

(2) increased pulmonary capillary permeability

Bio-physical and chemical substances can be both direct and indirect damage cell membrane permeability leading to pulmonary edema is a common clinical reasons: bacterial or viral pneumonia, radiation pneumonitis Allergic alveolitis inhalation of harmful gases such as phosgene, chlorine ozone-nitrogen oxides oxygen uremia poisoning, drowning and other serious burns DIC

(3) lower plasma colloid osmotic pressure

Such as the liver kidney protein-losing enteropathy and other nutritional hypoproteinemia dropped when the plasma protein g / L or reduced albumin g / L may lead to pulmonary edema following

(4) lymph circulation disorder

When certain diseases such as silicosis and other lung caused by poor lymphatic drainage of interstitial fluid may be stagnant water accumulated pulmonary edema occurred

(5) increased negative pressure tissue space

Sudden airway obstruction, or a short time to remove a large number of pneumothorax, and pleural effusion can be so sudden drop in the formation of pulmonary pressure and negative pressure pulmonary capillary attraction and thus produce pulmonary edema

(6) comprehensive factors or unexplained acute respiratory distress syndrome, high altitude pulmonary edema neurogenic pulmonary edema pulmonary embolism sub-narcotic pain excessive shock cardioversion.
