What are the causes of lung edema?

lung edema is a condition where the fluid accumulates in the lung tissue. Many causes of lung edema can be divided into two different groups: cardiogenic and non -cardiogenic. Cardiogenic causes include problems such as cardiac abnormalities, congestive heart failure and myocardial ischemia. Cardiogenic causes include a huge number of states, including lung injuries, sepsis, pancreatitis and transfusions. The range of pulmonary edema depends on osmotic and hydrostatic forces in the lung capillaries.

cardiogenic causes of lung edema include a series of abnormalities of the heart that lead to an increase in lung venous pressure. This increase changes the fine balance between interstitial tissue and pulmonary capillaries. Thus, hydrostatic pressure increases and promotes the collection of fluid into capillaries and then into alveoles. Alveoli are small air bags that are easily filled with liquids in short breath and cough.

Cardiogenic causes of lung edema also include heart conditions as congestive heart failure, IMyocardial, heart attack scheme, and flap abnormalities that lead to the overload of the volume of the left ventricle. The flaps of the lung edema include mitral valve stenosis, regurgitation of the mitral valve and aortic insufficiency. Chamber septal defects that are openings in the heart muscle separating the two lower chambers of the heart can also lead to lung edema.

the non -cardiogenic causes of the lung edema cover a wide range of conditions, including direct lung damage; hematogenic damage or collection of blood in lung tissue; increase in hydrostatic pressure; and chemicals. Edema increases inside the lungs from the leakage of proteins by damaged capillary lining. The fluid monitors the leakage proteins caused by oncotic forces causing the dysfunction of alveoli lined with a surface -active substance. Thus, non -cardiogenic lung edema often manifests itself with severe hypoxia, bluish skin color and significantly reduced lung performance.

lung edema caused by direct lung injury may be the result of aspiration, smoke inhalation and chest trauma. Injuries can also be caused by lung bruise, pneumonia, pulmonary embolism and oxygen toxicity that occurs from the breathing of high oxygen concentrations at high atmospheric pressures. Hematogenic injuries causing pulmonary edema include a range of diseases. These serious conditions include sepsis, disseminated intravascular coagulation (DIC), pancreatitis, multiple transfusions with transfusion reactions, non -shopping trauma and prolonged time for cardiopulmonary bypass during operations.

Some lung lung injuries are caused by increased hydrostatic pressure. For example, the HAPE lung edema (HAPE) Jeakute mountain diseases that occur when people rise to high heights without proper acclimatization. For all causes of lung edema, HAPE has the simplest treatment: descend to lower altitudes.

Another increasedThe hydrostatic pressure may be caused by increased intracerebral pressure, called neurogenic pulmonary edema. Lung edema can also result from re-expansion of lungs after lung collapse. Some of the chemical causes of lung edema include allergy to radiographic contrast allergies, intoxication of salicylate and inhalation toxins, such as smoke inhalation.
