Swelling of the legs complications

With pulmonary edema: consequences, complications, prognosis of the condition of the patient are most interested. Pulmonary tissue is filled with transudate from seeping capillaries and this greatly impairs gas exchange. Characterized by the presence of shortness of breath, lack of air and tightness in the chest.

Causes of development of pulmonary edema

Many diseases can be complicated quicklydeveloping edema of pulmonary tissue. With it, the hydrostatic pressure rises, and the oncotic pressure falls in the pulmonary alveoli, and the integrity of their membranes occurs.

The trigger mechanism of such edema:

  • heart diseases;
  • allergies;
  • diseases of a nephrogenic nature;
  • neurological problems;
  • toxic substances;
  • eclampsia of pregnant women;
  • mechanical asphyxiation.

Pulmonary edema can occur within 1 minute (usually ends with the patient's death) to one or two days. Often has an undulating character.

  • tissue hypoxia;
  • acidosis;
  • violation of gas exchange;
  • fatal organ disorders.

The fluid released into the lung tissue is notabsorbed back. It mixes with air and forms a stable foam that prevents oxygen from flowing to the membranes for further spread through the body.

The progression of edema occurs due to increased pressure of the small circle of circulation, because of shortness of breath, which in turn accelerates the flow of fluids into the surrounding lung tissue.

Complication and prognosis of pulmonary edema

When the onset of swelling, a person quickly loses touch with the world, becomes inhibited, falls into a coma. Often death occurs through asphyxia.

Rapid and timely initiation of treatment andpathogenetic therapy can give a positive prognosis for the development of further events. On average, mortality occurs in 20% of cases with alveolar edema, and in 90% - in case of an infarct or anaphylactic shock.

Timely arresting an attack does not stop the development of organ damage and the development of pneumonia, pneumosclerosis.
