What is non cardiogenic pulmonary oedema?

Noncardiogenic pulmonary edema is a disease process that results in acute hypoxia secondary to a rapid deterioration in respiratory status. The disease process has multiple etiologies, all of which require prompt recognition and intervention.

What causes non cardiogenic pulmonary edema?

Causes of noncardiogenic pulmonary edema include: Acute respiratory distress syndrome (ARDS). This serious disorder occurs when the lungs suddenly fill with fluid. Many conditions can cause ARDS , including severe injury (trauma), widespread infection (sepsis), pneumonia and severe bleeding.

What is the most common cause of cardiogenic pulmonary edema?

Congestive heart failure is a common cause of cardiogenic pulmonary edema; in this condition, the left ventricle cannot pump out enough blood to meet the needs of the body.

What causes pulmonary oedema?

Pulmonary oedema can occur because of the following reasons: An increase in pressure in the blood vessels in the lungs. This often occurs with heart failure, where the heart is pumping blood less efficiently. Damage to the very small blood vessels (capillaries) in the lungs, allowing more fluid to pass into the lungs.

How do cardiogenic and non cardiogenic pulmonary edema differ?

Noncardiogenic pulmonary edema is caused by changes in capillary permeability as a result of a direct or an indirect pathologic insult, while cardiogenic pulmonary edema occurs due to increased capillary hydrostatic pressure secondary to elevated pulmonary venous pressure.

How is non cardiac pulmonary edema treated?

Treatment is carried out with the aim of repairing the alveolar capillary membrane and preventing extension of the damage. Respiratory insufficiency is treated by a mechanical respirator, applying positive pressure at the end of expiration. Fluid administration is adjusted according to pulmonary cone pressure levels.
