Is called pulmonary edema to the accumulation of fluid inside the lungs. If it occurs within a short period of time, it is usually called acute pulmonary edema and, in this case, it is a medical emergency, since the respiratory capacity of the patient may be compromised.
Because it happens? Causes of pulmonary edema
The lungs fill with fluid when the blood that is normally inside the blood vessels exits outward, flooding the pulmonary alveoli. Of course, this only happens when something goes wrong in the lungs or in the heart; thus, we can divide the lung edema into the following types:
- Cardiogenic lung edema
- Non-cardiogenic lung edema
- Neurogenic pulmonary edema
All of them have in common that they cause a sensation of shortness of breath, which is also known as dyspnoea.
The most common cause of pulmonary edema is usually a congestive heart failure, which in turn may be caused by a sudden rise in blood pressure, aortic valves, or heart attacks or myocardial problems.
However, pulmonary edema can also be due to other causes, such as taking certain drugs, kidney failure, lung damage caused by poisonings or infections, being exposed to high altitudes ...
