Pulmonary edema (UK/Ireland: oedema) is fluid accumulation in the lungs. This fluid collects in air sacs in the lungs, making it difficult to breathe. It leads to impaired gas exchange and may cause respiratory failure.
According to Medilexicon's medical dictionary, pulmonary edema is: "edema of lungs usually resulting from mitral stenosis or left ventricular failure."
In most cases, heart problems cause pulmonary edema. But fluid can accumulate for other reasons, including pneumonia, exposure to certain toxins and medications, and exercising or living at high elevations.
Treatment depends on the cause, but it focuses on maximizing respiratory function and removing the source of the problem. It generally includes supplemental oxygen and medications.
When pulmonary edema develops suddenly, it is a medical emergency requiring immediate care. Pulmonary edema can sometimes be fatal. The outlook depends on the rapidity in receiving treatment along with treatment for the underlying problem.
