It consists primarily of water with trapped aerosolized droplets from the airway lining fluid, as well as water-soluble volatile and nonvolatile compounds. Left ventricle LV failure is the most common and results in decreased cardiac output and increased pulmonary venous pressure.

The development of pulmonary edema may be associated with symptoms and signs of “fluid overload”; this is a non-specific term to describe the manifestations of right ventricular failure on the rest of the body and includes peripheral edema swelling of the legs, in general, of the “pitting” variety, wherein the skin is slow to return to normal when pressed uponraised jugular venous pressure and hepatomegalywhere the liver is enlarged and may be tender or even pulsatile. Acute cardiogenic pulmonary edema often responds rapidly to medical treatment.
