Definition: Pulmonary edema is a condition that is caused by too much fluid in the lungs. The fluid collects in the tiny air spaces known as the alveoli, the place where oxygen and carbon dioxide is exchanged. Once the alveoli become filled with fluid, gas exchange is impaired, resulting in symptoms of pulmonary edema such as anxiety, restlessness, shortness of breath, wheezing, excessive sweating, cough and the coughing up of bloody sputum.

Most often caused by heart failure, pulmonary edema may also occur as a result of pneumonia or other infections, drug overdose, exposure to high altitudes, kidney failure or shock due to excessive bleeding.
