Is it possible for pulmonary edema to kill you?

Yes....: Pulmonary edema is when there is fluid build up in the lungs. This can occur for a variety of reasons including congestive heart failure, pneumonia, pulmonary embolus, adult respiratory distress syndrome, heart attack, etc. If there is a lot of fluid and if it builds up rapidly, it can be life-threatening or even fatal. So, any sudden onset of shortness of breath should be evaluated in the er!

Absolutely: Many causes of pulmonary edema are fatal. Severe cases prevent the lungs from being able to supply oxygen to tissues.
