Many cases of pulmonary edema are unavoidable. Persons with heart problems should take medications as prescribed. Narcotics should not be abused. Those who are mountain climbing should avoid going beyond 8,000 feet above sea level unless they are experienced or are with a guide.
Severe pulmonary edema can lead to death. Most of the long-term effects are related to the cause of the pulmonary edema. For example, those with severe heart disease may be unable to perform daily activities without getting tired or having shortness of breath. On the other hand, edema from an infection that is successfully treated often causes no long-term effects.
Lung edema is not contagious and does not pose any risk to others.
