Edema is a restrictive lung and cardiovascular disease, which causes excessive movement of fluid from the pulmonary vascular system to the extra vascular system and air spaces of the lungs, heart and various parts of the body. In most cases edema is due to heart failure, which is a condition in which the heart muscle has been damaged and can no longer pump adequate supply of oxygen to the rest of the body. This will increase the blood pressure which will cause fluid to build up in the lungs. If pulmonary edema continues, it can raise pressure in the pulmonary artery and eventually the right ventricle begins to fail. The right ventricle has a much thinner wall of muscle than does the left side because it is under less pressure to pump blood into the lungs. The increased pressure backs up into the right atrium and then into various parts of your body, where it can cause: Leg swelling (edema), abdominal swelling (ascites), buildup of fluid in the membranes that surround your lungs (pleural effusion), congestion and swelling of the liver. When not treated, acute pulmonary edema can be fatal. In some cases it may be fatal even if you receive treatment. This term paper will talk about the symptoms and treatment options for pulmonary edema. PULMONARY EDEMA3

Pulmonary Edema
Pulmonary edema is a condition caused by excess fluid in the lungs. This fluid collects in the numerous air sacs in the lungs, making it difficult to breathe. In most cases, heart problems cause pulmonary edema. Fluid can accumulate for other reasons, including pneumonia, exposure to certain toxins and medications, and exercising or living at...
