Pulmonary edema is a serious medical condition. It is caused by a buildup of fluid in the lungs. This excess fluid in the lungs makes it difficult for the lungs to fill with air. This makes it difficult for the body to get the oxygen it needs. A problem with the heart is the most common cause of pulmonary edema. It is important to seek medical care if this condition is suspected. Information about this condition is useful. It allows people to better understand what is occurring within their own body.
Information. When we breathe, air is taken into our lungs. Within the lungs are many small air sacs called alveoli. These air sacs take in oxygen when we breathe. This oxygen is then circulated throughout the body by the blood. Every organ, tissue and cell in our body needs oxygen to function properly. With pulmonary edema, fluid collects in these air sacs impairing their ability to fill with air and take in oxygen. This lack of oxygen leads to the symptoms of pulmonary edema, including difficulty breathing, coughing, wheezing and swelling in the legs and feet. Treatment to decrease the amount of fluid in the lungs can help improve these symptoms.
