What Are The Most Common Lung Diseases?

Pulmonary Edema

Pulmonary edema is a lung condition where excess fluid accumulates in the air sacs or alveoli, causing problems with the function and structure of the organs. Pulmonary edema can be caused by problems with heart structure or function, or it can be caused by nervous system conditions, high altitudes, acute respiratory distress syndrome, adverse drug reaction, pulmonary embolism, smoke inhalation, near drowning, infections, and toxin exposure. Symptoms of pulmonary edema include breathlessness, wheezing, clammy skin, blue-tinted lips, palpitations, rapid weight gain, lower extremity swelling, fatigue, anxiety, productive cough, fever, chest discomfort, headaches, difficulty with exercise, and shortness of breath upon exertion or lying down. Pulmonary edema is diagnosed with the use of a physical examination, pulse oximetry, blood tests, echocardiogram, chest x-rays, cardiac catheterization, and electrocardiogram. Treatment for pulmonary edema may include administration of supplemental oxygen, diuretic medications, morphine, blood pressure medications, and in rare cases, therapy in a hyperbaric chamber.
