In: Murray and Nadel's Textbook of Respiratory Medicine. Viruses such as the hantavirus and dengue virus can cause pulmonary edema. Blood transfusions may cause fluid overload in the left ventricle, leading to pulmonary edema. The damage allows fluid to enter the lungs. Smoke from a fire contains chemicals that damage the membrane between the air sacs and the capillaries. A type of pulmonary edema called neurogenic pulmonary edema can occur after a head injury, seizure or brain surgery. Nervous system conditions or surgeries. With treatment, most people with this type of pulmonary edema recover in about 24 hours. A blocked upper airway causes negative pressure in the lungs from trying to breathe through the blockage. Inhaling water causes fluid buildup in the lungs. But people who live at high altitudes can get HAPE with no elevation change if they have a respiratory illness. High-altitude pulmonary edema (HAPE) generally occurs in those who don't take the days or weeks needed to become used to the elevation. Pulmonary edema has been seen in mountain climbers, skiers, hikers and other people who travel to high elevations, usually above 8,000 feet (about 2,400 meters). Inhaling toxins or breathing in some stomach contents when vomiting (aspiration) causes intense irritation of the small airways and air sacs, resulting in fluid buildup. A blood clot moving from the blood vessels in the legs to the lungs can cause pulmonary edema. Blood clot in the lungs (pulmonary embolism).Many drugs - ranging from aspirin to illegal drugs such as heroin and cocaine - are known to cause pulmonary edema. Many conditions can cause acute respiratory distress syndrome (ARDS), including severe injury (trauma), widespread infection (sepsis), pneumonia and severe bleeding. This serious disorder occurs when the lungs suddenly fill with fluid. Acute respiratory distress syndrome (ARDS).Pulmonary edema that is not caused by increased pressures in the heart is called noncardiogenic pulmonary edema.Ĭauses of noncardiogenic pulmonary edema include: Non-heart-related (noncardiogenic) pulmonary edema Thyroid disease and a buildup of iron (hemochromatosis) or protein (amyloidosis) also may contribute to heart failure and cause pulmonary edema. High blood pressure due to narrowed kidney arteries (renal artery stenosis) or fluid buildup due to kidney disease can cause pulmonary edema. Inflammation of the heart muscle (myocarditis), heart problems present at birth (congenital heart defects) and irregular heart rhythms (arrhythmias) also may cause pulmonary edema. Untreated or uncontrolled high blood pressure can enlarge the heart. A valve leak that develops suddenly might cause sudden and severe pulmonary edema. Narrowing (stenosis) of the aortic or mitral heart valves or a valve that leaks or doesn't close properly affects blood flow into the heart. When the left ventricle can't keep up with the demands that are placed on it, fluid backs up into the lungs. Then the heart might not be able to work harder when needed, such as during exercise or with an infection or a rise in blood pressure. With cardiomyopathy, the heart must pump harder, and pressures rise. A damaged heart muscle can no longer pump as well as it should. The clot blocks blood flow and damages part of the heart muscle, resulting in a heart attack. Sometimes, a blood clot forms in one of these narrowed arteries. A slow narrowing of the coronary arteries can weaken the left ventricle. Over time, the arteries that supply blood to the heart muscle can become narrow from fatty deposits (plaques). Medical conditions that can cause heart failure and lead to pulmonary edema include:Ĭoronary artery disease. The increased pressure pushes fluid through the blood vessel walls into the air sacs. When a diseased or overworked left lower heart chamber (left ventricle) can't pump out enough of the blood it gets from the lungs, pressures in the heart go up. Heart-related (cardiogenic) pulmonary edemaĬardiogenic pulmonary edema is caused by increased pressures in the heart.
