pulmonary oedema

Accumulation of fluid in the lungs, usually as a result of failure of the left side of the heart to pump away, sufficiently quickly, the blood returning from the lungs (left HEART FAILURE). Pulmonary oedema may also be caused by inhalation of irritant gases or to any disorder causing generalized oedema. There is severe breathlessness usually worse when lying flat (ORTHOPNOEA), a productive cough and sometimes blood-tinged sputum. Treatment is with DIURETIC drugs and attention to the cause.
