A condition characterized by fluid accumulation in the lungs caused by back pressure in the lung veins.
Fluid overload is a common cause in infants.
Fluid backs up into the veins of the lungs. This interferes with the exchange of oxygen and carbon dioxide in the alveoli. In many cases, this condition can not be prevented. The risk can be reduced by prompt treatment of cardiac disorders. A chest X-ray may show fluid in the lung space.
