aspiration pneumonia

is the result of inhalation or aspiration of infected solid or liquid material into the lungs. Large volumes of aspirate cause asphyxia, smaller amounts cause a necrotic or gangrenous pneumonia, in anterior and ventral parts of the lung. There is profound toxemia, cough, gurgling or squeaky rales, and usually an attendant pleurisy producing a friction rub. Called also inhalation pneumonia.
