Answer

Answer

There are four types of aspiration syndromes. Aspiration of gastric acid causes a chemical pneumonitis which has also been called Mendelson syndrome. [1] Aspiration of bacteria from oral and pharyngeal areas causes aspiration pneumonia. Aspiration of oil (eg, mineral oil or vegetable oil) causes exogenous lipoid pneumonia, an unusual form of pneumonia. Aspiration of a foreign body may cause an acute respiratory emergency and, in some cases, may predispose the patient to bacterial pneumonia. The pathophysiology, clinical presentation, treatment, and complications of each of these entities are different. [2]
