Aspiration may occur under several circumstances. 1  Before the swallowing reflex is triggered, when the airway has not elevated or closed. 2  During the swallowing if the laryngeal valves are not functioning adequately. 3  After the swallow when the larynx lowers and opens for inhalation.
When these things get into your lungs, they can cause damage, blockage and bacterial, viral or fungal infections. In turn, potentially causing aspiration pneumonia. And the more acidic the material, the more severe your lung injury. The symptoms of aspiration pneumonia depend on what you inhaled and how much.
