Aspiration pneumonia

Also written as aspiration PNA, asp. pneumonia.

Aspiration pneumonia is a lung infection that can develop after food, drink, saliva, or stomach contents enter the airway instead of the food pipe.

Aspiration pneumonia is a lung infection. StatPearls, a peer-reviewed medical reference, defines it as a lung infection resulting from breathing in fluids that carry bacteria — such as secretions from the mouth and throat, small particles of food, or stomach contents — down into the lower airway.

It helps to separate two words that sound similar. "Aspiration" on its own simply means something went toward the airway instead of the food pipe. Aspiration pneumonia is an infection that can follow. The two are not the same term, and doctors also distinguish aspiration pneumonia from aspiration pneumonitis, which StatPearls describes as a non-infectious chemical irritation of the lung from breathing in sterile fluid or stomach contents.

Aspiration pneumonia is diagnosed and treated by physicians. StatPearls notes that some groups have higher risk than others, including older adults, people with swallowing difficulties or neurological conditions such as stroke, Parkinson disease, or dementia, people who are bedridden or have limited mobility, and people with poor oral health.

Speech-language pathologists pay attention to this term because protecting the airway is one of the reasons swallowing is evaluated in the first place. When it appears in notes or conversation, it usually means a team is thinking ahead about prevention — oral care, positioning, how meals are going. It is a general medical term, not a statement about what will happen to any one person. Questions about your own situation are for your doctor and SLP.
