Aspiration pneumonia is common among seniors, people with dysphagia, and people with chronic breathing disorders. It can also occur during or following surgery, or subsequent to a sudden trauma. Mortality rates vary greatly and rise with patient age and comorbidities, as well as the total volume of aspirated fluids. Among those with emphysema, it may be as high as 20%. Reducing the risk of aspiration pneumonia can save lives, reduce healthcare expenditures, and prevent health system crowding.
