Aspiration pneumonia develops after inhalation of oropharyngeal secretions and colonized organisms. Although organisms frequently implicated in CAP, such as Haemophilus influenzae and Streptococcus pneumoniae, can colonize the nasopharynx and oropharynx and their aspiration can contribute to the development of CAP, the term aspiration pneumonia refers specifically to the development of an infectious infiltrate in patients who are at increased risk f oropharyngeal aspiration. Associated risk factors include the following:
Alcohol use disorder
Altered mental status
Anatomical abnormalities, congenital or acquired
Gastroesophageal reflux disease
