Introduction[edit | edit source]
In pneumonia, microaspiration is the usual pathogenic mechanism, while “aspiration pneumonia” refers to the aspiration of a large amount of oropharyngeal or upper gastrointestinal content moving through the vocal cords and trachea into the lungs.[1]
Risk Factors[edit | edit source]
Include:
- Impaired swallowing (dysphagia, chronic obstructive pulmonary disease, neurological diseases eg stroke or dementia, need of mechanical ventilation),
- Weakened cough reflex (medications, stroke, dementia, impaired consciousness and alcohol).
- Reduced consciousness (acute stroke, head injury, brain lesions, seizures and the effect of some agents that can induce impaired consciousness such as alcohol, drugs, anesthesia or sedatives),
- Greater likelyhood of gastric contents reaching the lung (reflux and tube feeding).[1]
