Pneumonia is a breathing condition in which there is swelling or an infection of the lungs or large airways.
Aspiration pneumonia occurs when food, saliva, liquids, or vomit is breathed into the lungs or airways leading to the lungs.
Anaerobic pneumonia; Aspiration of vomitus; Necrotizing pneumonia; Aspiration pneumonitis
Causes, incidence, and risk factors
The type of bacteria that caused the pneumonia depends on:
Where you live (at home or in a long-term nursing facility, for example)
Whether you were recently hospitalized
Recent antibiotic use
Risk factors for aspiration or breathing in of foreign material into the lungs are:
Signs and tests
A physical examination may reveal:
The following tests may also help diagnose this condition:
Some people may need to be hospitalized. Treatment depends on how severe the pneumonia is. Sometimes a ventilator (breathing machine) is needed to support breathing.
You will likely receive antibiotics.
You may need to have your swallowing function tested. Persons who have trouble swallowing may need to use other feeding methods to reduce the risk of aspiration.
Outcome depends on:
Health of the person before getting pneumonia
Type of bacteria causing the pneumonia
How much of the lungs are involved
More severe infections may result in long-term damage to the lungs.
- Lung abscess
- Spread of infection to the bloodstream (bacteremia)
- Spread of infection to other areas of the body
- Respiratory failure
