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
Being less alert due to medicines, illness, or other reasons
Drinking large amounts of alcohol
Medicine to put you into a deep sleep for surgery (
- Old age
- Poor gag reflex in people who are not alert (unconscious or semi-conscious) after a stroke or brain injury
Problems with swallowing
Bluish discoloration of the skincaused by lack of oxygen
- Chest pain
- Coughing up foul-smelling, greenish or dark phlegm (sputum) or phlegm that has pus or blood
Fatigue Fever Shortness of breath Wheezing Breath odor Excessive sweating
- Problems swallowing
Signs and tests
A physical examination may reveal:
Crackling sounds in the lungs
Rapid pulse(fast heartbeat)
Decreased mental awareness
The following tests may also help diagnose this condition:
Arterial blood gas Blood culture Bronchoscopy Chest x-ray
- Complete blood count (
CBC) CT scanof the chest Sputum culture
- Swallowing tests
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.
- Spread of infection to the bloodstream (
- Spread of infection to other areas of the body
- Respiratory failure
