Causes
Only air should enter the airways of the lungs. Sometimes foods, liquids, or vomited stomach contents may accidentally get into these airways and inhaled into the lungs. This is called aspiration. It results in irritation and swelling in the lungs. This makes it possible for an infection to develop.
Risk Factors
Most people can cough to prevent aspiration, but people with certain health problems may not be able to do so. Things that may raise the risk of aspiration pneumonia are:
- Being less alert due to alcohol intake, seizures, stroke, or other conditions
- Problems swallowing due to poor teeth or a history of Parkinson disease, amyotrophic lateral sclerosis (ALS), stroke, or other conditions
- A history of gastroesophageal reflux disease (GERD)
Symptoms
Symptoms of aspiration pneumonia may be:
- Increased cough
- Increased sputum
- Fever
- Lack of energy
- Chest pain
- A change in mental status
- Problems breathing
- Weight loss
Diagnosis
The doctor will ask about symptoms and past health. A physical exam will be done.
Tests may be done to look for signs of infection. This may include:
- Blood tests
- A sputum test
Pictures may be taken of the lungs. This can be done with a chest x-ray. The ability to swallow may also be tested. This can be done with a barium swallow.
Treatment
Emergency care may be needed. Antibiotics will be given to treat the infection. It may be given through an IV or by mouth.
Some people with severe symptoms may need mechanical ventilation to help with breathing.
Prevention
The risk of this problem may be lowered by:
- Managing chronic health problems
- Following fasting instructions before a surgery
