Types of Pneumonia
Hospital-Acquired PneumoniaA second pneumonia type is hospital-acquired pneumonia. People get this type while in the hospital for another illness. A person is at higher risk for transmitting hospital-acquired pneumonia if he or she is on a mechanical ventilator (a machine that helps you breathe).
Hospital-acquired pneumonia tends to be more serious than the community-acquired type. This is because the person is already sick. Also, hospitals tend to have more germs that are resistant to antibiotics -- a common pneumonia treatment.
Most cases of hospital-acquired pneumonia are caused by bacteria. Viruses or fungi are less likely to cause the condition, except in people with a weakened immune system.
Another name for hospital-acquired pneumonia is nosocomial pneumonia.
Healthcare-Associated PneumoniaA third type of pneumonia is healthcare-associated pneumonia. This is diagnosed when a person transmits pneumonia in other healthcare settings, such as nursing homes, dialysis centers, and outpatient clinics.
Other Types of PneumoniaYou might hear about other pneumonia types. Some of these include:
- Aspiration pneumonia
- Typical and atypical pneumonia
- Walking pneumonia
- Double pneumonia.
This type occurs when you accidentally inhale food, liquid, vomit, or saliva from your mouth into your lungs. This usually happens when something disturbs your normal gag reflex, such as a brain injury, swallowing problem, or excessive use of alcohol or drugs. Aspiration pneumonia can cause pus to form in a cavity in the lung. This is called a lung abscess.
