Hospital-acquired pneumonia is an infection of the lungs that occurs during a hospital stay.
Nosocomial pneumonia; Ventilator-associated pneumonia; Health-care associated pneumonia
Causes, incidence, and risk factors
Hospital-acquired pneumonia tends to be more serious than other lung infections, because:
- Patients in the hospital are often sicker and unable to fight off germs.
- The types of germs present in a hospital are often more dangerous than those encountered in the community.
Hospital-acquired pneumonia occurs more often in patients who are using a respirator machine (also called a ventilator) to help them breathe. When pneumonia occurs in a patient who is on a ventilator, it is known as ventilator-associated pneumonia.
Risk factors for hospital-acquired pneumonia include:
- Being on a breathing machine
- Breathing saliva or food into the lungs (
- Chest surgery
Immunosuppression(immune system does not work well)
- Long-term (chronic) lung disease
- Not being fully alert
- Older age
- Recent illness
