Aspiration Pneumonia results when food, drink, vomit, secretions or
other foreign material is inhaled and causes an inflammatory response in
the lungs and bronchial tubes.
Aspiration Pneumonia occurs predominantly in the right lung because its total capacity is greater than that of the left lung .
This term refers of Pneumonia caused by the following bacteria:
Legionella pneumophila, Mycoplasma pneumoniae, and Chlamydophila
Atypical pneumonia is caused by bacteria and does not respond to the normal antibiotics used for treatment.
Bacterial Pneumonia occurs when pneumonia-causing bacteria masses and
multiplies in the lungs. The alveoli become inflamed and pus is
produced, which spreads around the lungs. The bacteria that caused
Bacterial Pneumonia are: streptococcus pneumonia, hemophilus influenza,
legionella pneumophilia and staphylococcus aureus.
Bronchopneumonia is “a descending infection starting around the bronchi
and bronchioles” (Nurse’s dictionary, Twenty-third edition, 2000). The
terminal bronchioles become blocked with exudates and form consolidated
patches. This results in atelectasis.
This means the infection was acquired at home.
With this type of pneumonia the most common cause is
Patients develop features after being in hospital for 24 hours or longer
Infectious agent is often Gram-negative bacteria such as 'Escherichia coli or Klebsiella'
Mycoplasmal Pneumonia: (also known as 'walking pneumonia')
It is similar to bacterial pneumonia, whereby the mycoplasmas proliferate and spread - causing infection (healthscout.com).
Pneumocystis carinii Pneumonia:
Pneumocystis carinii pneumonia is the result of a fungal infection in the lungs caused by the Pneumocystis carinii fungus.
This fungus does not cause illness in healthy individuals, but rather
in those with a weakened immune system. (Health-cares.net, 2005).
Ventilator Associated Pneumonia (VAP):
This type of pneumonia usually occurs two days after a hospitalised
patient has been intubated and been receiving mechanical ventilation.
This is especially a life-threatening infection as patients who require mechanical support are already critically ill.
Viral Pneumonia is believed to be the cause of half of all pneumonias.
The viruses invade the lungs and then multiply- causing inflammation
