Can anyone explain to me the pathological relationship between atelectasis and pneumonia? I understand the concepts of atelectasis and pneumonia, but I do not fully understand how atelectasis leads to pneumonia. If the patho is too lengthy, reference to a good website would be helpful. Thanks.

you ought to be able to Google lung problems and get a scientific answer, but the REAL answer is that pneumonia is an infection. Infections cause fluid buildup (drainage) and inflammation. These "clog up" the alveoli, just like a sponge that is completely soaked. Fluid replaces air. The lungs can't expand, so they collapse.

In a none-too-lengthy nutshell (in plain english), think of it this way:
Atelectasis most commonly occurs when a person is underventilating her lungs (breathing too shallow) but can also occur in obstruction (ie mucus plug, tumor, etc.)... This eventually leads to the 'collapse/closure' of the lung 'space' that isnt being 'used/ventilated'.
NOW...the area that is 'collapsed' is at a greater risk for developing a pneumonia/infection because the lung's normal mechanisms for 'cleaning itself' are compromised (mucocilliary activity, ventilation, etc.).
The air we breath is full of foreign material (bacteria, etc.) that can cause pneumonia. If this air/material becomes 'stagnant' (for lack of a proper mediacl term) due to atelectasis, it puts the patient at a BIG risk for developing an infection because this 'stagnant' material can 'fester' (again, for lack of a good medical term) and lead to a pneumonia.
Ummm.. does that help???
Thanks for the responses. Much help.

Tha't a great explanation thanks too!

The tricky part, though, is that you can and will get a low grade temp with atelectasis. I think it might even be the #1 cause of post op fever?
