This represents one form of this type of lung damage. Name the other types, and what their respective etiologies are. The acini are uniformly damaged and dilated, from the respiratory bronchiole to the terminal acinus. Paraseptal emphysema, in which the proximal airway is normal and only the distal acinus is affected. Greatest in the apices subpleurally, and along connective tissue septa.
Etiology is idiopathic.
Irregular emphysema, in which acinus is irregularly involved, and process is associated with scarring. The acute process is acute bronchopneumonia. With pancreatitis the patient is already ill, is probably not inspiring deeply, and is a set up for hospital acquired pneumonia. The most common organism for community acquired pneumonias is Streptococcus pneumoniae.
