COPD Flashcards
Chronic obstructive pulmonary disease is any disease resulting from (2 elements):
Increased airway resistance
Decreased lung or chest wall elastic recoil
Name four diseases included in COPD
Emphysema Bronchiolitis Asthma Chronic Bronchitis (extra: Bronchiectasis)
What is the name of the condition characterized by abnormal and permanent enlargement of airspace with destruction of alveolar wall without fibrosis?
Emphysema
In emphysema, the digestion of lung occurs as an imbalance of which proteins?
Protease and antiprotease
Protease is released by what?
Dying neutrophils and macrophages
What is the main cause of emphysema
Cigarette smoking
What are the effects of cigarette smoking, with respect to emphysema?
Increase number of neutrophils in the lungs
Delay neutrophils transit to other organs
Increase neutrophil elastase release
Increase number of alveolar macrophages
What are the three types of emphysema?
Centrilobular (proximal acinar)
Panlobular (panacinar)
Paraseptal (distal acinar)
Patchy, black holes that are more severe at the apex of the lung is a sign of what?
Centrilobular emphysema
Yellowish coloration at the bottom of the lung is a sign of what?
Panlobular emphysema
Uncommon rupture of the pleural at the apex of lung is a sign of what?
Paraseptal emphysema
What is bronchiolitis (small airway disease)?
Inflammation of the bronchioles
[Mural chronic inflammation
Mural fibrosis
Epithelial goblet cell hyperplasia and luminal mucus accumulation] is a sign of what?
Bronchiolitis
What is the clinical evidence for chronic bronchitis?
Expectoration of mucous on most days for at least three consecutive months for at least two years
What is bronchiectasis?
Irreversible dilatation of a portion of the bronchial tree
