Flashcards in Chapter 15: Pulmonary Fibrosis Deck (12):
Fibrous thickening and scarring of alveolar septa due
to severe pulmonary injury from lungs continually
exposed to injurious substances such as irritant gases,
many kinds of airborne organic and inorganic
particles, medications, TB, radiation, chemo, etc.
What happens to the lungs in pulmonary fibrosis?
1) Lungs become rigid
2) Diffusion of gases hampered due to increased alveolar septal thickness.
3) Progressive respiratory disability
What can cause pulmonary fibrosis?
1) Collagen diseases (e.g., lupus) that damage connective tissues
3) Pneumoconiosis (injury from inhalation of injurious dust or other material)
lung injury from inhalation of
injurious dust or other particulate material
A progressive nodular pulmonary fibrosis
caused by inhalation of rock dust
A diffuse pulmonary fibrosis caused by
inhalation of asbestos fibers
What are two examples of pneumoconiosis (lung injury from inhaling particles)?
How is pulmonary fibrosis diagnosed?
1) Breathing tests
2) CT scan
3) Lung biopsy
What are the symptoms of pulmonary fibrosis?
Dry cough that does not respond to medications
How is pulmonary fibrosis treated?
1) Reduce disease progression (steroids and immunosuppressants)
2) Lung transplant
True or false: Pulmonary fibrosis is completely reversible.
