What it is

Pulmonary fibrosis involves thick, stiff, or scarred lung tissue.[1,2]

Why it matters

Scarring can make it harder for oxygen to pass from air sacs into blood.[1,2]

What it affects

  • Fibrosis context often uses imaging and lung function testing.[1,2]

Interpretation traps

  • Pulmonary fibrosis is not inferred from cough or shortness of breath alone.[1,2]
