Question 1

Can COPD be completely cured?

Accepted Answer

COPD is a chronic disease that causes irreversible damage to the lungs and cannot be completely cured. However, with early diagnosis and appropriate treatment, disease progression can be slowed, symptoms can be controlled, and quality of life can be significantly improved.

Question 2

Does COPD only occur in smokers?

Accepted Answer

No. Although smoking is the most important risk factor for COPD, it can also develop in people who have never smoked. Long-term air pollution, occupational exposures, genetic factors (alpha-1 antitrypsin deficiency), and childhood respiratory infections can also cause COPD development.

Question 3

When is oxygen therapy needed for COPD?

Accepted Answer

Oxygen therapy is recommended when blood oxygen levels drop below a certain value (usually SpO2 <88% or PaO2 <55 mmHg). Long-term oxygen therapy (LTOT) can extend life span and improve quality of life in severe COPD patients.
