A 68-year-old man with stable COPD and no signs of cor pulmonale is seen in clinic and has a resting arterial blood gas on room air. Which result is an indication for long-term oxygen therapy?
Explanation
Answer: B. PaO₂ 52 mmHg
Long-term oxygen therapy in COPD is indicated when SaO₂ is ≤88% or PaO₂ is ≤55 mmHg, and it improves mortality.

Why the others are wrong
A62 mmHg is above the course material's threshold of PaO₂ ≤55 mmHg.
C68 mmHg is above the course material's threshold of PaO₂ ≤55 mmHg.
D75 mmHg is well above the course material's threshold of PaO₂ ≤55 mmHg.
