In what manner would oxygen therapy induce worsening $\dot { V }$ / $\dot { Q }$ mismatch and thus a further elevation in CO₂ in a chronically hypercapnic patient?

Question

Quizplus · Accepted Answer

Oxygen therapy can worsen $\dot { V }$ / $\dot { Q }$ mismatch in chronically hypercapnic patients by improving blood flow to poorly ventilated alveoli, which can paradoxically decrease overall oxygenation by increasing perfusion to areas of the lung that are not adequately ventilated.
