In what manner would O₂ therapy induce worsening mismatch and thus a further elevation in CO₂ in a chronically hypercapnic patient?

Question

Quizplus · Accepted Answer

Oxygen breathing causes more blood flow to be directed to poorly ventilated alveoli, which takes blood flow away from well-ventilated alveoli. The key point is that when already under-ventilated alveoli receive additional blood flow, blood PCO₂ rises further. These events can occur without a fall in overall minute ventilation.
