What impact will the administration of a high FIO₂ likely have on a patient with chronic hypercapnia and hypoxemia?
A) peripheral chemoreceptors may be suppressed by the excess oxygen being administered and ventilation would be depressed
B) central chemoreceptors may be suppressed by the high O₂ being administered and ventilation would be depressed
C) peripheral chemoreceptors may be suppressed due to the low H+ and ventilation would be depressed
D) both central and peripheral chemoreceptors would respond by triggering oxygen induced hyperventilation

In patients with chronic hypercapnia, their respiratory drive is often more dependent on hypoxemia (low oxygen levels) rather than hypercapnia (high carbon dioxide levels). Administering high levels of oxygen can suppress the peripheral chemoreceptors, which are sensitive to oxygen levels, leading to a decrease in ventilation and potentially worsening hypercapnia.
