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 due to the low H+ and ventilation would be depressed B) peripheral chemoreceptors may be suppressed by the excess oxygen being administered and ventilation would be depressed C) central chemoreceptors may be suppressed by the high O₂ being administered and ventilation would be depressed D) both central and peripheral chemoreceptors would respond by triggering oxygen induced hyperventilation

Question

Quizplus · Accepted Answer

Peripheral chemoreceptors can be suppressed by the excess oxygen being administered, leading to depressed ventilation. This is because in patients with chronic hypercapnia, the body adjusts to higher CO2 levels, making oxygen levels a more significant driver of respiration. Administering high levels of oxygen can reduce the stimulus for breathing in these patients.
