13 Patients with chronically high pCO2 blood levels breath due to a hypoxic drive. What would happen if they were to breath 100% oxygen?

Respiratory rate would increase in order to exhale the excess CO2

Respiratory rate would slow and eventually breathing would stop

Respiratory rate would increase producing a respiratory alkalosis to buffer their chronic respiratory acidosis
