Prompt removal from the source of carbon monoxide and high-flow oxygen are essential. Once carbon monoxide exposure is confirmed, the top priority is to take the person out of the CO-containing environment and ensure they receive 100% oxygen to speed up the replacement of carboxyhemoglobin with oxyhemoglobin. In flight, this means arranging rapid evacuation to fresh air and getting the patient to medical care as soon as possible. Hyperbaric oxygen therapy may be considered if there are significant neurological symptoms, loss of consciousness, severe CO exposure, or pregnancy, with the therapy typically pursued after landing and stabilization in a facility equipped for it.

Ventilating with room air would not rapidly clear CO or correct hypoxia, and continuing the flight would keep the exposure ongoing and dangerous. Ignoring the problem obviously fails to address the life-threatening effects of CO poisoning.
