What are common signs of carbon monoxide exposure in the flight deck and the actions to take?

Carbon monoxide exposure in the cockpit presents with early signs such as headache, dizziness, and nausea. These symptoms occur because carbon monoxide binds strongly to hemoglobin, reducing the amount of oxygen delivered to the brain and other tissues. The best response is to get to fresh air and reduce exposure quickly: descend to a lower altitude or move to an air source with more oxygen, open vents to improve ventilation, and seek medical evaluation as soon as possible. If available, use supplemental oxygen to help counter the reduced oxygen delivery while you arrange for medical assessment after landing. Sneezing and coughing aren’t typical signs of CO exposure, ignoring the symptoms isn’t safe, and simply continuing isn’t appropriate. An elevated heart rate with climbing isn’t a remedy and can worsen the situation, while visual halos can occur with CO but the priority action remains to secure fresh air and reduce exposure through descent and ventilation, followed by medical evaluation.
