What is the initial action in emergency treatment for carbon monoxide poisoning?

• A. Ventilate only after calling for medical help.
• B. Shut off potential sources of CO and ventilate.
• C. Immediately administer antidote.
• D. Ventilate after contacting medical help.

Answer: (B)

The first move is to remove the person from exposure and start providing oxygen. Shut off the source of carbon monoxide to stop further inhalation, then ventilate to deliver breathable air and raise the amount of oxygen in the lungs. CO binds strongly to hemoglobin, forming carboxyhemoglobin and starving tissues of oxygen, so stopping the exposure and increasing oxygen delivery are both essential right away. There isn’t an antidote for CO poisoning, so the emphasis is on stopping exposure and rapid oxygenation. If you can do so safely, move the person to fresh air and call for emergency help while you provide high-flow oxygen (for example, a non-rebreather mask) or assist ventilation if trained.
