"Carbon monoxide (CO) poisoning may be the most common cause of fatal poisonings worldwide. The majority of poisonings occur in the Fall and Winter. It is that time of year when heaters that have lain dormant all summer are flicked on, sometimes in enclosed areas, introducing CO fumes into homes. The pathophysiology is complex, and not fully understood, but all ED physicians should be aware of the signs and symptoms of CO toxicity, and know how to treat it."
