Summary Introduction
Concept introduction: Carbon monoxide (CO) is a colorless, odorless gas that is released when the organic material burns. Carbon monoxide poisoning is the most common type of fatal inhalation poisoning in the United States and worldwide. When CO is present in the body, the blood holds more less oxygen and releases of little of what it does hold to tissues.
