- A fairly stable union of carbon monoxide with hemoglobin. The formation of c. prevents the normal transfer of carbon dioxide and oxygen during the circulation of blood; thus, increasing levels of c. result in various degrees of asphyxiation, including death. SYN: carbon monoxide hemoglobin, carbonmonoxy myoglobin.
