Analysis of blood for asphyxiant toxicants. Carbon monoxide and hydrogen cyanide Ingestion-build-264231 concept application1 Scope This International Standard details analytical methods suitable for analysing the two primary toxic combustion gases, carbon monoxide (CO) and hydrogen cyanide (HCN), in blood samples collected from fire casualties. In blood, CO is measured as carboxyhaemoglobin (COHb) and HCN as cyanide ion (CN). Although numerous methods are reported in the literature for performing blood COHb and CN analyses, the analytical methods included herein are based
