WebA relatively nontoxic compound of cyanide with methemoglobin, which is formed when methylene blue is administered in cases of cyanide poisoning. Synonym (s): … WebThen hemoglobin (and methemoglobin and carboxyhemoglobin) is converted to cyanmethemoglobin (sulfhemoglobin is not converted). The absorbance of light at 540 nm is then measured. • Smokers have higher than usual carboxyhemoglobin. Carboxyhemoglobin takes longer to be converted to cyanmethemoglobin.
