cyanmethemoglobin

hemoglobinometry

 [he″mo-glo-bĭ-nom´ĕ-tre]
measurement of the hemoglobin content of the blood, usually with a hemoglobinometer after the hemoglobin has been converted to cyanmethemoglobin.

cy·an·met·he·mo·glo·bin

(sī'an-met-hē'mō-glō'bin),
A relatively nontoxic compound of cyanide with methemoglobin, which is formed when methylene blue is administered in cases of cyanide poisoning.

cyanmethemoglobin

/cy·an·met·he·mo·glo·bin/ (si″an-met-he´mo-glo″bin) a tightly bound complex of methemoglobin with the cyanide ion; the pigment most widely used in hemoglobinometry.

cy·an·met·he·mo·glo·bin

(sī'an-met-hē'mŏ-glō-bin)
A relatively nontoxic compound of cyanide with methemoglobin, which is formed when methylene blue is administered in cases of cyanide poisoning.
Synonym(s): cyanmethaemoglobin.

cyanmethemoglobin

a compound formed by combination of hydrocyanic acid with methemoglobin. It is formed when methylene blue is administered as an antidote in cyanide poisoning. In laboratory methods, hemoglobin is converted to cyanmethemoglobin and measured spectrophotometrically.
