carboxyhaemoglobin

(kɑːˌbɒksɪˌhiːməʊˈɡləʊbɪn; -ˌhɛm-) or

carboxyhemoglobin

n
(Biochemistry) haemoglobin coordinated with carbon monoxide, formed as a result of carbon monoxide poisoning. As carbon monoxide is bound in preference to oxygen, tissues are deprived of oxygen

19,20] It is known that a high level of carboxyhaemoglobin is found in smokers and that it persists longer than was previously thought after each cigarette, resulting in chronic hypercarboxyhaemoglobinaemia, the influence of which on the foetus, and particularly on its birth weight has been proved.
Carbon monoxide is a poisonous gas which binds easily to haemoglobin to form carboxyhaemoglobin, which smoking increases; (21) this results in less oxygen in the blood causing tissue hypoxia.
Smoking causes hearing loss, most possibly by affecting the blood flow of the cochlea and also reducing the access of the auditory cells to oxygen as a result of increased blood carboxyhaemoglobin (COHb).
The breath CO analyser is an instrument which calculates the amount of carbon monoxide in a single exhaled breath, automatically calculates the percentage of carboxyhaemoglobin in the blood of the mother and estimates the carboxyhaemoglobin in the baby's blood.
Dr Kazim explained that after carbon monoxide is breathed in, it enters your bloodstream and attaches to haemoglobin (the part of red blood cells that carry oxygen around your body), to form carboxyhaemoglobin.
Capillary blood samples were obtained at the start of the test as well as at seven minutes post administration of the CO dose for determination of the percentage of bound carboxyhaemoglobin (%HbCO).
CO poisoning could not be excluded because of laboratory and transit errors, preventing a carboxyhaemoglobin level from being obtained.
Kevin, who was diagnosed as morbidly obese in May 2011, had a carboxyhaemoglobin level of 59% against a fatal level of 50%.
According to forensic experts, a lethal dose of carboxyhaemoglobin was found in their blood.
Identifying these optical fingerprints enables us to extract the concentration of glucose or carboxyhaemoglobin.
