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

Both also had high readings of carboxyhaemoglobin - carbon monoxide.
The AAIB report says: "Toxicology tests on the blood of the passenger showed a carboxyhaemoglobin (COHb) saturation level of 58%."
The AAIB report says: "Toxicology tests on the blood of the passenger [Sala] showed a carboxyhaemoglobin (COHb) saturation level of 58%."
A special bulletin from Britain's Air Accident Investigation Branch said toxicology tests on his blood had shown that Sala had a saturation level of 58% of carboxyhaemoglobin (COHb), a mixture of carbon monoxide (CO) and haemoglobin.
Capillary blood samples were drawn at the start of the test and 7 min post administration of the CO dose for determination of the percentage of bound carboxyhaemoglobin (%HbCO).
Carboxyhaemoglobin levels and their determinants in older British men.
Haemoglobin has greater affinity for CO than oxygen; hence, CO binds with haemoglobin to form a relatively stable complex called carboxyhaemoglobin (COHb).

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).12-14 There is not enough evidence to prove the effect of smoking on hearing loss, especially its combined effect with excess noise.15,16 The current study was planned to assess the simultaneous effect of occupational noise exposure and smoking on hearing loss in refractory's factory workers.
