[Smoking and carbon monoxide consumption (author's transl)]. 1980

D Vanuxem, and C Guillot, and C Grimaud

Among 2,069 patients subjected to pulmonary function tests, 20% were smokers with a mean oxyhemoglobin (HbCO) level of 5.2%. Similar values for HbCO (2.4%) were found in non-smokers and ex-smokers. A positive correlation was observed between daily tobacco consumption and HbCO level, i.e. HbCO = 0.123 (g/day) + 3.433. For a similar consumption (16 g/day), smokers who inhaled the smoke had a significantly higher level of HbCO than smokers who did not (5.8 vs. 4.7%). The interval separating the time when the last cigarette was smoked from HbCO measurement is of utmost importance: for a similar tobacco consumption (10 g/day) HbCO ranged from 6.5 +/- 0.5% when the interval was 1 h to 4.6 +/- 0.3% when it was 3 h (p < 0.005). In some cases, there were discrepancies between the number of cigarettes smoked as indicated by the subjects and the measured levels of HbCO. Possible inhalation of exogenous CO from other sources than smoking or increased production of endogenous CO could account for these differences.

D002248	Carbon Monoxide	Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)	Monoxide, Carbon
D006454	Hemoglobins	The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements.
