Concentration of light hydrocarbons in exhaled air depending on metabolic syndrome risk factors

The effect of metabolic syndrome risk factors on the content of light hydrocarbons (C 2 -C 3 ) in exhaled air has been studied with the participation of students of Novosibirsk State Medical University. Gas chromatography was performed in an EKHO-EW-FID chromatograph with a short multichannel column. The study revealed sex-related differences between the concentrations of light hydrocarbons in exhaled air. In addition, some factors, such as smoking and type 2 diabetes mellitus in relatives, affect the content of C 2 -C 3 compounds in exhaled air of women only. However, overweight is correlated with the content of acetone (C 3 ) in exhaled air only in men. Thus, the metabolic changes caused by the presence of age-specific metabolic syndrome risk factors lead to the changes in the gas composition of exhaled air and can be detected and used for early diagnosis.
