Carbon monoxide and carboxyhemoglobin contents in exhaled air and blood pressure levels with diff erent nicotine delivery pathways

Abstract

Aim. To assess the content of CO and COHb in exhaled air and the level of blood pressure (BP) in the working-age population of Yuzhno-Sakhalinsk when using various means of nicotine delivery.Materials and methods. The study participants (n = 503) were surveyed using a questionnaire. The BP and oxygen saturation parameters were assessed. The content of CO and COHb content in exhaled air was measured using a smokerlyzer. Statistical processing was performed using nonparametric methods.Results. The study group was dominated by males (58.3%). A high incidence of smoking was observed among females, with up to 42% in the general group and 48.8% in the group of consumers of alternative nicotine delivery systems (ANDS). A correlation between the content of CO and COHb and the smoking experience of more than 10 years was established, regardless of the means of nicotine delivery. Arterial hypertension was registered among 39.8% of the surveyed participants, with a higher frequency in cigarette smokers (28.8%, p = 0.02). This was associated with a greater proportion of individuals (62%) with a long smoking experience of more than 10 years (p = 0.003). A weak direct correlation was established between an increase in blood pressure and the content of CO and COHb (p < 0.001).Conclusion. The share of females as active consumers of tobacco products has grown, particularly in the form of ANDS. Among smokers, the average high level of CO and COHb prevails, which correlates with the smoking experience of more than 10 years and does not depend on the means of nicotine delivery. A direct relationship between the intensity of smoking and the risk of hypertension was established.
