The relevance of the study is due to the widespread use of smoking among young people, which determines the risks of developing various pathologies, in particular,
diseases of the external respiratory system. Combined with climatic stresses typical of the northern region of Russia, nicotine addiction can provoke significant health disorders. The aim of the study was to investigate gas exchange indices in young people under the influence of natural environmental factors (cold) and additional artificial load (tobacco smoking). The MetaMax 3B system was used to assess pulmonary ventilation and gas exchange. The study involved 50 young people aged 18–24 years divided into 2 groups — smokers (24 people) and non-smokers (26 people). The study was conducted during the winter period of the year. The results of the study showed that young northerners are characterised by high values of oxygen consumption and minute volume of respiration, as well as a decrease in the efficiency of gas exchange processes relative to normalised values. In the group of non-smoking young men a more efficient oxygenation process was registered due to higher partial pressure of oxygen in alveoli and oxygen utilisation coefficient, which indicates cost-effective oxygen saturation of blood and subsequent nourishment of body tissues. In the group of young smokers against the background of alveolar hyperventilation, more significant values of ventilation equivalent in oxygen consumption and carbon dioxide release, a higher concentration of O2 in the final portion of exhaled air was observed. This process may indicate the limitation of tissue respiration at the expense
of preserving a certain oxygen reserve for levelling the risks of possible nicotine poisoning.
