Tobacco smoking is one of the important social and educational problems posing a serious threat to the health of young people.

There are many works devoted to the study of the effect of smoking on violations of various functions and systems of the body(V.M. Andreev 2006; Vlasov O.V. 2009; Gerasimenko, N.F., 2008, etc.) .

However, functional changes in the respiratory system while tobacco smoking in young people long before the appearance of symptoms of a disease not been studied, the modern method of spirometry - undervalued.

The aim of the work was to study the effect of tobacco smoking on the health of young people, qualitative and quantitative evaluation of the functional state of the mechanical properties of the lungs ventilation in smokers and non-smoking students.

Analysis of the results showed a high prevalence of smoking among young people, despite the common position of the harm its health. Of the 60 subjects, students of Moscow State Pedagogical University and the world took part in the experiment (and 34devushki 26yunoshey) 37% are smokers. Of these, the high smoking history, age 6 years or more are 36.3%. Duration smoking duration boys on average 5.7 years longer than girls.

Research undertaken as donozologicheeskoe as a criterion for selecting students was the absence of the latter doctors diagnosed diseases of the respiratory system. Among smokers, the vast majority of students (72.7%) identified certain violations of bronchial conductance. A small percentage of smokers and non-respiratory disorders

were mostly girls with little experience of smoking and smoke less than 5 cigarettes a day.

Smokers students of both sexes revealed changes in functional status indicators breathing - a common rate 31.2%, the rest-to-moderate or significant decrease in indicators such as the forced expiratory volume (FVC), the index Tiffno, instantaneous flow rate at the time of expiration 25% (MOS25 (l / s)) and peak (maximum) flow rate (PIC (l / c)), under the test minute volume and maximum ventilation - low lung capacity, and increased respiratory rate per minute.

Thus, the findings suggest the presence of structural and functional changes of the respiratory system in young adults, also upgrading the sympathetic system (hyperventilation), and because the respiratory system is an integral index, decreased levels of health, especially for young smokers.
