Popis:	Two hundred and twenty-seven healthy medical students were divided into the main (112 smokers) and the control (115 non-smokers) groups. Depending on the risk of COPD occurrence (smoking index > 140) the smokers were divided into the risk-positive (34.5 % of the smokers) and the risk-negative (65.5 %) subgroups. Smoking duration, smoking psychological dependence, need in smoking under an emotional exertion and a habit of nicotine were higher in the risk-positive smokers. The vital capacity, the inspiratory and expiratory reserve volumes, and the peak expiratory flow rate were higher in smokers as a result of adaptation of the respiratory system to smoking, in particular to the negative influence of carbon monoxide. This adaptation is aimed to the SpO2 restoration. But this parameter was lower in smokers, especially in the risk-positive subgroup. Thus, the functional adaptation of the respiratory system to the severe smoking in students with the risk of COPD is failed.
