A spirographic study of 80 students from 1-3 courses of Surgut State Pedagogical University at the age of 18-20 years old, born and residing in the North has been carried out. The aim of the work was to study the peculiarities of the respiratory system of the university students. Measurement of respiratory function was carried out by means of Program Apparatus Complex 'Spiro-Spectrum'. Results were analyzed by standard methods of mathematical statistics. All surveyed belonged to 1 and 2 health groups. Students with chronic and acute diseases of the respiratory system were excluded from surveyed group. It was found out that needed respiratory minute volume at rest in students-smokers was achieved by increase in respiratory rate and not by respiratory volume which was more energy-consuming. Reduce of maximum expiratory flow from 50 % and 75 % of forced vital capacity (FVC) and forced expiratory flow rate from 25-75 % FVC in students-smokers were reflection of respiratory failure and a high risk of obstructive disorders development. Lower rates of maximum breathing capacity in smokers compared to proper values show decrease in the frontier of external breathing.
