Аннотация

The aim of the study was to evaluate the effect of the duration of training on the use of personal respiratory protective equipment on indices of pulmonary gas exchange. Simulation of conditions for the use of personal respiratory protective equipment was carried out at the inspiratory resistance of 40, 60, 70 and 80% Pmmax. The study included 38 healthy male subjects aged 20 to 36 years. According to the results of the study, under the use of personal protective equipment for the respiratory system, preliminary training was shown to be essential. In the subjects without preliminary training, the use of personal protective equipment was followed by a weak change in the nature of the respiratory pattern. After the preliminary training subjects had an adaptive rearrangement of the respiratory pattern, consisted of the decline in breathing movements as the respiratory resistance increased. Preliminary training to the exposure of additional resistance to breathing, altered pulmonary gas exchange and acid-base state of blood. The trained subjects had higher pCO2 blood values and lower values of pO2. They showed a greater deficit of buffer bases of plasma compared to untrained ones. This fact testified the preliminary training for the use of personal respiratory protective equipment (long-term adaptation) changed the gas composition and acid-base state of the blood to be a more economical mode of the discharge of buffer systems. On the basis of the data obtained, the preliminary training for increased respiratory resistance was suggested to be advisable before the using personal respiratory protective equipment.
