ASSESSMENT OF CHANGES IN THE LEVEL OF DIASTOLIC BLOOD PRESSURE UNDER CONDITIONS OF ADDITIONAL RESPIRATORY RESPIRATION
Today, the task of clarifying the patterns of multi-connected regulation of respiratory and hemodynamic parameters under various conditions of the body remains very urgent. The aim of this work was to assess the changes in the level of diastolic blood pressure and indicators of the respiratory system when presented with different values of resistive respiratory loads. The study was conducted on 29 healthy men and women aged 18 to 26 years. External resistance to breathing was included during inhalation in four gradations: 11; 28; 54; 76 cm water st. / l / s using a device that allows remote metering of resistive load; The time (sec) of its presentation was used as a measure of the intensity of the action of the load. The conditioned respiratory reflex was developed as a short-delayed one with a period of isolated action of the conditioned signal of 10 seconds. Diastolic blood pressure was monitored during each cardiac cycle on the basis of our developed method and device (inventor's certificates for inventions No. 1593625 and No. 1673044). The results of the study showed that the implementation of resistive respiratory loads before training is characterized by hypoxic-hypercapnic shifts. Additional respiratory resistance of different magnitude causes conjugate changes in diastolic blood pressure and indicators of the respiratory system. Conditioned reflex regulation under the action of resistive loads causes a significant redistribution of blood pressure conjugation mechanisms and parameters of the respiratory system. A close conjugate relationship between the indicators of the implementation of resistive loads in the circulatory system and the central inspiratory mechanism was noted; the statistical relationship was less pronounced in relation to ventilation output and hypoxia level.
