Effectiveness Application of the Analysis of Arterial Pulsations Registered during Blood Pressure Measurement Using the Oranta-AO Information System in Psychophysiology

Abstract

Introduction: Post-traumatic stress disorders associated with the situation in Ukraine, rapid societal automation and informatization have demanded the development of new, accessible, and highly informative methods for diagnosis, monitoring, prediction, and patient state correction. To study the level of heart and brain rhythm activity at rest and their dynamics during adaptation to changing external conditions. Materials and Methods: A total of 720 individuals of both genders, various ages, and health statuses were examined using the arterial oscillography method. Arterial oscillograms (AOG) were recorded during the measurement of arterial pressure at rest and after the influence of different factors (physical, thermal, multimedia, etc.). AOG analysis was conducted using temporal and spectral methods developed by the authors of the study. Results: The research has shown that in cases of depressive disorders, there is an increase in the activity of the sympathetic-adrenal system, which is manifested by a disruption in the functional ability of all levels of hemodynamic regulation. Some changes in brain rhythm activity have been observed under the influence of various factors. Exposure to natural water sounds resulted in the suppression of sympathetic activity and activation of the parasympathetic branch of the autonomic nervous system, leading to improved cardiovascular functional capacity. Conclusions: The application of the proposed AOG analysis methods has allowed us to come to the following conclusions. Depressive disorders serve as a basis for the development of specific cardiovascular problems, and early detection of predispositions to these issues is crucial. The beneficial impact of the “Water” video composition can be used as a psychomodulating factor for restoring organismal homeostasis.
