PSYCHOPHYSIOLOGICAL ASSESSMENT OF THE LABOR OF MEDICAL WORKERS IN ORGANIZATIONS WITH COVID-19
Abstract. Introduction. High neuro-emotional stress among medical workers in organizations with the leading harmfulness of Covid-19 contributes to the formation of an unfavorable functional state, increases the risks of health disorders. The study of the characteristics of the psychophysiological reactions of the body will allow to substantiate the timing of work in a pandemic, which is quite relevant at the present time. The purpose of the research was, on the basis of comprehensive psychophysiological studies, to study the features of the formation of a functional state in medical personnel working in organizations with COVID-19 under the influence of stress factors of the labor process. Materials and methods. A physiological and hygienic assessment of the intensity of the labor process was carried out, psychophysiological changes were studied during 3 months of work in the «dangerous» zone. Statistical processing of the obtained data was carried out using the statistical programs Statistika 10, Microsoft Excel 2010. Results. The formation of neuropsychic stress in medical workers is reflected in changes in ECG indicators (prolongation of the QT interval, decrease in the voltage of the P and T waves) and systemic arterial pressure, an increase in the endurance coefficient (an indicator of detraining of the cardiovascular system), positive values of the Kerdo autonomic index (predominance of sympathetic influences) after 3 months of work in medical organizations with Covid-19. Conclusions. Nervous and emotional tension at work is the leading professional factor among nurses and doctors working in medical institutions with Covid-19 (hazard class 3, grade 3). Indicators of the cardiovascular system, reflecting the degree of adaptation of the body of medical workers to production activities, can be used to justify different periods of work in organizations with Covid-19.
