Personal protective equipment has become the last line of protection for medical personnel during the pandemic of the new coronavirus infection since it allows minimizing risks of biological contagion. Given the existing staffing shortage, medical workers have to spend from 4 to 12 hours a day in the “red zone” where they necessarily wear personal protective equipment. Protective clothing is known to produce negative effects on functional state of the body and personnel’s working capacities. Assessment of up-to-date protective suits will allow developing recommendations on their suitable application bearing in mind a balance between necessary protection, providing favorable ergonomics, and reducing risks of adverse effects on functional state and working capacities. Our research aim was to hygienically assess health risks for medical workers who had to wear reusable protective suits. Our research object was a reusable suit made from polyether fabric with polyurethane membrane coating and antistatic threads. We performed an experiment aimed at evaluating thermal state of the body, psychophysiological state, and responses by the volunteers’ cardiorespiratory system in laboratory conditions during an 80 hour working shift under controlled microclimate. Participants in the experiment were questioned in order to assess suits’ ergonomics. Heat exchange dynamics and amount of changes in thermal physiological parameters caused by wearing a protective suit determined heat contents of volunteers’ bodies that conformed to optimal standard values. Data on psychophysiological and mental state taken in research dynamics didn’t have any statistically significant changes. Gas exchange indicators naturally grew during the “load” phase; however, there were no significant changes detected in any phase in the research. Hygienic assessment of the thermal state, functional state of the cardiovascular and respiratory systems, and psychophysio-logical indicators confirmed that wearing a protective suit was quite safe and didn’t involve any health risks for volunteers.

BACKGROUND: The use of personal protective equipment in contact with patients with new coronavirus infection is the basic measure to ensure the safety of medical personnel. It is known that the use of protective equipment made of materials with low hygroscopicity, air and vapor permeability, under high ambient temperatures and physical activity, can cause overheating of the body. Objectively, during the pandemic, medical personnel reported a deterioration in the functional state up to and even fainting, caused by prolonged use of protective suits. Protective equipment made it difficult to perform routine tasks and led to a reduction in the quality of work performed. PURPOSE OF THE STUDY: Assessment of the effect of personal protective equipment on the functional status of medical personnel. MATERIALS AND METHODS: A survey of 156 medical workers of military medical organizations was carried out using the original questionnaire. The ease of use of protective equipment was assessed, and at the same time the negative aspects of its use were identified. A study of the thermal condition of 6 volunteers during the use of reusable and disposable personal protective equipment sets was carried out under laboratory conditions. RESULTS AND DISCUSSION: The majority of respondents reported a negative impact on the functional state of the body when using personal protective equipment. According to questionnaire data, skin damage occurred in 88% of cases; fogging of safety glasses in 81%; visual impairment in 70%; inadequate suit size in 61%; subjective feeling of heat at work in 61%; headaches in 45% of cases. An assessment of the thermal condition of the reusable and disposable suits at a temperature of 25C and light physical work indicated that the body heat levels of the volunteers were within acceptable normative values. CONCLUSIONS: The use of personal protective equipment has a negative effect on the functional state of the medical workers body, which requires a rational approach to the selection of protective the provision of an optimal regime of work and rest Considering the possibility of using personal protective equipment under different conditions, including increased ambient temperatures (over +30С) and/or intense physical exertion, there is a need for further study of their effects in order to develop preventive measures.

The article presents scientifically based methods and techniques for determining the level of energy consumption, which are most appropriate and convenient for practical use in mass physiological and hygienic and experimental studies, depending on their goals and objectives.Determination of the amount of human energy consumption should be carried out by monitoring studies during the shift, followed by the calculation of the weighted average heart rate, considering the different types of work performed, technological breaks and downtime. It is necessary to take into account the full range of environmental factors and the work process that contribute to the physical and thermal stress of working men and women in accordance with their age and body weight.
