Today, there are personal protective equipment, which due to their weight and size characteristics and design features can aggravate professional activity. This is characterized by an increase in the load on several major systems of the employee's body, including the cardiorespiratory system, which can cause the development of occupational pathology. The study of the functions of the cardiorespiratory system of humans in the process of his work is an important task in biomedical tests such as PPE, aggravating their professional activities and future means of individual protection from heavy labor and industrial exoskeletons. The aim of the study is to determine the possibility of using ergospirometry for the physiological assessment of personal protective equipment and industrial exoskeletons. Main part. In medical practice and high-performance sports, ergospirometry is considered the "gold standard" for functional assessment of the cardiorespiratory system. There are very few studies showing the use of ergospirometry for the purpose of physiological assessment of personal protective equipment. Results of research works in which ergospirometry was used in medicine, sports, as well as on the physiological and hygienic assessment of combat equipment, various types of personal protective equipment, including new promising personal protective equipment of the musculoskeletal system-industrial exoskeletons. The use of ergospirometry made it possible to register the main indicators of the human cardiorespiratory system both in field and laboratory conditions and allowed forming an objective conclusion about the dynamics of the degree of stress of the human cardiorespiratory system when using personal protective equipment and industrial exoskeletons with various weight and size characteristics. Thus, the use of ergospirometry both in isolation and in combination with other methods allows us to solve problems related to biomedical testing of personal protective equipment and industrial exoskeletons.

Restoring perfusion to ischemic tissue is the primary goal of acute ischemic stroke care, yet only a small portion of patients receive reperfusion treatment. Since blood pressure (BP) is an important determinant of cerebral perfusion, effective BP management could facilitate reperfusion. But how BP should be managed in very early phase of ischemic stroke remains a contentious issue, due to the lack of clear evidence. Given the complex relationship between BP and cerebral blood flow (CBF)—termed cerebral autoregulation (CA)—bedside monitoring of cerebral perfusion and oxygenation could help guide BP management, thereby improve stroke patient outcome. The aim of INFOMATAS is to ‘ identify novel therapeutic targets for treatment and management in acute ischemic stroke’. In this review, we identify novel physiological parameters which could be used to guide BP management in acute stroke, and explore methodologies for monitoring them at the bedside. We outline the challenges in translating these potential prognostic markers into clinical use.

This thesis examined the role of viewing a picture of one’s pet as a mechanism for alleviating the symptoms of stress. The mental arithmetic task (MAT), a psychosocial stressor was used to induce stress. Participants were randomly assigned into one of six visual conditions: either a picture of their personal pet (n = 9), an unfamiliar animal (n = 9), a person who is supportive and important to the participant (n = 9), an unfamiliar person to the participant (n =8), a pleasant image (control 1) (n = 8) or no image (control 2) (n = 8). Stress reactivity, both physical (e.g., blood pressure) and subjective (self-reported anxiety), were measured. Findings indicated that contrary to the hypothesis, viewing a picture of one’s personal pet did not reduce stress reactivity, measured either subjectively (self-report) or objectively (physiological assessment). However, the study suggests that various images can influence stress reactivity.
