This monograph presents a comprehensive interdisciplinary approach to the study, measurement, and analysis of human functional status under conditions of increased stress, with a focus on spaceflight.
It examines the main physiological and psychophysiological effects of microgravity, cognitive stress, and adaptive mechanisms, as well as the requirements for reliable monitoring of the human operator as an element of the “human-machine” system.
The monograph systematizes key indicators for assessing a person’s condition—cardiovascular, respiratory, neurophysiological, and integrated psychophysiological indices—which allow for an objective assessment of work capacity and adaptive capacity. Special attention is given to biomedical sensors, their principles of operation, classification, and limitations, as well as the requirements for their operation in extreme environments, including microgravity, radiation, and temperature variations.
