Abstract
At the current time, in connection with the COVID-19 pandemic, the development and implementation of rehabilitation measures is an acute issue. At the same time, the use of new technologies will improve the rehabilitation process and achieve significant results. This paper discusses examples of medical systems that are used to train the respiratory system, as well as allowing to get biofeedback and use the received data to further improve the process. As a result of the review, the development of a software and hardware complex for monitoring and correcting respiratory functions for the rehabilitation of patients with respiratory problems is considered. This breathing simulator will not only allow to observe the work of the human body during the training process, but also use observation data to improve training results, which in turn can have a significant positive effect in the rehabilitation of patients.
