Registration of the Breathing Pattern and ECG by the Electroimpedance Method in a Portable Parting

Assessment of the athlete’s functional state is a very important task of modern medicine. This article describes the development of a portable device for recording respiratory parameters and electrocardiography. In order to develop a device, it is necessary to choose the method on the basis of which it will work, as well as analyze analogs in order to understand which parameters to focus on. In this paper, the electrical impedance method is chosen, since it is noninvasive, relatively accurate and easy to use, as well as a device based on this method can be made of small dimensions, which is very important for our task. The biotechnical system circuit, the structural scheme of the recorder, and the overall appearance of the device have been designed, and the technical parameters of the device are provided. The scheme of the biotechnical systemBTS reflects the principle of operation, reproducible parameters, and the necessary blocks are indicated. The block diagram describes the structure of the device - its technical part is considered in the most detail, the nodes necessary for the operation of the device are given. The general diagram shows the dimensions of the device and its structural components.
