Sleep breathing disorder is a pathological condition characterized by changes in respiratory parameters, which includes obstructive sleep apnea syndrome, which, according to modern research, is associated with cardiovascular diseases. The high prevalence of this pathology and the lack of practical possibility to perform an in-depth examination of all potentially needy people necessitates the development of new diagnostic principles. In this article, the method of magnetic plethysmography as a noninvasive method of diagnostics of obstructive sleep apnea syndrome was considered. The model of biotechnical system was designed and manufactured, taking into account the requirements for ergonomics and low cost, the software for data reception and visualization was developed, an algorithm for automatic registration of respiratory movements frequency was proposed, and the product was tested. According to the results of the research, the performance of the product was proven: the ability to register respiratory wave from the thoracic and abdominal surface, the selection of respiratory rate and heart rate, nighttime sleep monitoring, the ability to detect apnea episodes, the ability of the algorithm to automatically register respiratory rate. It is concluded that the biotechnical system can be used for screening patients with obstructive sleep apnea syndrome and needs further development. |
