Introduction In modern medicine, continuous and precise monitoring of patient condition is one of the most critical tasks. This is particularly important for chronic diseases, cardiovascular, respiratory, and metabolic disorders, where timely diagnosis and prompt intervention can be life-saving. Traditional monitoring methods often require constant patient interaction and are limited in the parameters they can record, which restricts early detection of pathological changes. Therefore, integrating artificial intelligence (AI) and Internet of Things (IoT) technologies into patient monitoring systems has become increasingly significant in contemporary healthcare. Through IoT systems, various biophysical indicators such as heart rate, blood pressure, oxygen saturation (SpO₂), body temperature, and other physiological parameters can be continuously collected from the patient and transmitted to central servers or mobile applications for analysis. When combined with AI algorithms, these systems enable early detection of abnormal physiological patterns, provide timely alerts, and support clinical decision-making. Additionally, such systems facilitate remote monitoring, reduce the workload of medical staff, and serve as a primary data source for developing personalized treatment strategies. Moreover, intelligent IoT systems based on biophysical indicators can provide real-time monitoring tailored to the individual patient’s physiological characteristics. This approach not only improves diagnostic accuracy but also enhances the management of chronic diseases, post-surgical recovery, and intensive care processes. 105 ResearchBib IF - 11.01, ISSN: 3030-3753, Volume 2 Issue 12 Therefore, this topic is highly relevant not only for modern medicine and biomedical engineering but also for the future development of precision and personalized healthcare.
