Establishment of blood pressure/pulse remote monitoring system using wearable device and IoT during dialysis

Abstract

【Background】Maintaining hemodynamic stability is vital for safe hemodialysis (HD) therapy. At present, circulatory dynamics are measured as appropriate. In this study, pulse and blood pressure are tracked via an automatic monitoring system to secure safer HD treatment and to enable remote monitoring and control via the detection and issuance of alerts. This study also aims to assist the development of instruments for remote monitoring and control. 【Method】We developed a wristwatch-like device that measures blood pressure and pulse and conducted a validation study on its effectiveness. We also constructed an IoT-type setup in which the measurement results are automatically sent to and stored on a server. 【Results】Each measurement item in our device provided the same level of detection accuracy as existing medical devices. Measurement results were managed on a server using an IoT system, and alerts were successfully triggered. 【Conclusion】There is potential for our system to be adopted in clinical practice to enable less stressful or demanding monitoring of patients and to ensure that the necessary alerts are issued by managing data using servers. We anticipate that more comprehensive safety management can be achieved by enhancing and improving the treatment environment for dialysis patients in this way.
