Advanced Real-Time Patient Health Monitoring System

The rapid advancement of technology has brought transformative changes in the field of the healthcare system in recent years. Since they can enhance the quality and accessibility of healthcare services, particularly for patients with chronic conditions or in rural regions, microcontroller-based health monitoring systems have been extensively researched and developed in recent years. This paper presents a system capable of multiple measurements and improved ability of health parameters with a cost-efficient solution with reliability and portability. The proposed system is able to measure the parameters at an accuracy of 97.8% in terms of heart rate, blood pressure, body temperature, and oxygen saturation. The system also proposes continuous monitoring of the patient’s health status by collecting data from sensors attached to the patient’s finger and transmitting it wirelessly to a central database via Blynk where the healthcare provider can monitor the results in real-time and provide immediate feedback.
