Wireless Network Based ICU Patient Monitoring System

Abstract : In modern healthcare, especially in intensive care units (ICUs), real-time monitoring of patient vitals is critical to ensure prompt medical intervention and improved outcomes. This project presents the development of a real-time ICU patient monitoring system using the ESP32 microcontroller integrated with advanced biomedical sensors. The system incorporates a DS18B20 digital sensor for precise body temperature measurement, analog sensors to monitor heart rate and respiratory activity, and an MPU6050 sensor to detect patient movement and potential fall events. These sensors collectively provide a comprehensive overview of a patient’s physiological state. The ESP32 serves as the central processing unit, collecting and wirelessly transmitting sensor data to a monitoring interface. Its built-in Wi-Fi and Bluetooth capabilities facilitate remote access and real-time alerts to healthcare providers, enabling immediate action in response to critical changes in patient conditions. The system is designed to be cost-effective, scalable, and suitable for deployment in both hospital ICUs and home-care settings. By leveraging real-time data acquisition and wireless communication, this solution enhances patient safety, reduces the burden on healthcare staff, and ensures timely medical responses. Furthermore, its modular architecture allows for easy integration of additional sensors, making it adaptable for diverse clinical needs. This work contributes toward the advancement of smart healthcare systems, supporting continuous monitoring, data-driven decision-making, and improved patient management in critical care environments.
