Abstract:

Intensive Care units (ICUs) require constant monitoring of critical patients to detect abnormalities in vital physiological parameters as early as possible. Existing monitoring devices in ICUs are expensive, fixed, not portable, and contain challenges in scaling critical-care in resource-limited settings. This project introduces a patient monitoring and smart alarm system able to deliver IoT-enabled, real-time data collection, wireless transmission, cloud storage, and emergency alert. Biomedical sensors including MAX30102, AD8232, and DS18B20 integrated with ESP8266 NodeMCU can measure heart rate, oxygen saturation (SpO₂), electrocardiogram (ECG), and one body temperature. The vitals are uploaded to a cloud server where the medical staff can then visualize the live vitals on a remote dashboard. Threshold based decision algorithms will sound visual alarms and send notifications via phone to ensure timely intervention. Upon realizing this prototype it was able to obtain an accuracy of about 96% under controlled stable conditions and through using the system made monitoring possible and unstable variable that was previously unnoticed . The system demonstrates an affordable supportable approach to implement technologies face a digital transformation of critical health-care architecture.
