Advancing Remote and Continuous Cardiovascular Patient Monitoring through a Novel and Resource-efficient IoT-Driven Framework
To address the challenge of home-based cardiovascular disease monitoring for aging populations in low-infrastructure regions such as Pakistan, this study proposes a lightweight embedded–cloud–edge collaborative IoT system. The hardware integrates low-power sensors—including MAX30102 and AD8232—to concurrently acquire heart rate, blood pressure, blood oxygen saturation, body temperature, and ECG signals. A dual-mode LoRa/WiFi communication protocol enables energy-efficient data transmission to an AWS cloud platform, supporting scalable remote health monitoring. The system introduces a novel threshold-driven, millisecond-level anomaly detection algorithm with automated clinician alerts, achieving end-to-end alert latency under 800 ms. Clinical validation (n=20) demonstrates measurement errors <2% relative to gold-standard clinical devices across all key parameters; the system sustained uninterrupted operation for over 30 days. This architecture significantly enhances accessibility and reliability of chronic disease management in resource-constrained settings.
