Abstract

Interest in remote patient monitoring has grown significantly in recent years. We present a Patient Monitoring and Alert System that uses mobile and wearable technology to track vital signs like heart rate and blood oxygen levels (SpO₂). The system detects abnormal readings and sends instant alerts to caregivers or healthcare professionals through push notifications, SMS, and email. The mobile app is built using Flutter and connects to a wearable device using Bluetooth Low Energy (BLE) for real-time data transfer. We tested the system with 30 users and achieved a 95% success rate in delivering notifications, with fast data transmission (under 200ms via BLE), proving it to be a reliable solution for real-time health monitoring.
