Homepage Overview

RhytmoGuard is a revolutionary AI-powered, cuffless blood pressure monitoring system developed under the TUBITAK 1501 Program (Grant No: 2340651). Designed to redefine hypertension management, this MR Conditional-compliant wearable enables continuous, non-invasive blood pressure tracking while synchronizing pulse rate, SpO2, and motion data. Ideal for chronic disease patients, elderly users, and active lifestyles, RhytmoGuard bridges the gap between clinical precision and everyday usability.

About the Project

RhytmoGuard aims to eliminate the limitations of traditional cuff-based blood pressure monitors by integrating AI-driven analytics, dual optical sensors, and MR-safe materials. Its cuffless design ensures patient comfort, while real-time data streaming empowers users and clinicians to make informed health decisions.

Key Features

Multi-Parameter Monitoring: Simultaneously acquires:

Cuffless Continuous Monitoring : Measures systolic/diastolic BP without restrictive arm cuffs.

AI-Powered Analytics : Machine learning algorithms refine accuracy using PPG, SpO2, and accelerometer data.

Dual Optical Sensors : Two medical-grade oximeters for redundant, high-fidelity pulse wave analysis.

MR Conditional Compliance : Safe for use in 3 Tesla MRI environments (non-magnetic, RF-shielded components).

Smartphone Integration : Android/iOS app for real-time visualization, historical trends, and HD video sync.

Wearable Design : Lightweight, wrist-worn device with 6+ hours of battery life.

Innovation & Technology

AI-Driven Blood Pressure Estimation

RhytmoGuard’s proprietary algorithm combines Pulse Transit Time (PTT), Pulse Wave Velocity (PWV), and PPG waveform morphology to estimate BP. Machine learning models trained on diverse datasets reduce motion artifacts and improve accuracy during activity.

Dual-Sensor Advantage

Two optical sensors minimize signal noise and enable cross-validation, ensuring reliable readings even during movement.

HD Video Synchronization

The app pairs BP trends with HD video recordings (via smartphone camera) to contextualize physiological responses during specific activities or stressors.
