Smart blood pressure holter

Area of Science:

• Biomedical Engineering
• Medical Devices
• Cardiovascular Technology

Background:

• Traditional blood pressure monitoring can be invasive and inconvenient.
• There is a need for portable, user-friendly devices for continuous cardiovascular assessment.

Purpose of the Study:

• To develop a wireless blood pressure holter utilizing smart mobile devices.
• To assess the accuracy and reliability of this novel monitoring system.

Main Methods:

• A two-part system comprising a smart mobile device and an arm cuff was designed.
• Bluetooth connectivity, RC and digital filters, and the Hill Climbing Algorithm (HCA) were employed for data acquisition and processing.
• The system allowed for instantaneous or programmable measurements of blood pressure and heart rate.

Main Results:

• The wireless holter achieved high accuracy rates: 93.89% for systolic pressure, 91.95% for diastolic pressure, and 97.66% for heart rate, when compared to a traditional sphygmomanometer.
• Continuous monitoring in holter mode demonstrated reliable Bluetooth connectivity and measurement consistency.
• The device operated for over 24 hours on four alkaline batteries at 20-minute intervals.

Conclusions:

• The developed smart blood pressure holter meets the performance standards of classical holter devices.
• The system offers accurate and reliable wireless monitoring of blood pressure and heart rate.
• Its integration with smart mobile devices enhances user accessibility and convenience for long-term cardiovascular monitoring.
