Effective CPR Procedure With Real Time Evaluation and Feedback Using Smartphones.

Area of Science:

• Biomedical Engineering
• Emergency Medicine
• Mobile Health Technology

Background:

• Cardiopulmonary resuscitation (CPR) is critical in emergencies, but untrained bystanders may struggle with proper technique.
• Current 9-1-1 operator guidance relies on verbal instructions, which can be difficult to follow accurately.
• Optimizing CPR delivery is essential to improve patient survival rates.

Purpose of the Study:

• To investigate the efficacy of smartphone technology in enhancing CPR administration.
• To provide real-time feedback on CPR compression frequency and depth.
• To integrate blood oxygen saturation monitoring for dynamic resuscitation guidance.

Main Methods:

• Developed a smartphone application to analyze CPR compression parameters (frequency, depth).
• Integrated a feature to measure blood oxygen saturation via smartphone.
• Enabled real-time data transmission to 9-1-1 operators for enhanced guidance.

Main Results:

• Smartphone application achieved >90% accuracy in measuring compression frequency.
• >90% accuracy was demonstrated for compression depth measurement.
• Oxygen saturation monitoring also exceeded 90% accuracy, enabling timely interventions.

Conclusions:

• Smartphone-based systems can significantly improve CPR efficiency and accuracy.
• Real-time feedback and integrated monitoring enhance bystander CPR performance.
• This technology offers a promising tool for improving emergency cardiac care outcomes.
