RescueDoppler – Continuous Blood Flow Monitoring During Cardiac Arrest
RescueDoppler is a hands-free carotid Doppler ultrasound technology developed to improve monitoring and decision-making during cardiac arrest and cardiopulmonary resuscitation (CPR). Using a clinically relevant porcine cardiac arrest model, the project demonstrates that continuous Doppler monitoring of carotid blood flow can reliably detect the presence or return of spontaneous circulation without interrupting chest compressions.
The studies show that RescueDoppler can identify return of spontaneous circulation (ROSC) in real time, reducing the need for manual pulse checks and minimizing pauses in CPR. This addresses a well-known limitation of current resuscitation practice, where pulse checks are often inaccurate and contribute to harmful interruptions in chest compressions.
By combining a robust large-animal cardiac arrest model with hands-free Doppler technology, RescueDoppler provides a translational platform for improving resuscitation quality, guiding clinical decisions, and supporting future development of non-invasive circulatory monitoring tools in emergency and critical care settings.
