Background Today, most medical dispatchers are blind to what happens at the scene and have no objective data to use in rescuer coaching.

We wanted to develop a technical solution where CPR quality data and video is streamed to the dispatcher. The CPR and video allow for targeted coaching and teamwork with the rescuer, aiming to improve CPR quality.

Method We developed a single-use, accelerometer-based CPR feedback device with Bluetooth communication with a smartphone app. The credit card sized device is placed between the patient’s bare chest and the rescuers hands. It measures compression depth and rate and provides visual feedback to the rescuer. The card streams CPR data real-time to the app, which provides enhanced visual feedback on CPR performance. This app further streams the CPR data and video to a server on the internet. Real time CPR feedback and video are securely made available for the dispatcher on a web solution, to use when coaching the rescuer in CPR.

Results Results from 160 simulation runs with volunteers showed that the technical solution provides real time feedback to the rescuer while streaming real time CPR data and video to the dispatcher. The dispatcher used this CPR data and video to coach quality of CPR.

Conclusion The TCPR Link system can connect less experienced CPR volunteers with more experienced dispatchers to improve teamwork and CPR performance. The system is planned to be used in a clinical trial by first responders activated by the dispatch center, in a 5M city.
