Video-assisted Telephone CPR With the EmergencyEye-Software - a Pilot Study - Proof of Concept

Study Overview
=================
Brief Summary
-----------------
Technical advance as broad-bandwidth wireless internet coverage and the ubiquity utilization of smartphones has opened up new possibilities which surpass the normal audio-only telephony. High quality and real-time video-telephony is now feasible. However until now this technology hasn't been deployed in the emergency respond service. In the hope of helping the detection of the cardiac arrest, offer the possibility to evaluate and correct via a video-instructed CPR (V-CPR) and to facilitate a fast localization of the emergency site, a new software (EmergencyEye®/RAMSES®) was developed which enables the dispatcher a video-telephony with the callers mobile terminal (smartphone) if suitable. This technology hasn't been tested in a randomized controlled trial in real environment conditions yet. This is to be done in this study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Recognition of CPR quality through video transmission | Recognition of CPR quality (3 conditions are randomized in each CPR, i.e. Frequency, Compression Depth, Compression Point) in Video-assisted CPR | 1 minute of CPR | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to first chest compression | Time measured from the beginning of the emergency call to the first chest compression | Study duration (approx. 1 minute) | 
| Precision of Geolocalisation | Precision of Geolocalisation, i.e. difference between verbally localized and automatically localized (aGPS) respondes to emergency call. Difference in runtimes of dispatched ambulances will be calculated | Study duration (approx. 1 minute) |
