Sudden cardiac arrest is a major public health problem worldwide and it is one of the leading causes of death in industrialized countries. Emergency Medical Services (EMS) dispatchers play an important role to recognize cardiac arrest and give help to the lay first responder via telephone CPR (T-CPR) which improves survival rates. The current technology allows the live video connection between the scene and the dispatcher which provides the opportunity for video-assisted CPR (V-CPR) via the bystander smartphone.

Effectiveness of V-CPR has only been investigated to a limited extent. Comparing effectiveness of V-CPR (effectiveness of chest compression, time parameters eg. time to first chest compression) to T-CPR and non-instructed CPR can be useful to implement V-CPR technology.

Effectiveness of V-CPR has only been investigated to a limited extent. Comparing effectiveness of V-CPR (quality of chest compressions: depth, rate, hand position), time parameters: time to recognize cardiac arrest, time of check breathing, total no-flow time, to first chest compression) to T-CPR and non-instructed CPR can be useful to implement V-CPR technology.
