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.

Quality of chest compressions (depth of chest compressions).
Chest compression depth will be evaluated by a manikin connected to a CPR software.
Time frame: During procedure
Quality of chest compressions (rate of chest compressions).
Chest compression rate will be evaluated by a manikin connected to a CPR software.
Time frame: During procedure
Quality of chest compressions (hand position of chest compressions).
Hand position during chest compression will be evaluated by observation.
Time frame: During procedure
Time factors of CPR
Measuring the time of check breathing, time to recognize cardiac arrest, time to first chest compression, and cumulative time of no-flow time by the CPR software and observation.
Time frame: During procedure
Attitude of bystanders.
Subjective feelings after performing CPR based on a short survey using Likert-scale based queries (lower numbers indicate worse, higher score indicates better opinion).
Time frame: Immediately after the CPR procedure (within 15 minutes)
