Cardiac Arrest
Conditions
Brief summary
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.
Detailed description
Sudden cardiac arrest is a major public health problem worldwide and it is one of the leading causes of death in industrialized countries. 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 (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.
Interventions
OTHERVideo-assisted CPR
Participants in V-CPR group get video-based (vocal and visual) instructions from the dispatcher.
Participants in T-CPR group get voice-based (vocal) instructions from the dispatcher.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Quality of chest compressions (depth of chest compressions). | During procedure | Chest compression depth will be evaluated by a manikin connected to a CPR software. |
| Quality of chest compressions (rate of chest compressions). | During procedure | Chest compression rate will be evaluated by a manikin connected to a CPR software. |
| Quality of chest compressions (hand position of chest compressions). | During procedure | Hand position during chest compression will be evaluated by observation. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time factors of CPR | During procedure | 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. |
| Attitude of bystanders. | Immediately after the CPR procedure (within 15 minutes) | Subjective feelings after performing CPR based on a short survey using Likert-scale based queries (lower numbers indicate worse, higher score indicates better opinion). |
