Effectiveness of Video-assisted Cardiopulmonary Resuscitation

Is Video-assisted Cardiopulmonary Resuscitation More Effective Than Telephone-assisted or Not-instructed Cardiopulmonary Resuscitation by Laypeople? - a Randomized Controlled Simulation Study

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.

Participants perform telephone-assisted CPR based on the European Resuscitation Council (ERC) 2021 guidelines.

Participants perform video-assisted CPR based on the European Resuscitation Council (ERC) 2021 guidelines.

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.

Subjective feelings after performing CPR based on a short survey using Likert-scale based queries (lower numbers indicate worse, higher score indicates better opinion).

Inclusion Criteria: healthy volunteer Exclusion Criteria: healthcare professionals (paramedics, nurses, etc.) pregnant women people with cardio-pulmonary and musculoskeletal diseases or any other impairment that would risk harm for the volunteer while performing CPR for 2 minutes psychological disabilities
