Study Overview
Brief Summary
The purpose of the study is to examine the effect of telephone assistance and standardized basic life support courses on the quality of cardiopulmonary resuscitation (CPR) and the use of automated external defibrillator (AED).
The investigators hypothesize that bystanders can provide compressions in correct frequency and use an AED correctly as well as safely from telephone instructions but that correct and successful ventilations including correct open airway require training on a course.
Detailed Description
The study aims at answering the following research questions:
- How is the quality of CPR and use of AED when performed by an inexperienced bystander who receives telephone assistance compared to the quality when performed by a trained bystander, who has passed a standardized European Resuscitation Council (ERC) course in basic life support (BLS) but does not receive telephone assistance?
- How is the quality of CPR and use of AED when performed by a trained bystander who has passed a standardized ERC course in BLS and who receives telephone assistance compared to the quality when performed by a trained bystander who does not receive telephone assistance?
The questions are sought answered through simulated cardiac arrest scenarios in non-classroom settings.
Participants are recruited from ERC courses in BLS.
Participants are randomised to one of three groups (stratified for course type using computer-generated randomisation lists with blocks of variable sizes):

Outcomes
Primary Outcomes
Compression rate
Time Frame: 8 minutes
Rescuer keeps a compression rate of approximately 100-120 compressions per min. throughout the CPR (yes/no). Measured by advanced manikin.
Shock delivered
Time Frame: 8 minutes
Shock delivered with AED (yes/no). Assessed by ERC instructor.
Compression depth
Time Frame: 8 minutes
Keeps a compression depth as recommended by International Liaison Committee on Resuscitation (ILCOR) (5-6 cm) on at least 50 % of compressions (yes/no). Measured by advanced manikin.
