No intervention

Outcome(s)

• Primary Outcome: The number of appropriate chest compressions during a 2-min test period 6 months after the initial training. The appropriate chest compressions are defined as one with a depth of 5.0 to 6.0 cm, an interval of 0.5 to 0.6 seconds from the previous compression, and complete recoiling according to the JRC resuscitation guidelines.
• Secondary Outcome: Items obtained in the simulation test at the 6-month mark after the initial training A. Items to be obtained during 2-min test period Number of chest compressions Number of chest compressions with depth of 5.0 to 6.0 cm Number of chest compressions performed at intervals of 0.5 to 0.6 seconds Number of chest compressions with complete recoiling Number of chest compressions performed with appropriate hand position The proportion of the above five items calculated by dividing by 220, which is the theoretically appropriate number of chest compressions in 2 minutes according to the JRC Resuscitation Guidelines. Average chest compression depth Average chest compression rate Time from start of scenario to check for responsiveness Time from start of scenario to start of chest compressions Time from arrival of the AED to turning on the AED Time from arrival of the AED to defibrillation by AED Verify scene safety Check for responsiveness Call for help (119 calls) Check for breathing Call for AED Defibrillation by AED Position of attached AED pad B. Items to be obtained via the WEB form Confidence in performing BLS and change before and after the research period Willingness to perform BLS and change before and after the research period Whether or not participants encountered any situations that required CPR or AED Whether or not participants actually performed CPR or used an AED Whether or not the BLS course was taken Frequency of learning BLS using Liv Frequency of learning BLS using teaching materials other than Liv Opinions on Liv teaching materials Motivation for learning using Liv C. Items automatically obtained via Liv Number of completion Number of accesses Percentage of compliance with monthly Liv learning Average access time Percentage of chest compressions that were performed at an appropriate rate in each simulation Average rate of chest compressions in each chest compression simulation
