Background
  • Basic Life Support (BLS) education has widely been introduced for general citizens.
  • However, if general citizens (lay rescuers) encounter a situation wherein they should perform a BLS process, these lay rescuers cannot always perform the necessary actions as per the required guidelines.
  • Here we developed a BLS guide application for the lay rescuer.
Summary of Work
  • We developed an Android application based on the AHA guideline 2010.
  • In this application, a series of BLS processes, such as consciousness recognition, emergency calling, chest compression administration, and automated external defibrillator (AED) usage, were navigated using a series of displayed pictures and texts with voice guides.
  • The application showed what to perform at each step and how to perform it.

  • We conducted basic user tests to investigate the potential and utility of the application.
  • Participants were five university students.
  • All of them had undergone some BLS training more than once before the tests.
  • Using the application, the students were asked to perform BLS processes in a scenario where an adult male teacher suddenly collapsed and became unconsciousness.
  • We evaluated BLS performance using a 10-item checklist.

Summary of Results
  • Our results showed that the number of correctly performed steps were an average of 5.6 items.
  • All the students correctly performed the step of asking someone to bring an AED.
  • However, 80% failed tocorrectly perform the step of asking someone to prepare the AED for use.

Conclusion
  • We developed a Basic Life Support guide application usable on Android devices for lay rescuers.
  • With regard to the utility of the application, all students answered that it helped them perform the appropriate BLS processes.
