Division of Healthcare Informatics, Faculty of Healthcare, Tokyo Healthcare University - Japan
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.
Figure 1 Flow of BLS application
- 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.
Figure 2 User test
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.
