Background and objectives: Currently, emergencies from complications, congenital disease, or physical pathology, such as out-of-hospital cardiac arrest (OHCA), are important causes of death and hospital admission, and sudden cardiac arrest occurs until the heart stops working immediately. This study aims to To examine the results of repeated measurements with Qualitative Confirmation of results, knowledge, understanding, chest compression skills, use of AEDs, and basic life support for village health volunteers (VHV). Methods: This mixed-method. Phase 1 quasi-experimental research. The sample group consisted of 30 Village Health Volunteers (VHV) selected using a simple random sampling method. The tool used in this research was the basic life support program that seduces a group process. Knowledge assessment form and basic life support skills. Data collection was performed by repeated measurement six times; Phase 2, qualitative research by discussing Basic life support program of Village Health Volunteers (VHV) that participated in the quantitative research program. After the 6th follow-up repeat measurement for one month, the sample was selected randomly from 10 participants in the program in phase 1. Quantitative data were analyzed using descriptive statistics, one-way analysis ANOVA with repeated measures, and statistical data. Qualitative data were analyzed using content analysis. Results: The findings of the quantitative study showed that Village Health Volunteer (VHV) had knowledge scores on patient assessment and environment, chest compression, use of AED, and basic life support. From each measurement, there was a better direction statistically significant at the qualitative level of 0.01. Conclusion: Basic life support program using group processes can develop potential and increase confidence in knowledge and understanding, skills in patient assessment and environment, chest compression, use of AED, and basic life support. Therefore, knowledge, understanding, and basic life support skills should be regularly and continuously reviewed to ensure resuscitation efficiency. Word count: 5,578 words, excluding references.
