The Efficacy of Basic Life Support Education Among Teenagers

Study Overview
=================
Brief Summary
-----------------
Basic life support (BLS) skills are crucial not only for healthcare workers but for all lay people as well. Timely recognition of out-of-hospital cardiac arrest and the initiation of BLS by bystanders before the arrival of healthcare personnel can improve survival. There are several methods of spreading BLS skills and improve BLS skill retention among lay people. One of these methods can be educating school children. The introduction of mandatory BLS education in schools was very effective in some European countries to increase the rate of bystander BLS. The current study aims to investigate the efficacy of a BLS training and BLS curriculum among high school children in Hungary. Moreover, the investigators would like to optimise factors influencing skill retention in this first responder group and aim to compare two types of teaching methods: feedback given by the instructor or software-based feedback on the efficacy of chest compressions during the course.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Instructor feedback<br>BLS training participants will receive feedback from an experienced instructor certified by European Resuscitation Council on the depth and frequency of chest compressions, duty cycle, chest recoil and the quality of ventilation. | Other: Instructor feedback<br>* Feedback is given by the opinion and observation of an experienced instructor.<br>|
| Experimental: Software feedback<br>BLS training participants will receive feedback based on a software built in the Ambu Man C Torso (Ambu A/S, Copenhagen, Debmark) on the quality of chest compression (exact frequency, depth of chest compression, chest recoil and duty cycle) and tidal volume during ventilation. | Other: Software based feedback<br>* Feedback is given by the data of a software built in Ambu Man C Torso (Ambu A/S, Copenhagen, Denmark).<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| End of training BLS skill assessment based on a checklist | BLS skills measured right after the training based on a checklist including the most important steps of BLS and quality of chest compression. The assessment will be performed by one or two instructors and the built-in software of Ambu Man C torso. | up to two hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| BLS skill assessment after 2 months based on a checklist | BLS skills measured 2 months after the training based on a checklist including the most important steps of BLS and quality of chest compression. The assessment will be performed by one or two instructors and the built-in software of Ambu Man C torso. | 2 months | 
| BLS skill assessment after 6 months based on a checklist | BLS skills measured 6 months after the training based on a checklist including the most important steps of BLS and quality of chest compression. The assessment will be performed by one or two instructors and the built-in software of Ambu Man C torso. | 6 months |
