Teaching resuscitation in elementary schools has several positive aspects. Students become aware of the importance of emergency medical assistance and the role they can play in saving lives. They acquire lasting competencies and skills that they can carry with them throughout life, contributing to greater safety and health awareness. Additionally, this approach can boost children's self-confidence and their ability to respond effectively in stressful situations. The focus of this research is on educating children about the basics of cardiopulmonary resuscitation (CPR), which includes: safe approach to the injured person, proper opening of airways, correct performance of chest compression, and artificial respiration. The conducted research aimed to determine whether educating students about CPR affects their knowledge of the subject. The study involved 96 fourth-grade students. For research purposes, an 8-question survey was created and administered to students before and after education on the fundamentals of life support. Educating children about the basics of resuscitation builds future generations into competent and self-aware individuals who are ready to provide first aid in critical situations. Through the creation of a knowledge chain, this initiative can have a long-term positive impact on the community and contribute to improving the quality of emergency medical care. Such skills are crucial in emergency medical situations, where rapid and correct intervention can significantly increase survival chances. Through practical exercises, simulations, and interactive teaching methods, children learn how to act correctly and provide emergency medical assistance until professional medical care arrives. Another key aspect of this approach is the expansion of knowledge to the broader community. Children often share their acquired skills and knowledge with family and friends, creating a chain of information dissemination. This can contribute to better preparedness and a stronger response in emergency situations, not only among children but also among those close to them.
