Abstract
Objective: to compare the acquisition of skills to recognize cardiac arrest through training with mixed-level groups versus traditional training. Methods: A quasi-experimental study without pre-testing was conducted with 312 schoolchildren aged between 3 and 12 years. The sample was divided into two groups: the mixed-level group (n=149), which received theoretical and practical training in sessions with students from all grades; and the control group (n=163), which received training in sessions with students from the same grade. After the session, all schoolchildren were assessed with a Laerdal Little Junior manikin and a checklist by qualified personnel. Results: No significant differences were observed between the two groups in the steps of remaining calm when cardiac arrest occurs and calling 112 (European emergency number). Better results were observed in the control group participants in the steps of assessing the victim's response, opening the victim's airway, and assessing the victim's breathing. Conclusion: From the point of view of assimilating skills in the recognition and treatment of cardiac arrest, the interlevel group approach was less effective than a traditional approach.
