EFFECT OF TEACHING CPR WITH A FEEDBACK MANIKIN ON RESCUE AND LIFESAVING STUDENTS AGED 11 TO 16
Abstract
Introduction: Out-of-hospital cardiorespiratory arrest (OHCA), due to its high incidence and mortality rate, is a priority public health problem worldwide. It is vitally important to train the lay population in manoeuvres that allow them to recognise and act on this situation, since on most occasions they are the first witnesses with the capacity to act.
Objective: to compare the quality of cardiopulmonary resuscitation (CPR) manoeuvres between a group of children who trained with conventional manikins and another group who used positive feedback manikins.
Methodology: longitudinal experimental study with case and control group on a total sample of 33 athletes from 11 to 16 years old. The quality of different parameters of the cardiopulmonary resuscitation manoeuvres (CPR) was analysed and compared between the intervention group, which carried out the training with dummies with a positive feedback system, and the control group, which used conventional dummies. Simultaneously, a cross-sectional descriptive observational study was conducted in both groups to assess the sequence of basic life support (BLS) and a pre-post study to identify the level of knowledge improvement after the educational intervention.
Results: the students tested significantly increased their level of knowledge and were mostly able to follow the SVB sequence correctly. Statistically significant differences were obtained between both groups in several parameters of the compressions, position of hands (p<0.001), total number of compressions (p<0.001) and percentage of correct depth (p=0.037), as well as of the ventilations, average volume (p=0.01) and percentage of ventilations that do not reach the adequate volume (p=0.04).
Conclusions: the educational intervention increased the level of knowledge and skills about the BLS among children. The intervention group, which operated with positive-feedback manikins, obtained better results according to the CPR parameters.
