Effectiveness of Adult Chest Compressions during Resuscitation Performed by Children Aged 10–14 Years under Simulated Conditions

<b>Introduction:</b> Numerous educational programs recommend implementing the teaching principles of BLS from an early age. The aim of this study was to evaluate selected parameters of the quality of resuscitation performed by children aged 10-14 years during simulated circulatory arrest in an adult. <b>Materials and Methods:</b> The project involved four stages, culminating in students performing thoracic compressions on an adult simulator for 2 min. A digital analysis of the quality, depth, relaxation and rate of compressions allowed us to formulate results and conclusions. The authors' proprietary questionnaire form allowed for the correlation of criteria such as age, gender, body mass and past experience in first aid training of the participant. <b>Results:</b> A total of 149 girls and 130 boys were studied. The mean age was 12 years (SD ± 1.41). A directly proportional increase in body mass with participant age was observed (<i>p</i> < 0.000). Children as young as 10 years old achieved only 24.13% quality, while those at the age of 14 demonstrated a more than doubled value (67.61%). The minimum depth of chest compressions recommended for an adult (5-6 cm) was not reached in any age group. Girls from all grades achieved a mean quality of 44.69% (SD ± 32.57), while boys achieved a score of 60.23% (SD ± 31.74). On the other hand, in the case of evaluating thoracic relaxation, a significantly better result was achieved by girls compared to boys (66.14% vs. 56.78%; rho-Spearman test for <i>p</i> = 0.011). <b>Conclusions:</b> Age, sex and body mass play important roles in the quality of resuscitation provided by children. None of the age groups studied achieved the minimum mean depth during adult thoracic compressions under simulated conditions. It is recommended to modify school-based BLS classes to better match the exercises to students' predispositions.
