Introduction Cardiopulmonary resuscitation (CPR) by a bystander can increase the survival rate of patients experiencing out-of-hospital cardiac arrest (OHCA). However, performing high-quality CPR using the standard hand-only technique may not be possible in cases where the bystander is a child. In special situations, it has been found that using the foot for chest compressions is equally effective as using the hand in adults. However, the effectiveness of this method when the bystander is a child is under-researched. Thus, we aimed to investigate the efficacy of chest compressions performed using a foot compared to those performed using a hand in children under 15 years of age. The investigation focused on three key parameters: 1) compression rate, 2) compression depth, 3) percentage of full chest recoil over two minutes.
Method This crossover randomized controlled trial study was conducted between January and October 2023. We recruited 44 student participants aged 13-15 years. The participants used CPR Training Manikins with feedback data. Methods of chest compressions were assigned by simple random sampling, and after two minutes, the participants switched to the alternative method.
Results Compression rate by hand exceeded by foot (11.3±14.2 bpm, P<0.001), while the percentage of full chest recoil by hand surpassed that during foot compressions (26.2±23.9%, P<0.001). Conversely, compression depth by foot was greater than by hand (-14.7±7.4 mm, P<0.001).
Conclusion In school-aged children, chest compressions using a foot have an advantage in compression depth compared to hand compression. However, manual chest compressions maintain a faster compression rate and a higher percentage of chest recoil, aligning with established standards. The weight of the chest compressor does not significantly impact the overall efficiency of chest compressions.
