Randomised simulation trial found an association between rescuers' height and weight and chest compression quality during paediatric resuscitation

Aim: Our aim was to examine the relationship between rescuers' anthropometric data and chest compression quality during paediatric resuscitation training.

Methods: This study focused on 224 medical students (53% women) who performed 2 minutes of paediatric resuscitation at the Medical University of Vienna, Austria: 116 on a baby manikin and 108 on an adolescent manikin. Skill Reporter software measured chest compression quality by recording compression depth, frequency, hand position and complete recoil. The participants' height, weight and body mass index (BMI) were recorded.

Results: Participants with a lower BMI achieved higher total chest compression scores on both the baby and adolescent manikins than participants with a higher BMI. The latter were more likely to exceed the correct compression depth and not achieve complete chest recoil in the adolescent manikin. When it came to the baby manikin, the female participants achieved better chest recoil and the males achieved a higher number of compressions at the correct rate. Males also achieved better chest recoil with the adolescent manikins. Being tall only correlated with incomplete recoil in the adolescent manikin.

Conclusion: The results indicate that anthropometric variables were associated with chest compression quality in paediatric patients and should be considered by future education programmes.
