Abstract

BACKGROUND

Cardiopulmonary resuscitation (CPR) guidelines vary in the terminology used to describe target chest compression depth, which may impact CPR quality. We investigated the impact of using different chest compression depth instruction terminologies on CPR quality.

METHODS

We conducted a parallel group, three-arm, randomised controlled manikin trial in which individuals without recent CPR training were instructed to deliver compression-only CPR for 2-minutes based on a standardised dispatcher-assisted CPR script. Participants were randomised in a 1:1:1 ratio to receive CPR delivery instructions that instructed them to deliver chest compressions based on the following terminologies: 'press at least 5cm', 'press approximately 5cm' or 'press hard and fast.' The primary outcome was compression depth, measured in millimetres.

RESULTS

Between October 2017 and June 2018, 330 participants were randomised to 'at least 5cm' (nn=109), 'approximately 5cm' (nn=110) and 'hard and fast' (nn=111), in which mean chest compression depth was 40.9mm (SD 13.8), 35.4mm (SD 14.1), and 46.8mm (SD 15.0) respectively. Mean difference in chest compression depth between 'at least 5cm' and 'approximately 5cm' was 5.45 (95% confidence interval (95%CI) 0.78 to CI) 0.78-10.12), between 'hard and fast' and 'approximately 5cm' was 11.32 (95% CI 6.65 to -15.99), and between 'hard and fast' and 'at least 5cm' was 5.87 (95% CI 1.21 to -10.53). Chest compression rate and count were both highest in the 'hard and fast' group.

CONCLUSIONS

The use of 'hard and fast' terminology was superior to both 'at least 5cm' and 'approximately 5cm' terminologies.
