Comparison between a low-cost model (CPR Pillow) and a mannequin in training hands only cardiopulmonary resuscitation (CPR): A randomised trial

Abstract

Introduction: CPR is an important lifesaving skill that can improve outcomes of patients in cardiac arrest. Mass training of hands-only CPR is one of the ways to spread information and teach this skill. Need for expensive CPR mannequins are a limiting factor in conducting such mass training programmes. This study assessed the effectiveness of a low-cost CPR pillow model in training hands-only CPR. Methodology: Two hundred and six undergraduate students underwent a two-hour CPR training session. They were randomly divided into two groups – mannequin group and CPR pillow group and practiced hands-only CPR on a standard mannequin and a low-cost CPR pillow model, respectively. Knowledge, attitude, and skill acquisition were objectively assessed and compared between the two groups. Results: There was no statistical difference in hand positioning, chest compression rate and fraction, depth and overall CPR score between the two groups trained via mannequin and CPR Pillow (P > 0.05). The CPR pillow group had better percentage of chest recoil as compared to the mannequin group (86% vs 73%; P < 0.001). Conclusion: The use of low-cost homemade CPR devices such as our CPR pillow model is an acceptable alternative to mannequin for training hands-only CPR to lay rescuers.
