ABSTRACT=Background: The most recent international guidelines recommended support training of chest compression (CC) using feedback devices. The aim of this study was to compare the training efficacy of a simplified feedback trainer with the traditional cardiopulmonary resuscitation (CPR) simulator in CPR training.
Methods: A total of 60 soldiers were randomly allocated into three groups equally, trained with a simplified external cardiac massage (ECM) trainer named Soul SheathTM (SS) (SS group), a Resusci Anne manikin (RA group) or traditional simulation training with instructor feedback, respectively. After 7 days of training, the CPR skills were tested blindly in a 2-min assessment session. The primary outcome was the proportion of effective CC, and the secondary outcome included CC rate, depth, compression position and extent of release. Results: The percentage of effective CC achieved in the SS group was comparable to RA group (77.0±15.52 vs. 77.5±10.73%, p=0.922), and significantly higher than that in the control group (77.0±15.52 vs. 66.8±16.87%, p=0.037). Both of the SS and RA groups showed better CC performance than the control group in terms of CC rate (SS group vs. control group, P=0.032, and RA group vs. control group, P=0.026), proportion of shallow CC (SS group vs. control group, P=0.011, and RA group vs. control group, P=0.017). No difference between the SS group and RA group was found in all CC parameters. 
Conclusions: The simplified ECM trainer (SS) provides a similar efficacy to the traditional manikin simulator with feedback in CC training to improve the quality of CPR skills.
