Long-term benefits of chest compression-only cardiopulmonary resuscitation training using real-time visual feedback manikins: a randomized simulation study

AbstractIntroduction:Recent cardiopulmonary resuscitation (CPR) guidelines recommend the use of CPR prompt/feedback devices during CPR training because it can improve the quality of CPR.Problem:Chest compression depth and full chest recoil show a trade-off relationship. Therefore, achievement of both targets (adequate chest compression depth and full chest recoil) simultaneously is a difficult task for CPR instructors. This study hypothesized that introducing a visual feedback device to the CPR training could improve the chest compression depth and ratio of full chest recoil simultaneously.Methods:The study investigated the effects of introducing a visual feedback device during CPR training by comparing the results of skill tests before and after introducing a visual feedback device. The results of skill tests from 2016 through 2018 were retrospectively reviewed. The strategy of emphasizing chest compression depth was implemented during the CPR training in 2017, and a visual feedback device was introduced in 2018. The interval between the CPR training and skill tests was seven days. Feedback was not provided during the skill tests.Results:In total, 159 students completed skill tests. Although the chest compression depth increased significantly from 50 mm (42–54) to 60 mm (59–61) after emphasizing chest compression depth (P < .001), the ratio of full chest recoil decreased simultaneously from 100% (100–100) to 81% (39–98; P < .001). The ratio of full chest recoil increased significantly from 81% (39–98) to 95% (77–100) after introducing a visual feedback device (P = .018). However, the students who did not achieve 80% of the ratio of full chest recoil remained significantly higher than in 2016 (1% in 2016, 49% in 2017, and 27% in 2018; P < .001).Conclusions:Although introducing a visual feedback device during CPR training resulted in increasing the ratio of full chest recoil while maintaining the adequacy of chest compression depth, 27% of the students still did not achieve 80% of the ratio of full chest recoil. Another educational strategy should be considered to increase the qualities of CPR more completely.

Introduction The aim of this study was to determine the effect of hand positioning on the quality of external chest compression (ECC) by novice rescuers. Methods This observational simulation study was conducted for 117 included participants. After completion of an adult cardiopulmonary resuscitation (CPR) training program for 3-h, the participants selected which of their hands would be in contact with the mannequin during ECC and performed 5 cycles of single rescuer CPR on a recording mannequin. The participants were assigned to 2 groups: the dominant hand group (DH; n=40) and the non-dominant hand group (NH; n=29). The depth and rate of ECC were analysed to compare the effectiveness of ECC between 2 groups. Results The rate of ECC was significantly faster in the DH group (mean, 117.3 ±11.4/min) than in the NH group (mean, 110.9±12.2/min) (p=0.028). However, the depth of ECC in the dominant hand group (mean, 52.4±5.9 mm) was not significantly different from that in the non-dominant hand group (mean, 50.8±6.0 mm) (p=0.287). Similarly, the portion of ECC with inadequate depth in the dominant hand group (mean, 1.8±4.3%) was not significantly different from that in the non-dominant hand group (mean, 5.3±15.6%) (p=0.252). Conclusions ECC can be performed with an acceptably higher rate of compressions when the dominant hand of the novice rescuer is placed in contact with the sternum. However, the position of the dominant hand does not affect the depth of ECC. (Hong Kong j.emerg.med. 2014;21:382-386)

Background: The evidence supporting delivery of quality cardiopulmonary resuscitation is growing and significant attention has been focused on improving bystander cardiopulmonary resuscitation education for laypeople. The aim of this randomized trial was to assess the effectiveness of instructor’s real-time objective feedback during cardiopulmonary resuscitation training compared to conventional feedback in terms of trainee’s cardiopulmonary resuscitation quality. Methods: We performed a cluster-randomized trial of community cardiopulmonary resuscitation training classes at Nowon District Health Community Center in Seoul. Cardiopulmonary resuscitation training classes were randomized into either intervention (instructor’s objective real-time feedback based on the QCPR Classroom device) or control (conventional, instructor’s judgment-based feedback) group. The primary outcome was total cardiopulmonary resuscitation score, which is an overall measure of chest compression quality. Secondary outcomes were individual cardiopulmonary resuscitation performance parameters, including compression rate, depth, and release. Generalized linear mixed models were used to analyze the outcome data, accounting for both random and fixed effects. Results: A total of 149 training sessions (2613 trainees) were randomized into 70 intervention (1262 trainees) and 79 control (1351 trainees) groups. Trainees in the QCPR feedback group significantly increased overall cardiopulmonary resuscitation score performance compared with those in the conventional feedback group (model-based mean Δ increment from baseline to session 5: 11.2 (95% confidence interval 9.2–13.2) and 8.0 (6.0–9.9), respectively; p = 0.02). Individual parameters of compression depth and release also showed higher improvement among trainees in QCPR group with positive trends (p < 0.08 for both). Conclusion: This randomized trial suggests beneficial effect of instructor’s real-time objective feedback on the quality of layperson’s cardiopulmonary resuscitation performance.
