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.

Although the use of audio feedback with devices such as metronomes during cardiopulmonary resuscitation (CPR) is a simple method for improving CPR quality, its effect on the quality of pediatric CPR has not been adequately evaluated. In this study, 64 healthcare providers performed CPR (with one- and two-handed chest compression (OHCC and THCC, respectively)) on a pediatric resuscitation manikin (Resusci Junior QCPR), with and without audio feedback using a metronome (110 beats/min). CPR was performed on the floor, with a compression-to-ventilation ratio of 30:2. For both OHCC and THCC, the rate of achievement of an adequate compression rate during CPR was significantly higher when performed with metronome feedback than that without metronome feedback (CPR with vs. without feedback: 100.0% (99.0, 100.0) vs. 94.0% (69.0, 99.0), p < 0.001, for OHCC, and 100.0% (98.5, 100.0) vs. 91.0% (34.5, 98.5), p < 0.001, for THCC). However, the rate of achievement of adequate compression depth during the CPR performed was significantly higher without metronome feedback than that with metronome feedback (CPR with vs. without feedback: 95.0% (23.5, 99.5) vs. 98.5% (77.5, 100.0), p = 0.004, for OHCC, and 99.0% (95.5, 100.0) vs. 100.0% (99.0, 100.0), p = 0.003, for THCC). Although metronome feedback during pediatric CPR could increase the rate of achievement of adequate compression rates, it could cause decreased compression depth.

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)

AbstractObjectivesWe aimed to explore whether a) step stool use is associated with improved cardiopulmonary resuscitation (CPR) quality; b) provider adjusted height is associated with improved CPR quality; and if associations exist, c) determine whether just-in-time (JIT) CPR training and/or CPR visual feedback attenuates the effect of height and/or step stool use on CPR quality.MethodsWe analysed data from a trial of simulated cardiac arrests with three study arms: No intervention; CPR visual feedback; and JIT CPR training. Step stool use was voluntary. We explored the association between 1) step stool use and CPR quality, and 2) provider adjusted height and CPR quality. Adjusted height was defined as provider height + 23 cm (if step stool was used). Below-average height participants were ≤ gender-specific average height; the remainder were above average height. We assessed for interaction between study arm and both adjusted height and step stool use.ResultsOne hundred twenty-four subjects participated; 1,230 30-second epochs of CPR were analysed. Step stool use was associated with improved compression depth in below-average (female, p=0.007; male, p<0.001) and above-average (female, p=0.001; male, p<0.001) height providers. There is an association between adjusted height and compression depth (p<0.001). Visual feedback attenuated the effect of height (p=0.025) on compression depth; JIT training did not (p=0.918). Visual feedback and JIT training attenuated the effect of step stool use (p<0.001) on compression depth.ConclusionsStep stool use is associated with improved compression depth regardless of height. Increased provider height is associated with improved compression depth, with visual feedback attenuating the effects of height and step stool use.

Background: Also, it is well known that telephone-CPR (T-CPR) is effective to increase the rate of bystander CPR. However few reported suggested that T-CPR’ effective trough neurologically favorable outcome due to lack of adequate feedback. Purpose: The aim is this study is to identify the effective voice feedback during on T-CPR. Method: Twenty layperson without CPR training experience for at least 1 year were enrolled. They performed Hands-only CPR for 4 minutes followed by in 3 ways randomly. The first way is no feedback in the trial (non-FB Group). Second, they receive feedback in each 30 seconds (30sec-FB group). The third, they receive feedback in each 10 seconds (10sec-FB group) with enough interval time(30min) to restoration by fatigue, respectively. The feedback is simply telling by phone laypersons to push harder no matter how their compressions. Paired t-test were applied for statically analysis. Result: The average depth of 4 minutes through is 40.9±8.3mm with non-FB group, 43.8±6.5mm with 30sec-FB group, 47.8±5.9mm with 10sec-FB group, respectively. Statically significance were seen in non-FB groups and 30 sec-FB groups(P<.05) compared with 10sec-FB group. The compression depth decreasing by time in each group, however the decrease rate is higher in non-FB group than 10sec-FB group and 30sec-FB group(P<.05), respectively. Discussion: Chest compression depth in layperson is normally not enough. But the depth increased when they positive voice feedback. However they could keep better compressing for entire 2 minutes. Conclusion: The continuous feedback by phone is necessary to make layperson to perform quality chest compression. Further investigation warrant.

Objective: This study aimed to verify the effect of introducing a feedback device during adult and infant cardiopulmonary resuscitation training. Methods: A feedback device was introduced in the cardiopulmonary resuscitation training course of our medical school in the middle of the last semester. The cardiopulmonary resuscitation training course consisted of 2 h of instructor-led cardiopulmonary resuscitation training and 1 h of self-practice time. All students should complete the adult and infant cardiopulmonary resuscitation skill tests just after the course. Each test consisted of five cycles of single-rescuer cardiopulmonary resuscitation. A feedback device was introduced only in the self-practice session. The cardiopulmonary resuscitation parameters of the skill tests before ( n = 40) and after ( n = 39) introducing the feedback device were analysed. Results: The ratios of correct rate significantly increased after introducing the feedback device in both the skill tests (adult test: 58.5 ± 37.2 vs 85.5 ± 21.4, p = 0.001; infant test: 55.0 ± 32.4 vs 80.2 ± 20.7, p = 0.001). Although the average depths did not significantly differ between those before and after introducing the feedback device in the adult test (58.4 ± 4.0 mm vs 59.0 ± 3.7 mm, p = 0.341), it increased significantly after introducing the feedback device in the infant test (38.3 ± 4.3 mm vs 40.8 ± 1.1 mm, p = 0.001). Conclusion: Introducing a feedback device might have enhanced the accuracies of compression rate in adult and infant cardiopulmonary resuscitation training. However, the potential positive effect on chest compression depth was limited to infant cardiopulmonary resuscitation training.

The study was conducted to improve chest compression training by analyzing manikin-assessed scores on chest compression and self-assessed scores on cardiopulmonary resuscitation (CPR) based on music and metronome training after video self-instruction (VSI). The 64 participants had undertaken 50 min of VSI and practiced 25 min of compression-only (C-O) CPR. Thirty-two participants of the music (the Bee Gees’ Stayin’ Alive) training group practiced C-O CPR 103 times a min, while 32 participants of the metronome training group practiced C-O CPR at 100 times a min. Immediately after the training, participants performed 150 chest compressions on Resusci Anne SkillReporter; researchers collected 64 printouts, and 128 self-assessed scores on willingness, knowledge, performance, and attitude through pre and post-training questionnaires. There was no difference in the manikin-assessed scores between the music and metronome training groups. The two training methods were consistent with or similar to the compression guidelines. Therefore, C–O CPR training can be imparted by utilizing music as well as the existing metronome training method; however, supplementary research on how to maintain compression depth is needed, and ventilation training should be provided using other feedback devices.
