This study aims to contribute to the scarce data available about the abilities of untrained lay persons to perform hands-only cardio-pulmonary resuscitation (CPR) on a manikin and the improvement of their skills during training with an autonomous CPR feedback device. The study focuses on the following questions: (i) Is there a need for such a CPR training device? (ii) How adequate are the embedded visual feedback and audio guidance for training of lay persons who learn and correct themselves in real time without instructor guidance? (iii) What is the achieved effect of only 3 min of training? This is a prospective study in which 63 lay persons (volunteers) received a debriefing to basic life support and then performed two consecutive 3 min trials of hands-only CPR on a manikin. The pre-training skills of the lay persons were tested in trial 1. The training process with audio guidance and visual feedback from a cardio compression control device (CC-Device) was recorded in trial 2. After initial debriefing for correct chest compressions (CC) with rate 85-115 min-1, depth 3.8-5.4 cm and complete recoil, in trial 1 the lay persons were able to perform CC without feedback at mean rate 95.9 ± 18.9 min-1, mean depth 4.13 ± 1.5 cm, with low proportions of 'correct depth', 'correct rate' and 'correct recoil' at 33%, 43%, 87%, resulting in the scarce proportion of 14% for compressions, which simultaneously fulfill the three quality criteria ('correct all'). In trial 2, the training process by the CC-Device was established by the significant improvement of the CC skills until the 60th second of training, when 'correct depth', 'correct rate' and 'correct recoil' attained the plateau of the highest quality at 82%, 90%, 96%, respectively, resulting in 73% 'correct all' compressions within 3 min of training. The training was associated with reduced variance of the mean rate 102.4 ± 4.7 min-1 and mean depth 4.3 ± 0.4 cm, indicating a steady CC performance achieved among all trained participants. Multivariable linear regression showed that the compression depth, rate and complete chest recoil did not strongly depend on lay person age, gender, height, weight in pre-training and training stage (correlation coefficient below 0.54). The study confirmed the need for developing CPR abilities in untrained lay persons via training by real-time feedback from the instructor or CC-Device. The CC-Device embedded feedback was shown to be comprehensible and easy to be followed and interpreted. The high quality of the CC-Device-assisted training process of lay persons was confirmed. Thus learning or refresher courses in basic life support could be organized for more people trained at the same time with fewer instructors needed only for the initial debriefing and presentation of the CC-Device.
Real-Time Audiovisual Feedback Training Improves Cardiopulmonary Resuscitation Performance
Simulation in healthcare : journal of the Society for Simulation in Healthcare, 2019
The aim of the study was to quantitatively measure the effect of teaching cardiopulmonary resuscitation (CPR) using a real-time audiovisual feedback manikin system on first-year medical student's CPR performance. Methods: This is a prospective, manikin-based intervention study, including 2 consecutive classes of medical school students enlisted to a mandatory first aid course. One class (control group) was taught using manikin-based standard CPR education models. The second class (intervention group) was taught similarly, but with the addition of real-time CPR quality feedback provided by the manikins. Students' performance was assessed using a standardized Objective Structured Clinical Examination scenario, during which no real-time feedback was provided. Critical CPR parameters were measured including compression depth, chest recoil, ventilation volume, and "hands-off" time. Results: A total of 201 participants were included in the study, 106 in the control group and 95 in the intervention group. Baseline demographic characteristics and previous medical knowledge were similar for the 2 groups. A significant improvement was observed for all primary study outcomes in favor of the real-time feedback group for median (interquartile range) chest compression fraction [57 (52.75%-60%) vs. 49 (43%-55%), P < 0.001], compressions with adequate depth [66.5 (19.5%-95.25%) vs. 0 (0%-12%), P < 0.001], ventilations with adequate volume [68.5 (33%-89%) vs. 37 (0%-70%), P < 0.00], and a simulator-derived composite "total CPR score" [39 (24%-61.25%) vs. 13 (3.5%-22%), P < 0.001]. In multiple regression analysis, the real-time feedback group's performance was significantly better than the control group in all primary outcomes, adjusting for participant's characteristics of age, sex, and body mass index. Conclusions: The use of audiovisual feedback techniques to teach CPR improves skill acquisition with significant improvement in crucial prognosis-improving parameters, as tested in a "no-feedback" test scenario.

Objective The chances of surviving an out-of-hospital cardiac arrest depend on early and high-quality cardiopulmonary resuscitation (CPR). Our aim is to verify whether the use of feedback devices during laypersons’ CPR training improves chest compression quality. Methods Laypersons totalling 450 participating in Basic Life Support and Automated External Defibrillation (BLS/AED) courses were randomly divided into three groups: group No Feedback (NF) attended a course without any feedback, group Short Feedback (SF) a course with 1-minute training with real-time visual feedback, and group Long Feedback (LF) a course with 10-minute training with real-time visual feedback. At the end of each course, we recorded 1 minute of compression-only CPR. The primary end point was the difference in the percentage of compressions performed with correct depth. Results There was a significant improvement in the percentage of compressions with correct depth in the groups receiving feedback compared to ...

Background: Good quality basic life support (BLS) improves outcome following cardiac arrest. As BLS performance deteriorates over time we performed a parallel group, superiority study to investigate the effect of feedback on quality of chest compression with the hypothesis that feedback delays deterioration of quality of compressions. Methods: Participants attending a national one-day conference on cardiac arrest and CPR in Denmark were randomized to perform single-rescuer BLS with (n = 26) or without verbal and visual feedback (n = 28) on a manikin using a ZOLL AED plus. Data were analyzed using Rescuenet Code Review. Blinding of participants was not possible, but allocation concealment was performed. Primary outcome was the proportion of delivered compressions within target depth compared over a 2-minute period within the groups and between the groups. Secondary outcome was the proportion of delivered compressions within target rate compared over a 2-minute period within the groups and between the groups. Performance variables for 30-second intervals were analyzed and compared.

Context: Automated verbal and visual feedback improves quality of resuscitation in out-of-hospital cardiac arrest and was proven to increase short-term survival. Quality of resuscitation may be hampered in more difficult situations like emergency transportation. Currently there is no evidence if feedback devices can improve resuscitation quality during different modes of transportation. Objective: To assess the effect of real time automated feedback on the quality of resuscitation in an emergency transportation setting. Design: Randomised cross-over trial. Setting: Medical University of Vienna, Vienna Municipal Ambulance Service and Helicopter Emergency Medical Service Unit (Christophorus Flugrettungsverein) in September 2007. Participants: European Resuscitation Council (ERC) certified health care professionals performing CPR in a flying helicopter and in a moving ambulance vehicle on a manikin with human-like chest properties. Interventions: CPR sessions, with real time automated feedback as the intervention and standard CPR without feedback as control. Main outcome measures: Quality of chest compression during resuscitation.

Background: Many feedback devices have been designed to improve the resuscitation outcomes. None have been implemented as a standard in patient care. Objectives: The aim of this study was to evaluate the chest compression depth and rate during cardiopulmonary resuscitation with and without a feedback device and to evaluate differences regarding the impact of a feedback device based on provider experience. Methods: The study was performed on 20 men divided into two groups: group A (n = 10)—paramedics; group B (n = 10)—non-paramedics, trained to provide resuscitation. Participants were examined during resuscitation with Ambu Megacode manikin and with or without the feedback device—CPRmeter. Depth of compressions was evaluated in the first and fourth minute of resuscitation with a BTS Smart DX7000 motion capture system. For statistical analysis, summary statistics, Shapiro–Wilk Test of normality, dependent samples t-test, Levene test, t-test for independent samples, or Welch’s t-test w...
Do automated real-time feedback devices improve CPR quality? A systematic review of literature
Resuscitation Plus, 2021
Aim: Automated real-time feedback devices have been considered a potential tool to improve the quality of cardiopulmonary resuscitation (CPR). Despite previous studies supporting the usefulness of such devices during training, others have conflicting conclusions regarding its efficacy during reallife CPR. This systematic review aimed to assess the effectiveness of automated real-time feedback devices for improving CPR performance during training, simulation and real-life resuscitation attempts in the adult and paediatric population. Methods: Articles published between January 2010 and November 2020 were searched from BVS, Cinahl, Cochrane, PubMed and Web of Science, and reviewed according to a pre-defined set of eligibility criteria which included healthcare providers and randomised controlled trial studies. CPR quality was assessed based on guideline compliance for chest compression rate, chest compression depth and residual leaning. Results: The selection strategy led to 19 eligible studies, 16 in training/simulation and three in real-life CPR. Feedback devices during training and/or simulation resulted in improved acquisition of skills and enhanced performance in 15 studies. One study resulted in no significant improvement. During real resuscitation attempts, three studies demonstrated significant improvement with the use of feedback devices in comparison with standard CPR (without feedback device). Conclusion: The use of automated real-time feedback devices enhances skill acquisition and CPR performance during training of healthcare professionals. Further research is needed to better understand the role of feedback devices in clinical setting.

IMPORTANCE The quality of cardiopulmonary resuscitation (CPR) affects hemodynamics, survival, and neurological outcomes following pediatric cardiopulmonary arrest (CPA). Most health care professionals fail to perform CPR within established American Heart Association guidelines. OBJECTIVE To determine whether "just-in-time" (JIT) CPR training with visual feedback (VisF) before CPA or real-time VisF during CPA improves the quality of chest compressions (CCs) during simulated CPA. DESIGN, SETTING, AND PARTICIPANTS Prospective, randomized, 2 × 2 factorial-design trial with explicit methods (July 1, 2012, to April 15, 2014) at 10 International Network for Simulation-Based Pediatric Innovation, Research, & Education (INSPIRE) institutions running a standardized simulated CPA scenario, including 324 CPR-certified health care professionals assigned to 3-person resuscitation teams (108 teams). INTERVENTIONS Each team was randomized to 1 of 4 permutations, including JIT training vs no JIT training before CPA and real-time VisF vs no real-time VisF during simulated CPA. MAIN OUTCOMES AND MEASURES The proportion of CCs with depth exceeding 50 mm, the proportion of CPR time with a CC rate of 100 to 120 per minute, and CC fraction (percentage CPR time) during simulated CPA. RESULTS The quality of CPR was poor in the control group, with 12.7% (95% CI, 5.2%-20.1%) mean depth compliance and 27.1% (95% CI, 14.2%-40.1%) mean rate compliance. JIT training compared with no JIT training improved depth compliance by 19.9% (95% CI, 11.1%-28.7%; P < .001) and rate compliance by 12.0% (95% CI, 0.8%-23.2%; P = .037). Visual feedback compared with no VisF improved depth compliance by 15.4% (95% CI, 6.6%-24.2%; P = .001) and rate compliance by 40.1% (95% CI, 28.8%-51.3%; P < .001). Neither intervention had a statistically significant effect on CC fraction, which was excellent (>89.0%) in all groups. Combining both interventions showed the highest compliance with American Heart Association guidelines but was not significantly better than either intervention in isolation. CONCLUSIONS AND RELEVANCE The quality of CPR provided by health care professionals is poor. Using novel and practical technology, JIT training before CPA or real-time VisF during CPA, alone or in combination, improves compliance with American Heart Association guidelines for CPR that are associated with better outcomes.

High quality cardiopulmonary resuscitation (CPR) is imperative to improve patient outcome after a cardiac arrest. However, it has been demonstrated that CPR quality is normally of suboptimal quality in both real-life resuscitation attempts or simulated training. Automated real-time feedback (ARTF) devices have been considered a potential tool to improve the quality of CPR and maximise retention of the skills. Although previous studies have supported the usefulness of such devices during training, others have conflicting conclusions with regards to its efficacy during real-life CPR. This systematic review of the literature aims to assess the effectiveness of ARTF for improving CPR performance during simulated training and real-life resuscitation in the adult and paediatric population. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines [1], articles published between January 2010 and November 2019 were searched from 7 electronic databases ...
