“…Nonetheless, it has been proved that high-quality CPR improves the survival rate of cardiac arrest victims, 7 and that training of health care providers with feedback devices improves survival rates after OHCA. 23,24 We can therefore assume that better training of laypersons using feedback devices may positively affect survival rates after OHCA.…”

“…With better implementation of the links of this chain, cardiac arrest survival can be improved. 6 Early and high quality cardiopulmonary resuscitation (CPR) has been shown to greatly improve the survival rate of cardiac arrest victims, 7,8 as indicated by American Heart Association (AHA) guidelines changes from 2005 to date. [9][10][11] For this reason, the 2015 Guidelines for Cardiopulmonary Resuscitation stress the importance of performing high quality CPR immediately after a cardiac arrest.…”

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 the other (NF v. LF, p = 0.022; NF v. SF, p = 0.005). This improvement was also present in the percentage of compressions with a complete chest recoil (71.7% in NF, 86.6% in SF, and 88.8% in LF; p < 0.001), compressions with the correct hand position (93.2% in NF, 98.2% in SF, and 99.3% in LF; p < 0.001), and in the Total CPR Score (79.4% in NF, 90.2% in SF, and 92.5% in LF; p < 0.001). There were no significant differences for all of the parameters between group SF and group LF. Conclusions: Real-time visual feedback improves laypersons' CPR quality, and we suggest its use in every BLS/AED course for laypersons because it can help achieve the goals emphasized by the International Liaison Committee on Resuscitation recommendations. RÉSUMÉObjectif: Les chances de survie à la suite d'un arrêt cardiaque survenu dans la collectivité dépend de la rapidité des manoeuvres de réanimation cardiorespiratoire (RCR) ainsi que de leur qualité. L'étude décrite ici visait à vérifier si l'utilisation de dispositifs de rétroaction durant la formation des profanes en la matière pouvait améliorer la qualité des compressions thoraciques. Méthode: Ont participé à des cours de réanimation de base et de défibrillation 450 profanes en la matière, divisés au hasard en trois groupes : le premier a suivi le cours sans rétroaction (SR) aucune; le deuxième a suivi le cours avec une brève rétroaction (BR), soit 1 minute de formation avec une rétroaction visuelle en temps réel; et le troisième a suivi le cours avec une longue rétroaction (LR), soit 10 minutes de formation avec une rétroaction visuelle en temps réel. À la fin de chacun des cours, il y a eu enregistrement des compressions seules durant 1 min. Le principal critère d'évaluation était les différences de pourcentage quant aux compressions réalisées à la bonne profondeur. Résultats: Une amélioration sensible du pourcentage des compressions réalisées à la bonne profondeur a été observée dans les groupes dans lesquels il y avait eu de la rétroaction comparativement à celui qui n'en avait pas reç...

“…Since the 2000s, various important evidence on bystander interventions as well as procedures by emergency medical service (EMS) personnel at prehospital settings have been provided by the large‐scale Utstein‐based OHCA registries in Japan, such as the SOS‐KANTO Study,3 Utstein Osaka Project,4 and All‐Japan Utstein Registry 5…”

AimTo describe the registry design of the Japanese Association for Acute Medicine – out‐of‐hospital cardiac arrest (JAAM‐OHCA) Registry as well as its profile on hospital information, patient and emergency medical service characteristics, and in‐hospital procedures and outcomes among patients with OHCA who were transported to the participating institutions.MethodsThe special committee aiming to improve the survival after OHCA by providing evidence‐based therapeutic strategies and emergency medical systems from the JAAM has launched a multicenter, prospective registry that enrolled OHCA patients who were transported to critical care medical centers or hospitals with an emergency care department. The primary outcome was a favorable neurological status 1 month after OHCA.ResultsBetween June 2014 and December 2015, a total of 12,024 eligible patients with OHCA were registered in 73 participating institutions. The mean age of the patients was 69.2 years, and 61.0% of them were male. The first documented shockable rhythm on arrival of emergency medical services was 9.0%. After hospital arrival, 9.4% underwent defibrillation, 68.9% tracheal intubation, 3.7% extracorporeal cardiopulmonary resuscitation, 3.0% intra‐aortic balloon pumping, 6.4% coronary angiography, 3.0% percutaneous coronary intervention, 6.4% targeted temperature management, and 81.1% adrenaline administration. The proportion of cerebral performance category 1 or 2 at 1 month after OHCA was 3.9% among adult patients and 5.5% among pediatric patients.ConclusionsThe special committee of the JAAM launched the JAAM‐OHCA Registry in June 2014 and continuously gathers data on OHCA patients. This registry can provide valuable information to establish appropriate therapeutic strategies for OHCA patients in the near future.

“…Cardiopulmonary resuscitation (CPR) contributes to survival from cardiac arrest, especially when initiated early, including by non-professional volunteer responders with limited training [1,2]. Key characteristics of highquality CPR include a rate between 100 to 120 cpm, depth of 2-2.4 inches and complete chest wall recoil [3].…”
