“…A p-value < 0.05 was defined as statistically significant. The sample size calculation was based on the comparison of the primary end point in the three groups; we did not perform earlier studies that would have been useful as a basis for a sample size calculation; therefore, based on previous studies, [36][37][38] we wanted to adequately detect a mean paired difference of 0.7 times the standard deviation. Based on an alpha = 0.05 and a power of 80%, a sample size of 37 study participants per group was needed.…”

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...

“…It is becoming increasingly recognised that survival is affected not only by whether CPR is performed, but also by its quality. Recent evidence has confirmed the importance of chest compression depth [4][5], rate [6], releasing pressure between compressions [7], minimising interruptions in CPR [8], avoiding pauses prior to defibrillation [9] and not hyperventilating the patient [10] to ensure the optimal effectiveness of resuscitation. Despite the knowledge that the quality of CPR is of critical importance to outcomes, studies consistently demonstrate that the quality of CPR performed in real life by both laypersons [11] and healthcare providers [12][13][14] is frequently sub-optimal.…”

Purpose of review:It is recognised that the quality of CPR is an important predictor of outcome from cardiac arrest yet studies consistently demonstrate that the quality of CPR performed in real life is frequently sub-optimal. Mechanical chest compression devices provide an alternative to manual CPR. This review will consider the evidence and current indications for the use of these devices. Recent findings:Physiological and animal data suggest that mechanical chest compression devices are more effective than manual CPR. However there is no high quality evidence showing improved outcomes in humans. There are specific circumstances where it may not be possible to perform manual CPR effectively e.g. during ambulance transport to hospital, en-route to and during cardiac catheterisation, prior to organ donation and during diagnostic imaging where using these devices may be advantageous. Summary:There is insufficient evidence to recommend the routine use of mechanical chest compression devices. There may be specific circumstances when CPR is difficult or impossible where

“…The recommended chest compression depth is now at least 2 inches on the basis of studies that demonstrated improved defibrillation success and short-term outcomes with increased compression depth, and the recommended compression rate is at least 100 per minute. 16,24,25 In addition to guideline changes, public education and CPR training are paramount because laypersons trained in CPR are significantly more likely to perform CPR. 26 …”

“…Two alternate studies examining real-time feedback, one of which used the addition of weekly debriefing, both improved the quality of CPR and demonstrated better short-term outcomes. 25,41 Laypersons not trained in CPR may be able to provide effective CPR with assistance from emergency medical system (EMS) dispatchers. Dispatch-assisted CPR has been demonstrated to be safe and to increase the rates of bystander CPR and may improve survival from cardiac arrest.…”
