“…A recent study by Cheskes et al assessed the association between CCRV, the maximal velocity of chest compression release in the posterior to anterior direction, and clinical outcomes. 23 They found an association between CCRV and survival to hospital discharge in their univariate and categorical analyses, however there was no independent statistical association in their multivariable model. Importantly, CCRV and complete chest recoil are not synonymous.…”

“…CCRV was assessed as a categorical variable [fast (≥400 mm/s), moderate (300-399.9 mm/s), or slow (<300 mm/s)] as well as a continuous variable (mm/s). 23 Crude proportions were compared using Fisher's exact test. We analyzed the distribution of release velocities for chest compressions of individual OHCA cases to determine the appropriateness of using mean CCRV as a measure of CPR quality.…”

“…It should be noted that in our study the release velocity in all groups oscillated between 220 and 300 mm/s, corresponding in all cases with the slow velocity. However, the influence of CC release velocity and survival is still controversial because other studies have found no relationship between them 22 . More studies are needed to analyze the role of this parameter in the quality of resuscitation.…”

The main objetive was to compare 30:2 and 15:2 compression-to-ventilation ratio in two simulated pediatric cardiopulmonary resuscitation (cpR) models with single rescuer. the secondary aim was to analyze the errors or omissions made during resuscitation. A prospective randomized parallel controlled study comparing 15:2 and 30:2 ratio in two manikins (child and infant) was developed. The CPR was performed by volunteers who completed an basic CPR course. Each subject did 4 CPR sessions of 3 minutes each one. Depth and rate of chest compressions (CC) during resuscitation were measured using a Zoll Z series defibrillator. Visual assessment of resuscitation was performed by an external researcher. A total of 26 volunteers performed 104 CPR sessions. Between 54-62% and 44-53% of CC were performed with an optimal rate and depth, respectively, with no significant differences. No differences were found in depth or rate of CC between 15:2 and 30:2 compression-to-ventilation ratio with both manikins. In the assessment of compliance with the ERC CPR algorithm, 69.2-80.8% of the subjects made some errors or omissions during resuscitation, the most frequent was not asking for help and not giving rescue breaths. the conclusions were that a high percentage of cc were not performed with optimal depth and rate. errors or omissions were frequently made by rescuers during resuscitation.Pediatric cardiac arrest (CA) is an important health problem since it has high mortality (52-80%) and a large proportion of survivors suffer from permanent and severe neurologic disability (poor outcome in 20-50%) 1-4 . Previous studies have shown that optimizing maneuvers of cardiopulmonary resuscitation (CPR) in children could improve survival and prognosis 4,5 . Nevertheless, many studies documented that CPR is often not optimally performed 6,7 .The 2015 European Resuscitation Council (ERC) guidelines recommend a synchronized 15:2 compression-to-ventilation ratio during basic pediatric CPR 1,8,9 . However, there is not a strong evidence to indicate the best compression-to-ventilation ratio in pediatric CPR 10,11 . Firstly, maintaining an adequate ventilation is crucial during CPR in children because pediatric CA is primarily caused by respiratory failure 2 . The 15:2 ratio delivers more ventilations whereas the 30:2 ratio delivers more chest compressions (CC). In the other hand, different recommendations for the compression-to-ventilation ratio between children (15:2 ratio) and adults (30:2 ratio) could increase the errors or omissions and impair learning. In adult simulation models 12-14 , there are different studies that compare the quality of CC in both compression-to-ventilation ratio. However, only one study conducted in pediatric models, but it was developed by volunteers with pediatric advanced life support (PALS) accreditation 15 . In our knowledge, there are no previous studies comparing the quality of CC between 15:2 and 30:2 compression-to-ventilation ratio during pediatric CPR conducted by volunteers training in basic life support.with ...

“…The force sensor is relatively larger and more expensive than an accelerometer. The challenges in the direct measurement of leaning or recoil result in the use of indirect measurements, such as CCRV calculated from the accelerometry signal, to assess the performance of chest recoil [13][14][15][16] . An improved survival and favourable neurologic outcomes from hospital discharge after OHCA had been documented 14,15 .…”

The one month survival rate after out-of-hospital cardiac arrest (OHCA) in the paediatric population remains low. Improving survival in paediatric OHCA by enhancing the quality of cardiopulmonary resuscitation (CPR) is important. In this study, we aimed to analyse the factors associated with CPR quality by using a real-time feedback device. Participants were prospectively divided into 4 groups: paediatric research fellows, paediatric residents, medical students (clerks), and paediatric critical care nurses. Then, the participants were asked to perform 5 cycles of CPR on a paediatric simulation manikin without prompts from feedback devices, and to repeat another 5 cycles of CPR after education with the 2015 paediatric advanced life support guidelines. A total of 75 participants were evaluated. In the overall analysis, an improvement in the percentage of participants meeting the target compression rate was observed (from 49.82% to 71.23%, P < 0.001). The percentage of participants achieving the target compression depth improved from 73.77% to 85.63% (P = 0.005). Among the 4 groups, the residents showed the most significant improvement in both compression rate (from 48.41% to 86.57%, P < 0.001) and compression depth (from 63.50% to 95.57%, P < 0.001). Inappropriate rate was a more important factor resulting in inadequate CPR performance than inappropriate depth. An excessive compression rate was also a common problem. In conclusions, the real-time CPR feedback device may help clinical physicians and nurses in improving the quality of chest compression. Excessive CPR compression rate may be a major cause of inadequate CPR performance.
