2019Co-Authors: Shota Tanaka, Kyoko Tsukigase, Takahiro Hara, Ryo Sagisaka, Helge Myklebust, Tonje S Birkenes, Hiroyuki Takahashi, Ayana Iwata, Yutaro Kidokoro, Momoyo YamadaAbstract:Objectives ‘Quality Cardiopulmonary Resuscitation (QCPR) Classroom’ was recently introduced to provide higher-Quality Cardiopulmonary Resuscitation (CPR) training. This study aimed to examine whether novel QCPR Classroom training can lead to higher chest-Compression Quality than standard CPR training. Design A cluster randomised controlled trial was conducted to compare standard CPR training (control) and QCPR Classroom (intervention). Setting Layperson CPR training in Japan. Participants Six hundred forty-two people aged over 15 years were recruited from among CPR trainees. Interventions CPR performance data were registered without feedback on instrumented Little Anne prototypes for 1 min pretraining and post-training. A large classroom was used in which QCPR Classroom participants could see their CPR performance on a big screen at the front; the control group only received instructor’s subjective feedback. Primary and secondary outcome measures The primary outcomes were Compression depth (mm), rate (Compressions per minute (cpm)), percentage of adequate depth (%) and recoil (%). Survey scores were a secondary outcome. The survey included participants’ confidence regarding CPR parameters and ease of understanding instructor feedback. Results In total, 259 and 238 people in the control and QCPR Classroom groups, respectively, were eligible for analysis. After training, the mean Compression depth and rate were 56.1±9.8 mm and 119.2±7.3 cpm in the control group and 59.5±7.9 mm and 116.8±5.5 cpm in the QCPR Classroom group. The QCPR Classroom group showed significantly more adequate depth than the control group (p=0.001). There were 39.0% (95% CI 33.8 to 44.2; p Conclusions QCPR Classroom helped students achieve high-Quality CPR training, especially for proper Compression depth and full recoil. For good educational achievement, a novel QCPR Classroom with a metronome sound is recommended.

25 effect of instructor s real time feedback using qcpr classroom device during layperson cardiopulmonary resuscitation cpr training on Quality of cpr performances a prospective cluster randomised trial
2018Co-Authors: Sy Kong, Sang Do Shin, Kyungjun Song, Ki Jeong Hong, Jung Ho Park, Tae Han Kim, Tonje S BirkenesAbstract:Aim The evidence supporting delivery of Quality cardiopulmonary resuscitation (CPR) is growing and significant attention has been focused on improving CPR education among laypersons perform bystander CPR. The aim of this randomised trial was to assess the effectiveness of instructor’s real-time objective feedback during CPR training compared to conventional feedback in terms of trainee’s CPR Quality. Method We performed a cluster randomised trial of community CPR training classes at Nowon District Health Community Centre in Seoul. CPR training classes were randomised into either intervention (instructor’s objective real-time feedback based on the QCPR Classroom device or control (conventional, instructor’s judgement-based feedback) group. Laerdal QCPR Classroom software is a real-time feedback device, which monitors Quality of real-time CPR performances of multiple trainees simultaneously. During each training session, trainees practiced CPR five times. The primary outcome was the total CPR score, which is an overall measure of chest Compression Quality. Secondary outcomes were individual CPR performance parameters, including average number of Compressions, average Compression depth, percent adequate depth and percent acceptable release. Generalised linear mixed models were used to analyse the outcome data, accounting for both cluster- (random effect) and individual-(fixed effect) level factors. : A total of 149 training sessions (2613 trainees) were randomised into 70 intervention (1262 trainees) and 79 control (1351 trainees) groups. During the training, trainees in the QCPR feedback group significantly increased overall CPR score performance compared with those in the conventional feedback group (model-based mean Δ increment from baseline to session 5: 11.2 (95% CI: 9.2 to 13.2) and 8.0 (6.0–9.9), respectively) with statistically significant between group difference (p=0.02). Individual parameters of Compression depth and release also showed higher improvement among trainees in QCPR group with marginal significance (p Results In this randomised trial, QCPR-Classroom based feedback during the CPR training session resulted in improved overall CPR Quality. In this randomised trial, QCPR-Classroom based feedback during the CPR training session resulted in improved overall CPR Quality. This suggests beneficial effect of instructor’s real-time objective feedback on the Quality of layperson’s CPR performance. Conclusion The training equipment used in this study (QCPR Classroom) was supported by the Laerdal Medical, but had no role in the design and conduct of the study; collection, management, analysis, and interpretation of the data.

Quality of chest Compressions during 10 min of single rescuer basic life support with different Compression ventilation ratios in a manikin model
2008Co-Authors: Conrad Arnfinn Bjorshol, Eldar Soreide, Tor Harald Torsteinbo, Kristian Lexow, Odd Bjarte Nilsen, Kjetil SundeAbstract:Summary Introduction Good Quality basic life support (BLS) improves outcome during cardiac arrest. As fatigue may reduce BLS performance over time we wanted to examine the Quality of chest Compressions in a single-rescuer scenario during prolonged BLS with different Compression:ventilation ratios (C:V ratios). Material and methods Professional paramedics were asked to perform single-rescuer BLS with C:V ratios of 15:2, 30:2 and 50:2 for 10 min each in random order. A Laerdal Medical Resusci Anne Simulator with PC Skillreporting System was used for BLS Quality analysis. Total number of chest Compressions, Compression depth and Compression rate were measured and the differences between the C:V ratios were analysed with repeated measures ANOVA. For analysis of fatigue, chest Compression variables for each 2-min period were analysed and compared with the first 2-min period using repeated measures ANOVA. Results Altogether 50 paramedics completed the study. The mean number of chest Compressions increased significantly from 604 to 770 and 862 with C:V ratios of 15:2, 30:2 and 50:2, respectively. Chest Compression rate was significantly higher with C:V ratio of 15:2 compared to 30:2 and 50:2 but was above 100 per minute for all three ratios. However, the mean chest Compression depth did not change significantly between the different C:V ratios. The number of chest Compressions did not change significantly with time for any of the three C:V ratios. Compression depth did decline after the first 2-min period for 30:2 and 50:2 as did Compression rate for all three ratios. However all were above the guideline limits for the entire test period. Conclusion Increasing the C:V ratio increases the number of chest Compressions during 10 min of BLS. Compression depth and Compression rate were within guideline recommendations for all three ratios. We found no decline in chest Compression Quality below guideline recommendations during 10 min of BLS with any of the three different C:V ratios.

haemodynamic effects of adrenaline epinephrine depend on chest Compression Quality during cardiopulmonary resuscitation in pigs
2006Co-Authors: Morten Pytte, Jo Kramerjohansen, Joar Eilevstjonn, Morten Eriksen, Taevje A Stromme, Kristin Godang, Lars Wik, Petter Andreas Steen, Kjetil SundeAbstract:Summary Background Adrenaline (epinephrine) is used during cardiopulmonary resuscitation (CPR) based on animal experiments without supportive clinical data. Clinically CPR was reported recently to have much poorer Quality than expected from international guidelines and what is generally done in laboratory experiments. We have studied the haemodynamic effects of adrenaline during CPR with good laboratory Quality and with Quality simulating clinical findings and the feasibility of monitoring these effects through VF waveform analysis. Methods and results After 4min of cardiac arrest, followed by 4min of basic life support, 14 pigs were randomised to ClinicalCPR (intermittent manual chest Compressions, Compression-to-ventilation ratio 15:2, Compression depth 30–38mm) or LabCPR (continuous mechanical chest Compressions, 12 ventilations/min, Compression depth 45mm). Adrenaline 0.02mg/kg was administered 30s thereafter. Plasma adrenaline concentration peaked earlier with LabCPR than with ClinicalCPR, median (range), 90 (30, 150) versus 150 (90, 270)s ( p =0.007), respectively. Coronary perfusion pressure (CPP) and cortical cerebral blood flow (CCBF) increased and femoral blood flow (FBF) decreased after adrenaline during LabCPR (mean differences (95% CI) CPP 17 (6, 29)mmHg ( p =0.01), FBF −5.0 (−8.8, −1.2) mlmin −1 ( p =0.02) and median difference CCBF 12% of baseline ( p =0.04)). There were no significant effects during ClinicalCPR (mean differences (95% CI) CPP 4.7 (−3.2, 13)mmHg ( p =0.2), FBF −0.2 (−4.6, 4.2)mlmin −1 ( p =0.9) and CCBF 3.6 (−1.8, 9.0)% of baseline ( p =0.15)). Slope VF waveform analysis reflected changes in CPP. Conclusion Adrenaline improved haemodynamics during laboratory Quality CPR in pigs, but not with Quality simulating clinically reported CPR performance.
