Abstract Background The influence of past familial experiences of receiving cardiopulmonary resuscitation (CPR) and medical help in various cardiac arrest and nonfatal cardiac events toward willingness to “pay it forward” by helping the next cardiac arrest victim was explored. Methods Using a validated questionnaire, 6248 participants were asked to rate their willingness to perform bystander chest compression with mouth-to-mouth ventilation and chest compression-only CPR. Their past familial experiences of receiving cardiopulmonary resuscitation (CPR) and medical help in various cardiac arrest and nonfatal cardiac events were also recorded. Results Kruskal-Wallis test with post hoc Dunn’s pairwise comparisons showed that the following were significantly more willing to perform CPR with mouth-to-mouth ventilation: familial experience of “nonfatal cardiac events” (mean rank = 447) vs “out-of-hospital cardiac arrest with no CPR” (mean rank = 177), U = 35442.5, z = −2.055, p = 0.04; “in-hospital cardiac arrest and successful CPR” (mean rank = 2955.79) vs “none of these experiences” (mean rank = 2468.38), U = 111903, z = −2.60, p = 0.01; and “in-hospital cardiac arrest with successful CPR” (mean rank = 133.45) vs “out-of-hospital arrest with no CPR” (mean rank = 112.36), U = 4135.5, z = −2.06, p = 0.04. For compression-only CPR, Kruskal-Wallis test with multiple runs of Mann-Whitney U tests showed that “nonfatal cardiac events” group was statistically higher than the group with “none of these experiences” (mean rank = 3061.43 vs 2859.91), U = 1194658, z = −2.588, p = 0.01. The groups of “in-hospital cardiac arrest with successful CPR” and “in-hospital cardiac arrest with transient return of spontaneous circulation” were the most willing groups to perform compression-only CPR. Conclusion Prior familial experiences of receiving CPR and medical help, particularly among those with successful outcomes in a hospital setting, seem to increase the willingness to perform bystander CPR.

Objective: In cardiac arrest cases, high quality cardiopulmonary resuscitation and effective chest compression are vital issues in improving survival with good neurological outcomes. In this study, we investigated the effect of mechanical chest compression devices on 30- day survival in out-of-hospital cardiac arrest. Materials and Methods: This retrospective case-control study was performed on patients who were over 18 years of age and admitted to the emergency department for cardiac arrest between January 1, 2016 and January 15, 2018. Manual chest compression was performed to the patients before January 15, 2017, and mechanical chest compression was performed after this date. Return of spontaneous circulation, hospital discharge, and 30-day survival rates were compared between the groups of patients in terms of chest compression type. In this study, the LUCAS-2 model piston-based mechanical chest compression device was used for mechanical chest compressions. Results: The rate of return of spontaneous circulation was significantly lower in the mechanical chest compression group (11.1% vs 33.1%; p < 0.001). The 30-day survival rate was higher in the manual chest compression group (6.8% vs 3.7%); however, this difference was not statistically significant (p = 0.542). Furthermore, 30-day survival was 0% in the trauma group and 0.6% in the patient group who underwent cardiopulmonary resuscitation for over 20 minutes. Conclusion: It can be seen that the effect of mechanical chest compression on survival is controversial; studies on this issue should continue and, furthermore, studies on the contribution of mechanical chest compression on labor loss should be conducted.

Background: The international consensus on cardiopulmonary resuscitation (CPR) and emergency cardiovascular care science with treatment recommendations (CoSTR) 2010 changed the dispatcher-initiated telephone CPR instruction. Major changes of the telephone CPR instruction were simplified algorithm, elimination of “Look, listen, and feel for breathing” chest compressions first (C-A-B), chest compression only CPR if bystander was not trained in CPR, et al. However, few studies have investigated the efficacy of telephone CPR instruction based on the CoSTR 2010. Methods: From the All-Japan Utstein Registry for out-of-hospital cardiac arrest (OHCA) between 2006 and 2015, we enrolled adult (18 years or older) patients with bystander-witnessed OHCA and stratified by the two CoSTR eras (the CoSTR 2010 group from 2011 through 2015 versus the CoSTR 2005 group from 2006 through 2010). The primary endpoint was 30-day favorable neurological outcome after OHCA. Results: Of the 378,757 adult patients with bystander-witnessed OHCA, 199,117 (52.5%) received CPR based on the CoSTR 2010 and 179,640 (47.4%) received CPR based on the CoSTR 2005. In the whole cohort, the CoSTR 2010 group had higher proportion of cases receiving telephone CPR instruction than the CoSTR 2005 group (48.8% versus 40.9%, P<0.001). In the subgroups of patients receiving telephone CPR instruction, the CoSTR 2010 group had higher proportion of bystander chest compression-only CPR (60.5% versus 47.3%, p<0.001) and public access defibrillation (1.9% versus 0.9%, P<0.001) than the CoSTR 2005 group. Although those subgroups had similar proportion of initial shockable cardiac arrest rhythm (15.2 % in the CoSTR 2010 group versus 15.3 % in the CoSTR 2005 group, P=0.63), the CoSTR 2010 group had higher frequency of the favorable neurological outcome than the CoSTR 2005 group (4.5 % versus 3.7%%, P<0.001). In the subgroup of patients receiving telephone CPR instruction, an adjusted odds ratio for the favorable neurological outcome in the CoSTR 2010 group (reference, the CoSTR 2005 group) was 1.47 (95 % CI, 1.43-1.51, p<0.001). Conclusions: Telephone CPR instruction based on the CoSTR 2010 was the preferable approach to resuscitation for adult patients with bystander-witnessed OHCA.

Purpose: Survival rates after non-shockable out-of-hospital cardiac arrest (OHCA) remain low despite advances in resuscitation. Cardiopulmonary resuscitation (CPR) process measures may inform treatment strategies. We hypothesized that CPR process measures would be associated with return of spontaneous circulation (ROSC) and patient electrocardiogram (ECG) transitions. Methods: We obtained defibrillator monitor data for emergency medical service (EMS)-treated non-shockable OHCA from the Resuscitation Outcomes Consortium (ROC), an OHCA research network (U.S./Canada). We extracted ECG data from EMS defibrillator files and parsed cases into compression-free analyzable segments using custom MATLAB software. Two data abstractors classified segment rhythms as PEA, asystole, ventricular fibrillation (VF), pulseless ventricular tachycardia (PVT), or ROSC. We calculated CPR process measures (average rate, depth, duration, leaning proportion, chest compression fraction, and duty cycle) for CPR bouts preceding every ECG segment. We used mixed effects models controlling for subject to test associations between individual CPR process measures and the bout-level outcomes ROSC and shockable rhythm. Results: We analyzed 1893 cases consisting of 7981 CPR bouts. Case initial rhythms were asystole (68.2%), PEA (24.9%), or NSA-AED (6.9%). Segment rhythm classifications were asystole (78.1%), PEA (20.4%), ROSC (5.5%), VF (1.4%), and PVT (0.07%). Regression model results are shown in Table 1. Chest compression fraction was most strongly associated with ROSC and shockable rhythm. Depth was also associated with shockable rhythm. Leaning proportion and duty cycle were not associated with either outcome. Conclusions: In cases of non-shockable OHCA, CPR quality measures were associated with ROSC and transition to a shockable rhythm at the bout level.
