Early Double Sequential Defibrillation in Out of Hospital Cardiac Arrest

Some of the patients affected by Out-of-hospital cardiac arrest (OHCA) with ventricular fibrillation (VF)/ventricular tachycardia (VT) do not respond to initial defibrillation. The survival decreases with number of defibrillations required to terminate VF/VT. In 2022, one prospective cluster randomized trial showed increased survival among (OHCA) patients in refractory VF using Double Sequential Defibrillation (DSD). If DSD can increase survival among all patients in VF that dont respond to one defibrillation, i.e. before it has become refractory is not known. The aim of this trial is to assess survival with a double defibrillation strategy initiated as soon as possible among patients with Out of Hospital Cardiac Arrest with initial shockable rhythm and at least one failed standard defibrillation, compared with continued resuscitation using standard defibrillation.

the Effectiveness of Continuous Compression-synchronous Ventilation (Bio-CPR)

Bio-CPR is an innovative new mechanical resuscitation model proposed by our research group. A multi-center RCT study was established to comprehensively evaluate the efficacy of this model and the current standard CPR protocol, verify its safety and efficacy, and provide high-quality clinical evidence support.

PEEP vs. ZEEP in Out-of-Hospital-Cardiac-Arrest

Out-of-hospital cardiac arrest (OHCA) remains a major cause of mortality, with low survival probabilities to hospital discharge. Despite the frequent use of airway management and mechanical ventilation during resuscitation, there is limited evidence regarding the optimal ventilation strategy to improve oxygen delivery and patient outcomes. The present study aims to investigate the effects of positive-end-expiratory-pressure (PEEP) set at 5 mbar compared to zero-end-expiratory-pressure (ZEEP) on the return of spontaneous-circulation (ROSC) in adult patients with OHCA.

Effect of an Educational Intervention on CPR Knowledge and Skills in Schoolchildren

This study aims to evaluate the effectiveness of a CPR intervention for children aged 7 and 8. Given the high prevalence of out-of-hospital cardiac arrests (OHCA) and the proven benefits of early CPR training, the study seeks to determine whether a structured intervention can improve young children's knowledge and skills in basic life support. What is the effect of a CPR training intervention on the knowledge and skills of 7- and 8-year-old schoolchildren? Cardiac arrest is a leading cause of mortality worldwide. Research shows that survival rates increase significantly when CPR is performed promptly by a trained bystander. Countries with early CPR training programs in schools, such as Norway and Denmark, report better survival outcomes. However, in Latin America, CPR education in schools is still in its early stages. Evidence suggests that children can effectively learn and retain CPR knowledge, and they can serve as multipliers by passing their knowledge to family and peers. Study Design: This is a non-randomized, double-blind controlled trial with four phases:
