It remains unclear which is more effective to increase survival after out-of-hospital cardiac arrest in those with public-access defibrillation, bystander-initiated chest compression-only cardiopulmonary resuscitation (CPR) or conventional CPR rescue breathing.A nationwide, prospective, population-based observational study covering the whole population of Japan and involving consecutive patients attempts has been conducted since 2005. We enrolled all arrests presumed origin that were witnessed received shocks automated external defibrillation (AEDs) by bystanders from January 1, 2005, December 31, 2009. The main outcome measure was neurologically favorable 1-month survival. compared outcomes type (chest compressions breathing). Multivariable logistic regression used assess relationship between a better neurological outcome. During 5 years, 1376 bystander-witnessed individuals who AEDs registered. Among them, 506 (36.8%) 870 (63.2%) CPR. group (40.7%, 206 506) had significantly higher rate than (32.9%, 286 870; adjusted odds ratio, 1.33; 95% confidence interval, 1.03-1.70).Compression-only for whom shocked defibrillation. Compression-only most likely scenario lay rescuers can witness sudden collapse use AEDs.
