Although chest compression-only cardiopulmonary resuscitation (CPR) is effective for adult out-of-hospital cardiac arrest (OHCA) of origin, it remains uncertain whether bystander-initiated rescue breathing has an incremental benefit OHCA noncardiac origin.A nationwide, prospective, population-based, observational study covering the whole population Japan and involving consecutive patients with emergency responder attempts was conducted from January 2005 through December 2007. The primary outcome neurologically intact 1-month survival. Multiple logistic regression analysis used to assess contribution CPR better neurological outcomes. Among a total 43 246 bystander-witnessed OHCAs 8878 (20.5%) received CPR, 7474 (17.3%) conventional breathing. group (1.8%) had higher rate than both no (1.4%; odds ratio, 1.58; 95% confidence interval, 1.28 1.96) (1.5%; 1.32; 1.03 1.69). However, did not produce (odds 1.19; 0.96 1.47). number needed treat versus save life favorable after 290.This nationwide indicates that but impact on overall survival small.
