Resuscitation
-
Bystander cardiopulmonary resuscitation (CPR) is an important prognostic factor for outcome in out-of-hospital cardiac arrest (OHCA). The dispatcher-assisted (DA) bystander CPR program has increased the rate of bystander CPR by targeting bystanders with a lower level of CPR training. We evaluated the effects of dispatcher-assisted bystander CPR and self-led bystander CPR. ⋯ Although DA CPR was associated with better neurologic outcomes than no bystander CPR, good neurologic outcomes were most strongly associated with self-led bystander CPR.
