Conventional cardiopulmonary resuscitation (CPR) Vs compression-only CPR

 
Bystanders who perform chest-compression-only CPR instead of traditional CPR with mouth-to-mouth resuscitation (rescue breathing) save more lives, Researchers found that adults who experienced cardiac arrest in a non-hospital setting, such as a restaurant or mall, were 60% more likely to survive if they received compression-only CPR than if they received traditional CPR or no CPR until an emergency medical services (EMS) crew arrived at the scene. The survival edge may occur because interrupting chest compressions --- even just for rescue breathing-- may further hamper blood flow, and it takes longer to get that blood flow back when it is time for more chest compressions.
