A change in resuscitation protocol to a focus on CPR increased survival rates from 22% to 44% for cardiac arrest patients who suffered an attack outside of a hospital, according to new study results. The new recommendations call for CPR before defibrillation, increased chest compressions and less emphasis on ventilation and intubation. The Georgetown University researcher and lead author said the data add to a growing body of science that shows chest compressions are a key component to out-of-hospital cardiac intervention.
