NEW ORLEANS — Children benefit more from conventional CPR that includes rescue breath, but black and Hispanic children are more likely to receive the compressions-only method, according to research presented at the American Heart Association’s Scientific Sessions 2016.

Using a large national registry in the United States, Philadelphia researchers examined the outcomes of out-of-hospital cardiac arrests in children 18 years and younger. Of 1,458 arrests treated with bystander CPR between 2013-2015, 49 percent of children received conventional CPR, 50 percent were given compressions-only CPR, and 1 percent had ventilation-only CPR.

Among the findings:

— Compressions-only CPR was used more often in black children (56 percent) and Hispanic children (64 percent) than in white children (49 percent).

— Although black children were more likely to receive compressions-only CPR, their survival was better if they received conventional CPR.

— Conventional CPR was associated with a 60 percent better chance of survival and a 50 percent better chance of being discharged from the hospital with good brain function.

— Infants were more likely to receive conventional CPR. That approach improved their survival more than compressions-only CPR.

— Overall, survival was 17 percent for conventional CPR and 14 percent for compressions-only CPR.

The American Heart Association recommends conventional CPR, including compressions and rescue breaths for infants and children. If rescuers are unwilling or unable to deliver breaths, they should perform compressions-only CPR.
