Borron said further research on the subject is necessary -- preferably studies that focus on family-witnessed CPR in the United States, both at home and in the hospital.
"I think we have to be cautious in extrapolating the results of this study from France to the U.S., in that their [emergency medical system] is very different from ours," Borron said. "But I think many physicians may be willing to examine their thought process on this."
The U.S. National Library of Medicine offers more on CPR.
