For years, scientists have questioned whether the mouth-to-mouth part was necessary, saying the focus of CPR should be on chest compression, which keeps blood flowing to vital organs after cardiac arrest. Last month, a study of more than 4,000 cases of cardiac arrest, the largest on the subject to date, found that patients were more likely to recover without brain damage if their rescuers had focused on chest compressions alone. Published in The Lancet, the study found that 22 percent of people who received chest compressions alone survived with good neurological function, compared with 10 percent who received combination CPR. Those findings echoed those of a study in The New England Journal of Medicine in 2000. The reason is that in most cases of cardiac ar
