Scientists believe that the heart of artificial respiration hinder aid.

<P> Most people on television or seen in real life scenes of emergency heart attack patients: a pedestrian suddenly his hands on his chest, face down on the sidewalk in pain. .At this time, the patient was rushed to the side and started doing mouth to mouth resuscitation and chest compressions, the implementation of first aid. .</ P> <P> However, this is the first aid procedure used to but now questioned by some scientists. .They believe that patients with heart disease first aid in the process of artificial respiration is not only no good, but will harm the patient. .</ P> <P> question the traditional </ P> <P> 16 issue of The British medical magazine "Lancet" published results show that the process only if the first-aid for patients with heart disease, chest compressions, and give up .artificial respiration, first aid will double the success rate. .</ P> <P> the study leader, Dr Yong-Mei Japanese university hospital building (transliteration), wrote in a research report, they study the Kanto region by 4000 heart attack patients found that "there is no evidence that ., first aid of artificial respiration on the heart benefit. " .</ P> <P> University of Arizona Heart Center for treatment of Gordon Uys said: "The conventional cardiopulmonary resuscitation (CPR) first aid and choking first aid to the heart of the method mix, in fact, artificial respiration only choking first aid. Hope .The results can correct this error has lasted 40 years the concept. "</ P> <P> worth the </ P> <P> to chest cardiac compression may play a role in normal heart, artificial respiration of patients will increase .blood oxygen content. .However, results show that oxygen to the heart of people no good. ."We found that maintaining low blood oxygen content, and rhythmic chest massage, first aid success rate will be higher," Uys wrote in a research report, "More importantly, mouth resuscitation to waste valuable .The emergency time. "</ P> <P> researchers also said their investigation of the Japanese 4068 heart attack was in the public of those, 70% did not receive first aid pedestrians. .The reason is that most people do not want strangers on the implementation of mouth resuscitation. .So, if the process of abolition in the heart of emergency artificial respiration steps, there will be more people willing to participate in emergency work. .</ P>.
