This is the VOA Special English Health Report.
Cardiopulmonary resuscitation, or CPR, can save the life of someone whose heart has stopped. The condition is called cardiac arrest. The heart stops pumping blood. The person stops breathing. Without lifesaving measures, the brain starts to die within four to six minutes.
CPR combines breathing into the victim's mouth and repeated presses on the chest. CPR keeps blood and oxygen flowing to the heart and brain.
However, a new Japanese study questions the usefulness of mouth-to-mouth breathing.
The study was published in the British medical magazine, The Lancet. Doctors in Tokyo led the research. It examined more than four thousand people who had suffered cardiac arrest. In all the cases, witnesses saw the event happen.
More than one thousand of the victims received some kind of medical assistance from witnesses. Seven hundred and twelve received CPR. Four hundred and thirty-nine received chest presses only. No mouth-to-mouth rescue breaths were given to them.
The researchers say any kind of CPR improved chances of the patient's survival. But, they said those people treated with only chest presses suffered less brain damage.?
Twenty-two percent survived with good brain ability. Only ten percent of the victims? treated with traditional CPR survived with good brain ability.
The American Heart Association changed its guidelines for CPR chest presses in two thousand five. It said people should increase the number of chest presses from fifteen to thirty for every two breaths given.
Gordon Ewy is a heart doctor at the University of Arizona College of Medicine in Tucson. He wrote a report that appeared with the study. Doctor Ewy thinks the CPR guidelines should be changed again. He said the heart association should remove rescue breaths from the guidelines.
He argues that more witnesses to cardiac arrests would provide treatment if rescue breaths are not a part of CPR. He says this would save lives. Studies show that many people do not want to perform mouth-to-mouth breathing on a stranger for fear of getting a disease.
Cardiac arrest kills more than three hundred thousand people in the United States every year. The American Heart Association says about ninety-five percent of victims die before they get to a medical center.

今日是自習(xí)廉丽，估計(jì)是為了照顧考研的同學(xué)圆丹。依照要求扛点，我把問(wèn)卷填了告组，背誦了前5段掠归，把每個(gè)字的音標(biāo)從給到的網(wǎng)站上搜了出來(lái)。仔細(xì)對(duì)著音標(biāo)讀了幾遍受楼，覺(jué)得它們認(rèn)識(shí)我我雖然算是基本上還認(rèn)識(shí)它們吧转唉，不過(guò)發(fā)音時(shí)嘴型和舌頭的位置等估計(jì)大都都是不對(duì)的。因?yàn)槌踔写蚧A(chǔ)時(shí)應(yīng)付差事贩绕，管它應(yīng)該往哪兒放火的，覺(jué)得差不多就行了，然后結(jié)果就是淑倾，開(kāi)不了口…
記得前期學(xué)員講到S會(huì)每個(gè)音逐一地講一遍馏鹤，會(huì)非常仔細(xì)，這也是我進(jìn)群的主要原因之一娇哆，非常期待假瞬。
