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.

Scalers英語晨讀第7期明天就結束了，今天我才發(fā)現(xiàn)我這二十幾天的標題全都是錯的，這也太讓人尷尬了，失敗湖笨。才睹。。不過還是有很大很大的收獲的筹误。首先蟹但，這二十幾天我?guī)缀趺刻於加姓J真的朗讀英語，死扣音標拂苹，這是我以前根本完成不了的事安聘，雖然量不多，但是至少去做了瓢棒，堅持了下來浴韭。然后就是非常的感謝S老師每天早上6點的準時授課了，真的是好厲害脯宿，每天都好準時念颈。即使前一天晚上熬夜，第二天也會準時的給我們上課连霉，而我有的時候還躺在床上聽課榴芳，也有直接關掉直播課的情況。太對不起老師的辛苦了跺撼。窟感。。最后一天的作業(yè)财边，朗讀全篇文章肌括，讀下來后才知道自己還是掌握的不夠好，還有很多很多忘記的地方酣难，根本順不下來谍夭，讀著讀著經(jīng)常會停下來想想這個音標應該怎么發(fā)音，還是沒有熟練的掌握憨募。所以晨讀課雖然結束了紧索，但是我的英語晨讀還遠遠沒有結束，雖然S老師說大部分人還會堅持個那么十幾天菜谣，之后就沒有什么結果了珠漂。我還是老老實實的把這十幾天熬過去，再說其他的那些豪言壯語吧~我是真的想把這篇文章練的像S老師那樣的熟練的尾膊，看看我能走到哪一步吧~最后的最后媳危，再次感謝S老師的辛勤教導，謝謝冈敛！成長會待笑，讀書會繼續(xù)跟著S老師一起持續(xù)行動！
