Chest Compressions: Most Important of CPR1

　　Cardiopulmonary resuscitation, or CPR, can save the life of someone whose heart has stopped. The condition is called cardiac arresta. 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.____1___.

　　However, a new Japanese study questions the usefulness of mouth-to-mouth breathing. The study was published in the British medical magazine, The I, ancet3. 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___2___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 ___3____.

　　The American Heart Association4 changed its guidelines for CPR chest presses in 2005.

　　___4___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___5___.

　　Cardiac arrest kills more than 300,000 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.

　　A So far, we have not known exactly yet whether mouth-to-mouth breathing is really useless in CPR.

　　B Only ten percent of the victims treated with traditional CPR survived with good brain ability.

　　C CPR keeps blood and oxygen flowing to the heart and brain.

　　D His studies show that many people do not want to perform mouth-to-mouth breathing on a stranger for fear of getting a disease.

　　E It said people should increase the number of chest presses from fifteen to thirty for every two breaths given.

　　F No mouth-to-mouth rescue breaths were given to them.

　　參考答案：C F B E D

　　答案解析：

　　1. C 本空白處的前一句是介紹CPR是什么，而六個(gè)選項(xiàng)中，C項(xiàng)也是介紹CPR的，因此放在一起是恰當(dāng)?shù)摹?/P>

　　2. F 本空白處的前一句說(shuō)“439位病人僅僅接受了胸腔按壓”，而第一段說(shuō)過(guò)，“CPR包括胸部按壓和白對(duì)口呼吸”，可見(jiàn)F項(xiàng)說(shuō)“沒(méi)做口對(duì)口呼吸的急救措施”是補(bǔ)充說(shuō)明前一句的。

　　3. B 本空白處的前面兩句說(shuō)到，只用胸部按壓搶救過(guò)來(lái)的人大腦受損比較小，存活下來(lái)的人中有22%大腦功能良好，接下來(lái)這一句肯定是要與傳統(tǒng)的兩種方法結(jié)合的搶救模式作對(duì)比，選項(xiàng)B正好是這樣的內(nèi)容。

　　4. E 本空白處的前一句是說(shuō)美國(guó)心臟協(xié)會(huì)于2005年修改了CPR中胸部按壓的指導(dǎo)準(zhǔn)則，空白處的后面又沒(méi)有提到如何修改，選項(xiàng)E正好填補(bǔ)了這個(gè)內(nèi)容。而且還要注意，選項(xiàng)E中的It said只能適用于American Heart Association，其他空白處均不合適。

　　5. D 這一段都是敘述心臟疾病醫(yī)生Gordon Ewy的觀點(diǎn)，在其他地方都沒(méi)有提到他，因此選項(xiàng)D His studies show…實(shí)際上已經(jīng)為我們提供了答題的線索，內(nèi)容也能前后銜接。
