2015年职称英语卫生类教材学习部分内容及解析 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 arrest.2 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 victims mouth and repeated presses on the chest. ____________________ However, a new Japanese study questions the usefulness of mouth-to-mouth breathing. The study was published in the British medical magazine, The Lancet.3 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. __________________ The researchers say any kind of CPR improved chances of the patients survival. But, they said those people treated with only chest presses suffered less brain damage. Twenty-two percent survived with good brain ability. ____________________ The American Heart Association4 changed its guidelines for CPR chest presses in 2005. ____________________ 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. ____________________ |
