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.

很多单词看上去认识会读，但是深究起来又不知道准确的含义

感受与评价（Comments）：

文章粗看其实不难，但是深究起来就会发现有很多专用名词我是不知道它的确切翻译的。通读全文的时候，我特别注意到今天早上学的四个发音：[θ],[ð],[v],[f],我发现我平时读的时候错误的地方还是挺多的，例如[θ]，我知道它的正确读法，但是在平时说话的时候稍不留神就会读成[s]，这就导致我发音不够准确。这是我以后说话的时候应该注意到的地方：每一个发音都要读准确，不能求快而忽视错误。
