Chest Compressions:Most Important of CPR

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._________(46)
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._______(47)
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._________(48)
The American Heart Association changed its guidelines for CPR chest presses in 2005._________(49)
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,
_______(50)
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.

_________（50）
A:So far,we have not known exactly yet whether mouth-to一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 fearof getting a disease.
E:It said neonle 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.

Scientists Develop Ways of Detecting Heart Attack

German researchers have come up with a new generation of defibrillators（除颤器）and early-warning
software aimed at offering heart patients greater________ (51)from sudden death from cardiac arrest（心脏
停搏）.
In Germany alone,around 100,000 people die annually________(52)a result of cardiac arrest and
many of these cases are caused by disruption to the heart's rhythm.Those most at________(53)are pa-
tients who have already suffered a heart attack,and for years the use of defibrillators has proved useful in
________(54)life-threatening disruptions to heart rhythms and correcting them automatically by intervening
within seconds.These devices________(55)on a range of functions,such as that of pacemaker（起
搏器）.
Heart specialists at Freiburg's University Clinic have now achieved a breakthrough with an implanted
defibrillator________(56 ) of generating a six-channel electrocardiogram ( EGG，心电图）within the body.
This integrated system allows _________( 57 ) diagnosis of severe blood-flow problems and a pending（即将发
生的）heart attack. It will be implanted in _________( 58 ) for the first time this year. Meanwhile , research-
ers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer soft-
ware that________(59)the evaluation of EGG data more precise.
The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this
________(60)undergo regular EGGs."Many of the current programs only take into________(61)a line-
ar correlation of the data. We are,however,making use in a non-linear process________(62)reveals the
chaotic patterns of heart beats as an open and complex system,"Hagen Knaf says,"In this way changes in
the heart________(63)over time can be monitored and individual variations in patients taken into ac-
count."An old study of EGG data,based upon 600 patients who had________(64)a subsequent heart
attack,enabled the researchers to compare risks and to show that the new software evaluates the________
(65)considerably better.

_________(60)
A:reason
B:purpose
C:treatment
D:chance
