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 m 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.
