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.
