刻意练习让耳朵更灵敏40

Material
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.
