n.心脏复苏术；Cardiopulmonary Resuscitation的缩写
Traditional CPR should also be used for adults who are found already unconscious and not breathing normally. 传统心脏复苏术同样还适用于发现时已经昏迷并无法呼吸正常的成人。
Because there are many of these cases, people should still learn CPR with mouth-to-mouth. 正因为这么多的案例，所以人们依然需要学习口对口的心脏复苏术。
