A Hello everyone,and welcome to our CPR for beginners course.First of all, does anyone know what CPR stands for?

大家好，欢迎来到为初学者开设的CPR课程。首先，有谁知道CPR是什么意思？

B Cardiopulmonary resuscitation!

心肺复苏法。

A That’s right! We apply CPR in the case of cardiac arrest or pulmonary arrest.

对。我们在心脏停止跳动或肺停止跳动时使用心肺复苏法。

B What does that mean?

那是什么意思？

A Well, basically if your heart stops pumping blood, or your lungs stop pumping air, then we need to get them going again! That’s when we have to apply this procedure. Let’s begin! I need a volunteer.

如果你的心脏停止工学或是肺停止呼入空气，我们需要让心肺重新恢复功能。那时就是我们应用这一进程的时候，我们开始吧，我需要一个志愿者。

B Me! Me!

我！我！
