CPR in Action

心肺复苏术（CPR）操作方法

Our heart is an amazing organ. It works hard for us every second of every day,  delivering blood and oxygen to every cell in our body.

我们的心脏是一种奇妙的器官。它每时每刻都在“努力工作”，为我们身体的每一个细胞输送血液和氧气。

But when Sudden Cardiac Arrest strikes,  our heart suddenly and unexpectedly stops  beating effectively and blood flow stops. Without any intervention, the brain, vital  organs, and our heart will begin to die.

但是，当心脏骤停发作时，我们的心脏将突然停止有效跳动，导致血流停止。如果不采取任何干预措施，大脑、重要器官和我们的心脏将开始死亡。

Beginning CPR is the person's only chance of survival. Brain damage will start to set in within four minutes,  and after 10 minutes, brain damage becomes irreversible. The Power to Save a Life is truly in your hands.

启动 CPR 是病人唯一的生存机会。大脑将在 4 分钟内，开始损伤，10 分钟后，脑损伤将不可逆转。你需要挽救生命！

Performing CPR accomplishes two critical things: 

CPR 可实现关键的两点：

1. compressions move oxygenated blood to the brain, to keep the brain alive. 

1. 按压将含氧血液输送到大脑，保持大脑安然无恙。

2. compressions keep blood and oxygen moving to the heart muscle itself so that it has the best chance of resuming a normal  electrical rhythm after a shock is delivered.

2. 按压保持血液和氧气流向心肌，这样，电击后，心脏能够恢复正常的电节律。

As you begin compressions,  you are creating an artificial pump and  doing the work of the heart manually. With each good effective compression you  are building up pressure in the system  which will move blood around  the heart and up to the brain.

随着按压，我们将创建一个人工泵，人为辅助完成心脏的工作。每一次有效按压都会对系统施加压力，使血液在心脏周围流动，并向上到达大脑。

It does take time to get the blood moving  with CPR so it is very important to PUSH HARD and PUSH FAST to build the pressure  up, which keeps blood going to the brain.

通过 CRP 使血液流动需要一定的时间，因此，关键是用力按压和快速按压，从而增加血压，保持血液流向大脑。

Pushing down at least two inches allows for  the heart to be squeezed and blood to move out. Pushing at a rate of 100 to 120 compressions  per minute is necessary to keep blood pumping.

向下按压至少 2 英寸，挤压心脏，使血液流出。以 100-120 次/分钟的速度按压是保持血液泵送的必要条件。

Let's see what happens when we take our hands off the chest. 

我们看一下，如果将手从胸前移开会发生什么。

Blood stops moving to the brain. It is for this reason that if you are taking your hands off the  chest to deliver breaths, or switching rolls,  it is critical to minimize time off the chest.

血液将停止流向大脑。因此，如果将手从胸前移开，进行人工呼吸，或人工呼吸，然后按压，那么，尽量缩短手离开胸部的时间至关重要。

Watch what happens when we don't push deep  enough. 

注意观察，按压不够深时会发生什么。

Blood does not reach the brain. The same is true if we do not push fast enough.  

血液不会到达大脑。按压不够快，血液也不会到达大脑。

Watch what happens when we push too fast.  

观察一下，按压过快会怎样。

The heart does not have time to refill with  blood, therefore not enough blood gets pumped out.

心脏没有时间充满血液，因此泵出的血液不足。

Watch what happens when we don't allow the body to decompress and allow the chest to fully recoil.  

观察一下，按压不足，胸腔未完全回弹时会怎样。

The heart does not have a chance to refill with blood, therefore no blood gets pumped out.

心脏不能充满血液，因此没有血液泵出。

So remember, the key purpose of  delivering compressions is to keep  oxygenated blood moving within the heart and up to the brain  to keep the brain alive. We need to PUSH HARD and PUSH FAST in the center of the chest. If ribs break, that's okay. What's not okay is  allowing the brain to die from a lack of oxygen. 

注意，按压的关键目标是保持含氧血液在心脏内流动，并向上到达大脑，保持大脑无恙。我们需要用力按压和快速按压胸腔中央。即使肋骨骨折也没关系。但是不能使大脑因缺氧死亡。

So remember, you are their only hope.  Do the best you can and don't give up until  medical help arrives or an AED is present. You can do it! 

请记住，你是病人的唯一希望。救护人员到达前，或 AED 送达前，请尽全力，不要放弃！你能做到！
