AED stands for "Automatic External Defibrillator." An AED is used to administer an electric shock to a person who is having a cardiac arrest. AEDs are designed to allow non-medical personnel to save lives.

什么是 AED?  - AED 是“自动体外除颤器”的缩写，它可用来为心脏骤停的人提供电击。使用 AED，非医务人员也能拯救生命。

Two pads, connected to the AED, are placed on the patient's chest. A computer inside the AED analyzes the patient's heart rhythm and determines if a shock is required to save the victim. If a shock is required, the AED uses voice instructions to guide the user through saving the person's life.

AED 是如何工作的？

答：将连接在 AED 上的两个电击垫粘贴在患者胸部。AED 将自动检测并分析患者的心律，然后判断是否需要电击。若需要电击，AED 将发出语音提示，指导操作者如何挽救该患者的性命。

AEDs save lives. When a person has a sudden cardiac arrest ("SCA"), their heart's regular rhythm becomes chaotic or arrhythmic. Every minute that the heart is not beating lowers the odds of survival by 7% to 10%. After 10 minutes without defibrillation very few people survive.

为什么需要 AED?

答：AED 可以拯救生命。心脏骤停时，患者的心律变得紊乱而没有节奏。心脏跳动停止一分钟，患者的存活率将减少 7% 至 10%。若 10 分钟未进行除颤，患者的存活率几乎为零。

Sudden cardiac arrest is when the heart's normal heart rhythm suddenly becomes chaotic. The heart can no longer pump the blood effectively and the victim collapses, stops breathing, becomes unresponsive, and has no detectable pulse. When used on a victim of SCA, the AED can be used to administer a life-saving electric shock that restores the heart's rhythm to normal.

什么是心脏骤停（SCA）?

心脏骤停就是心脏通常有节奏的心律突然变得紊乱。此时，心脏不能有效地供血，患者停止呼吸、失去知觉、不省人事，其脉搏无法检测。心脏骤停时使用 AED，即可为患者提供电击，使其心律恢复正常。

No. Both the heart attack (myocardial infarction) and a sudden cardiac arrest have to do with the heart, but they are different problems. SCA is an electrical problem; a heart attack is a "plumbing" problem. Sometimes a heart attack, which may not be fatal in itself, can trigger a sudden cardiac arrest.

心脏骤停（SCA） 和心脏病突发是一回事吗？

答：不是。心脏病突发（心肌梗死）和心脏骤停两者都和心脏有关，但它们是不同的问题。SCA 是心电问题，而心脏病突发是心血管的问题。有时候，心脏病突发本身并不是很危险，但却有可能导致心脏骤停。

Anyone, anytime. Children can have SCAs, teenagers can have SCAs, athletes can have SCAs, old people can have SCAs. Although the risk of SCA increases with age and in people with heart problems, a large percentage of the victims are people with no known risk factors.

什么人会患 SCA?

答：任何人任何时间都有可能发生，无论是小孩还是大人，无论是运动员还是普通群众。虽然 SCA 发病率随年龄的增长而增加，在心脏有问题的人群中也相应更高，但还有一大部分患者的病因却无法查明。

The AHA strongly supports having AEDs in public areas such as sports arenas, office complexes, schools, doctors' offices, shopping malls, airports, and other public places. The AHA also advocates that all police and fire and rescue vehicles be equipped with an AED.

美国心脏协会如何评价 AED？美国心脏协会强烈支持在公共场合（例如：运动场、办公楼、学校、医院办公楼、商场和机场等）安装 AED。他们还建议所有公安和消防救护车上都配备 AED。

Defibrillation is the only treatment proven to restore a normal heart rhythm.

心脏骤停时推荐采取什么应急措施？实践证明，除颤是使心律恢复正常的唯一措施。

Only minutes. Defibrillate within 3 minutes and the chances of survival are 70%. After 10 minutes, the chances of survival are negligible.

心脏骤停时，进行抢救前的延缓时间可以有多长？只有几分钟。3 分钟内进行除颤，患者的存活概率为 70%；10 分钟后存活的概率几乎为零。

CPR only buys a little more time – potentially giving the victim a small amount of extra time until a defibrillator arrives. But SCA ultimately requires a shock to restore a normal heart rhythm. As a result, most CPR training now also includes AED training.

具有 CPR 知识对 SCA 是否有帮助？CPR 只能为您赢得一点点时间——使患者等待除颤器到来的时间稍微延长，患者最终还是需要电击才能恢复正常心律。因此，现在大多数 CPR 培训都包括 AED 培训。

AEDs are very easy to use. An AED can be used by practically anyone who has been shown what to do. In fact, there are a number of cases where people with no training at all have saved lives.
AED 使用起来复杂吗？AED 使用非常简单。任何看过他人演示如何操作的人都会使用 AED。事实上，很多没受过培训的人使用 AED 成功挽救了患者的性命。

AEDs are safe to use by anyone who has been shown how to use them. The AED's voice guides the rescuer through the steps involved in saving someone; for example, "apply pads to patient's bare chest" (the pads themselves have pictures of where they should be placed) and "press red shock button." Furthermore, safeguards have been designed into the unit precisely so that non-medical responders can't use the AED to shock someone who doesn't need a shock.
非医务人员使用 AED 会产生失误吗？任何看过他人演示如何操作的人都能安全操作 AED。AED 在整个拯救过程中会发出语音提示指导操作者，例如，“按照图示贴电击垫在病者赤裸胸上”（电击垫包装图示指明了粘帖位置）和“按闪亮电击按钮”。此外，该机器中还设有保护措施，以防非医务人员在患者无需电击时误施电击。

It is unlikely. Studies show that AEDs interpret the victim's heart rhythm more quickly and accurately than many trained emergency professionals. If the AED determines that no shock is needed, it will not allow a shock to be given.
AED 本身会产生失误吗？不会。研究表明 AED 对患者心率的诊断比许多经过培训的急救专业人员更迅速、更准确。若 AED 诊断无需电击，它将禁止发出电击。

State and federal "Good Samaritan" laws cover users who, in good faith, attempt to save a person from death. To date, there are no known judgments against anyone who used an AED to save someone's life.
拯救心脏骤停的人会不会给自己带来民事纠纷？州政府和联邦政府的好撒马利亚人法（Good Samaritan law）就是给伤者、病人的自愿救助者免除责任的法律，目的在于让做好事的人没有后顾之忧。迄今为止，还没有人因为使用 AED 帮助别人而受到控告。

Even though the Defibtech AED has only been on the market since 2003, it has already saved a number of people's lives.
是否有人因使用 Defibtech AED 而被救活？虽然 Defibtech AED 在 2003 年才上市，但它已成功挽救了若干人的性命。

The Defibtech AED comes with a lithium battery pack that is available in a 5 or 7-year size. If the unit is used frequently, the battery pack may have to be replaced more often. The AED will inform the user when the battery pack needs to be replaced.
电池多久需要更换一次？Defibtech AED 的锂电池包有两种，其寿命分别为 5 年和 7 年。若机器频繁使用，电池包可能在更短时间内需要更换。电池需要更换时，AED 会通知用户。

The pad package must be replaced every two years. Otherwise, the AED performs automatic self-checks on a regular basis to test its operational readiness. If anything is not fully functional, the unit will make a loud chirp and flash a red light warning the owner that servicing may be required.
为保持 AED 正常工作还需做什么？ 电击垫 2 年需更换一次。AED 会定期进行自检。若任何部件出现问题，AED 会发出响亮的报警声并闪烁红灯，提醒用户机器可能需要维修。

Look for 1) an AED that is easy for non-medical people to use, 2) an AED that is technically reliable, and 3) one that is reasonably priced. Defibtech's AED more than meets all three requirements.
购买 AED 应考虑哪些要素？ 1）非医务人员也能简易操作，2）技术可靠，3）价格合理。Defibtech 生产的 AED 完全具备以上三个要素。

Defibtech designed the unit from the ground up, building on a foundation of previous AED-related knowledge and incorporating a number of design and technological innovations. As a result, the Defibtech AED is a state-of-the-art defibrillator designed for the non-medical person. Advanced design techniques and robotic assembly allow Defibtech to sell their AED at the lowest price in the market.
Defibtech AED 为什么比其它 AED 更好？Defibtech 生产的 AED 以先前 AED 相关知识为基础，自始至终都由自己设计，并纳入了一些设计和技术革新。因此，Defibtech AED 是美国为非医务人员使用而设计的最先进的除颤器。而先进的设计技术和机器人装配又使 Defibtech AED 成为市场上价格最实惠的除颤器。

The Defibtech AED is warranteed for five years.
Defibtech AED 保修期是多久？ 5 年。
