Knowing a little first-aid could be life-saving if you see someone lying unconscious.

如果你看見有人暈倒，而你又了解一些急救措施，那很可能會(huì)挽救一條生命。

Too often people don't do anything because they think they will kill the patient, but by learning simple rules you could make the difference between life and death.

通常人們都是什么都不做，因?yàn)樗麄冋J(rèn)為自己的做法可能會(huì)害死病人。但是學(xué)習(xí)些簡(jiǎn)單的措施你就可能救死扶傷了。

First, you need to find out if they're unconscious, asleep or drunk, by squeezing the skin between their neck and shoulder and shouting.

首先，你需要通過擠壓他們脖子和肩膀之間的皮膚，并大聲呼喊來(lái)確定他們是無(wú)意識(shí)了，還是睡著了或者喝醉了。

If there is no response at all, you need to establish if they are dead or just unconscious - sometimes it's very difficult to tell the difference.

如果沒有回應(yīng)的話，你需要確定他們是死了還是僅僅是暈過去了，雖然有時(shí)是很難分辨清楚。

Open the airway by placing one hand on their forehead and gently tilting the head back while lifting the chin.

把一只手放在他們的前額慢慢的把頭向后傾，同時(shí)抬高下顎以確保呼吸順暢。

If there are no signs of life - no obvious pulse and their chest is not going up and down - call an ambulance and then start cardiopulmonary resuscitation (CPR) to maintain a flow of oxygenated blood to the brain and heart.

如果沒有明顯的脈搏和心臟跳動(dòng)，那就是沒有生命跡象了。此時(shí)要立刻叫救護(hù)車并開始心臟救援以保持充了氧氣的血液在大腦和心臟之間流通。

Do this by pushing up and down on the centre of the chest, with your hands interlocked together, constantly until an ambulance arrives.

把你的手交叉相扣，按住胸腔中心部分上上下下的不停的按，直到救護(hù)車到達(dá)。

Push at a rate of 100 beats a minute。You can't harm them doing this and might just save a life.

保持一分鐘一百次的頻率。你這樣做不會(huì)傷害到他們，但卻能挽救一條生命。
