1
Use direct pressure to stop life-threatening bleeding when the wound is on the head, neck or trunk, the wound is on an arm or a leg and you are waiting for someone to bring you a tourniquet, or no tourniquet is available.
2
You can also use direct pressure to stop non-life-threatening bleeding.
3
It takes a lot of pressure to stop life-threatening bleeding.
4
That's why you need to push hard.
5
The amount of pressure might be painful for the injured person.
6
That's OK! You need to use a lot of pressure for the bleeding to stop.
7
A flat, hard surface underneath the injured body part allows you to press against something, increasing the effectiveness of the direct pressure.
8
To begin, if you have gloves, wear them.
9
But, if the bleeding is life-threatening and you don't have gloves, begin providing care immediately.
10
Make sure you wash your hands thoroughly after giving care.
11
Then, find the source of the life-threatening bleeding.
12
Remember, there may be more than one wound.
13
You need to focus on any wound that is causing life-threatening bleeding first.
14
Next, you are going to place a dressing on the wound.
15
A dressing is a pad that absorbs blood and can promote clotting.
16
Bleeding control kits and First Aid kits often contain special dressings called hemostatic dressings.
17
This is a hemostatic dressing.
18
It contains a substance that promotes clotting and can help stop bleeding faster.
19
When there is life-threatening bleeding, use a hemostatic dressing if you have one.
20
Otherwise, use a gauze pad or other available material, such as a clean T-shirt, as a dressing.
21
The technique of applying direct pressure is the same regardless of the type of dressing you use.
22
Place the dressing on the wound and push down with both hands.
23
You need to apply a lot of pressure to stop life-threatening bleeding, so let the person know it can be painful.
24
Sir, this could hurt.
25
Apply pressure directly over the wound until the bleeding stops.
26
Position your body over the wound so your shoulders are directly over your hands, with your elbows locked.
27
If you have been trained in CPR, you might recognize this position.
28
Push down, using your body weight to increase the pressure.
29
If you need your hands, use your knee to apply pressure.
30
If blood soaks through the original gauze pad, you don't need to do anything.
31
But you can apply an additional gauze pad and continue direct pressure.
32
If that gauze pad becomes soaked, you can remove that one and replace it with a new pad.
33
However, DO NOT remove the original gauze pad that is placed directly on the wound.
34
Also, only add one pad on top of the original.
35
Do not stack multiple pads as this weakens direct pressure.
36
If the bleeding stops before EMS arrives, check for circulation beyond the injury.
37
Note the temperature and color of the skin and ask the person if there is any tingling or numbness.
38
Sir, are you experiencing any tingling?
39
Any numbness?
40
Then apply a roller bandage over the dressing to hold it in place and maintain pressure on the wound.
41
Place the end of a bandage on the dressing at a 45 degree angle.
42
Continue wrapping the bandage over the dressing.
43
Then, tape to secure the dressing.
44
Check again for circulation beyond the injury.
45
If there is any change, the bandage may be too tight and you will need to carefully loosen the bandage.
46
Sir, are you experiencing any tingling?
47
Any numbness?
48
After the bandage is appropriately applied, remove your gloves and wash your hands.
49
So to summarize, when using direct pressure to stop bleeding, remember two key things: One... press as hard as you can, directly over the wound.
50
Two... hold the pressure until the bleeding stops.
51
Usually, this takes at least 5 minutes, but it could take much longer.
52
Keep applying direct pressure until: the bleeding stops, a tourniquet is applied for life-threatening bleeding from an arm or leg, another person relieves you, you are too exhausted to continue or the situation becomes unsafe.

这个视频适合谁？
无论你是备考雅思口语练习的考生，还是想通过英语影子跟读提升表达流畅度的学习者，这个视频都很合适。它的对话逻辑清晰、指令明确，语速适中，非常适合用来训练听力理解和模仿标准发音。视频中关于急救步骤的描述严谨且实用，能帮助学习者积累专业场景下的英语表达，同时提升在真实语境中使用语言的能力。
值得借鉴的词汇与表达
- life-threatening bleeding：危及生命的出血。在描述紧急情况时，"life-threatening"是高频词汇，可用于替换"dangerous"，增强表达的精准度。
- hemostatic dressing：止血敷料。"hemostatic"是医学术语，意为"止血的"，这类专业词汇能丰富学习者的词汇库，尤其适合雅思口语中涉及健康话题的讨论。
- direct pressure：直接按压。"direct"在这里强调"直接的"，与"pressure"搭配构成固定表达，是急救场景中的核心术语。
- EMS (Emergency Medical Services)：紧急医疗服务。这一缩写在英语对话中很常见，记住它能提升听力中的信息捕捉能力。
如何练好发音？
视频中说话者的发音清晰，重音和停顿处理得宜，非常适合shadowing site或shadow speak练习。练习时需注意以下几点：首先，关注"life-threatening" "hemostatic"等长单词的重音位置，如"hemostatic"的重音在第二个音节；其次，模仿说话者在给出指令时的语气，如"push hard" "DO NOT remove"等表达时的坚定感，通过重读关键词来传递信息的重要性；最后，注意句子的节奏，比如在描述步骤时，说话者会在每个步骤之间稍作停顿，这有助于学习者掌握英语表达中的逻辑停顿。通过反复跟读，不仅能提升发音的准确性，还能培养自然的语流，为雅思口语考试中的流畅表达打下基础。
视频中的语法
说话人最常用的结构，并附上视频中的原话：
| 结构 | 视频中的用法 |
|---|---|
| 被动语态 be + 过去分词 — 强调发生了什么，而不是谁做的 | have been trained · is placed · is applied |
| 用 “might / may” 表可能 might/may + 动词 — 有可能但不确定的事 | might be · may be · might recognize |
| 动词 + -ing enjoy、keep、stop… + -ing — 后接 -ing 形式的动词 | stop bleeding · Keep applying |
| 义务：must / have to / need to 表示某事是必要的 | need to push · need to use · need to focus |
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
