上臂止血带应绑在上臂的什么位置？
一般情况下，出血分三种，一是毛细血管出血，二是静脉出血，三是动脉出血，那么如果是上臂出血，上臂止血带应该绑在上臂的什么位置？
Generally, there are three kinds of bleeding: capillary hemorrhage, venous hemorrhage and arterial hemorrhage. If it is upper arm hemorrhage, where should the upper arm tourniquet be tied?
医生表示，患者上肢手术时止血带应绑在上臂的上1/3段，下肢手术时绑在大腿中上1/3段，上肢避开桡神经，下肢避免直接压迫股动脉。
Doctors said that the tourniquet should be tied to the upper 1/3 of the upper arm during upper limb surgery, the upper 1/3 of the upper thigh during lower limb surgery, the upper limb avoids the radial nerve, and the lower limb avoids direct compression of the femoral artery.
为什么要在1/3处？根据解剖学知识，这个位置肱动脉位置比较表浅，容易压迫止血。
Why in one third? According to the knowledge of anatomy, the position of brachial artery is superficial and easy to oppress hemostasis.
止血带设定压力：工作压力一般成人上肢≤40KPa，成人下肢≤80KPa。小儿上肢≤30KPa，下肢≤35KPa。
Setting pressure of tourniquet: Working pressure is generally less than 40KPa for upper limbs and 80KPa for lower limbs of adults. Children's upper limbs are less than 30KPa and lower limbs are less than 35KPa.
三种出血的情况：
Three types of bleeding:
1、毛细血管出血
1. Capillary hemorrhage
相当于小口子，问题不大，很快就能愈合，所以不需要怎么管，让伤口在空气中放置一段时间，自然会快速愈合。
Equivalent to a small mouth, the problem is not big, can heal quickly, so do not need how to manage, let the wound in the air for a period of time, will naturally heal quickly.
2、静脉出血
2. Venous hemorrhage
静脉出血的血液流出较多，但相对流出速度比较均匀，需要止血，但是相对而言，危险性还是动脉出血比较大。
There are more blood outflows from venous hemorrhage, but the relative outflow rate is relatively uniform, which requires hemostasis, but relatively speaking, the risk of arterial hemorrhage is greater.
3、动脉出血
3. Arterial hemorrhage
动脉出血时，心脏会用比较大的力量将血液压出，血液的流速较快，就像是水枪喷射而出，动脉出血时，不仅仅是血液的危机，还有心脏的危机，对心脏带去极大的压力，因此动脉出血时及时止血是非常重要的一件事。
When arterial hemorrhage occurs, the heart will use a greater force to squeeze blood out, and the blood flow is faster, just like a water gun spraying out. When arterial hemorrhage occurs, it is not only a blood crisis, but also a heart crisis, which brings great pressure to the heart. Therefore, timely hemostasis is very important when arterial hemorrhage occurs.
不同的部位对应着不同的止血点，选择合适的位置止血自然也很重要，比如说你上臂出血，总不能将止血带绑在流血口下方，这样不仅起不到止血作用，还会对身体造成极大的伤害。
Different parts correspond to different hemostasis points. It is also important to choose the appropriate songjiaoyou.07858.net diandongm.89ix.comfangdaomenw.89ix.com fengmao.89ix.comjialouyi.89ix.comtiaojiefad.89ix.comlocation for hemostasis. For example, if you have upper arm hemorrhage, you can't tie the tourniquet under the bleeding mouth. This will not only have no hemostasis effect, but also cause great harm to your body.
包扎的时候要注意松紧度，不能太松也不能太紧，只有力度适宜的松紧度才能真正起到止血作用。
When dressing, we should pay attention to the tightness, not too loose or too tight, only the appropriate tightness can really play a hemostatic role.
