Air embolism空气栓塞

An embolism can happen when something solid, semi-solid or gaseous is travelling in your bloodstream and gets stuck. 1栓塞时，会发生一些固体，半固体或气体，是一辆在您的血液和卡住。 The material that should not be there is called an embolus.材料认为，不应该有所谓的一栓。 The most common type of embolus is a clot of blood, but other things can cause an embolism too.最常见的栓子是一个血块，血液，但其他的东西，可能会造成栓塞。 Examples include crystals of cholesterol, clumps of infected cells, fat, bits of bone marrow, or a gas such as nitrogen or air.例子包括晶体中的胆固醇，进化感染的细胞，脂肪，位的骨髓，或气体，如氮气或空气。

An air embolism is when bubbles of air are in the circulating blood. 1空气栓塞是，当泡沫的空气是在循环的血液。 Air is made up of three main types of gases: oxygen, carbon dioxide, and nitrogen.空气是成立的三种主要类型的气体：氧，二氧化碳和氮。 In the bends, the air embolism is a bubble of nitrogen.在弯位，空气栓塞是一种泡沫的氮。 In other air embolisms, not caused by diving, the bubble contains a normal mix of air gases.在其他空气栓塞，而不是所造成的跳水，泡沫包含一个正常的空气混合气体。

An embolus in an artery is travelling in a system of tubes that are getting gradually smaller, so there is bound to be a point at which it blocks a small artery.一栓在一动脉是行驶在制度管得到逐步较小，所以难免会有一点，在它座的一小动脉。 This is always serious because it cuts off the blood supply to some area, but its effect will depend on the part of the body to which the artery supplies blood.这是历来严重，因为它切断血液供应的一些地区，但其效果将依赖于身体的一部分，这动脉供应血液。 It could, for instance, be part of your brain.它可以，例如，一部分你的大脑。 When blood supply is lost, tissues are starved of oxygen, causing them to die.当血液供应是失去了，组织是饿死的氧气，导致他们死亡。 If this happens in your brain, it can cause permanent brain damage.如果这种情况发生在你的大脑，它可以造成永久性脑损伤。

If the embolus is in a vein, the tube system widens along the direction of the blood flow, so a small embolus doesn't do much harm until it gets through the heart (after which it enters an artery).如果栓塞是在静脉，管制度，扩大沿方向血流量，使一个小栓子不伤害，直到它获得通过心脏（后进入动脉） 。
