HbH molecules cause hypoxia in two ways.

HbH分子引起缺制有两种。

You would gradually begin experiencing worsening cases of cerebral hypoxia.

你大脑缺情况会逐渐恶化。

This hypoxia also causes the parasympathetic nerve fibers to die off.

这种缺还会导致副交感神经纤维死亡。

So, the tissues get no oxygen, resulting in severe hypoxia.

因此组织无法获得气，导致重度缺。

This condition is called hypoxia and it is deadly to fish and shrimp.

这就造成缺，对鱼类和虾类来说是致命。

This slightly improves the blood flow and ameliorates hypoxia.

这样可以稍微改善血流，缓解缺状态。

Our cabin altitude at one time had reached 16000 feet. Some passengers have symptoms of hypoxia.

454. 我们座舱高度曾达到16000英尺。部分旅客有缺症状。

Inflamed airways along with atelectasis and air trapping due to mucus plugs can lead to difficulty breathing and hypoxia.

气管产生炎症，以及黏液栓导致肺不张以及气体潴留，会导致呼吸困难和缺症。

Well in response to low oxygen levels, or hypoxia, the pulmonary arterioles constrict, which raises the pulmonary blood pressure.

为应对低水平或缺，肺小动脉会收缩，这就容易引起肺高血压。

It then takes oxygen from the water. This condition is called hypoxia and it is deadly to fish and shrimp.

这样就从水中吸去气，这个过程叫做缺，这对鱼类和虾来说是致命。

Severe hypoxia leads to high-output cardiac failure and massive hepatosplenomegaly, resulting in edema all over the body, called hydrops fetalis.

重度缺会引起高输出量性竭和巨大肝、脾，进而出现全身性水肿，称为水肿胎儿。

He's in respiratory failure due to acute hypoxia.

他因急性缺导致呼吸竭。

In these cases, hypoxia can become a powerful stimulant for ventilation.

在这些情况下，缺可以成为一种强有促进通气物质。

However, increased metabolism due to illness can decrease oxygen levels - that is, cause hypoxia.

然而，疾病引起新陈代谢增加会降低气水平，也就是说，导致缺。

Hypoxia, or lack of oxygen, can affect anyone at extreme heights. That is why passenger planes are equipped with oxygen masks.

任何人在非常高地方都会出现缺，因此客都配备气面罩。

This cuts off the oxygen supply and hypoxia develops, which causes cells to start releasing substances like histamine and nitric oxide.

这从而阻断气供应导致缺，缺引起细胞开始释放组胺与一化氮。

If hypoxia lasts too long, intracellular edema can lead to cell membrane rupture, causing proteins to leak out into the extracellular space.

如果缺时间过长，细胞内水肿会造成细胞膜破裂，导致蛋白质外漏到细胞外。

Complications on the maternal end are related to the amount of blood loss, and fetal complications can include hypoxia and preterm delivery.

对于母亲来说，相关并发症取决于出血量多少，对胎儿影响包括缺和早产。

In capillaries, the basement membrane can thicken and make it difficult for oxygen to easily move from the capillary to the tissues, causing hypoxia.

在毛细血管中，基底膜会变厚，使气不能轻易地从毛细血管穿到组织中，从而造成缺。

As a result of ischemia, in the myocardium supplied by coronary artery B, the myocardial cells don’t receive enough oxygen, which is called hypoxia.

于是冠脉B供血肌出现缺血，肌细胞无法获得足够气，称为“缺”。
