Over time, a serious RSV infection can lead to hypoxemia which is a decreased oxygen content in the blood.

随着时间推移，严重的RSV感染可导致低氧血症，即血液中氧气含量较低。

Given that oxygen content in the atmosphere would remain the same, you would slowly start to choke from breathing the air.

有鉴于大气中氧气的含量不会改变，你会因为呼吸空气而渐渐开始窒息。

Over time, this can reduce the oxygen content to less than 2 milligrams of oxygen per liter, creating an uninhabitable dead zone.

随时间，这个现象可能会把水中的含氧量减少到低于每公升二毫克的氧气，造成不适居住的死亡区。

In summer, you may have lower risk of altitude sickness because the air has a higher oxygen content than in other seasons.

夏天游玩出现高原反应的风险较低，因为空气中的氧气含量高于其他季节。

They'd know you just added it because the oxygen content would be too high, and that's why it can't be forged.

他们会发现的因为氧含量会过高，所以伪造那酒是不可能的。

Increasing the blood's oxygen content is especially helpful for those with weak heart muscles who have difficulty pumping enough oxygen throughout the body.

增加血液中的氧气含量对于那些难以将足够的氧气输送到全身的心脏肌肉较弱的人特别有帮助。

That's right, even though an acid is defined by its ability to give up hydrogen ions, it is identified by it's oxygen content.

没错，尽管酸是由其释放氢离子的能力来定义的，但它是由氧含量来识别的。

" There was a lot of debate as to what the oxygen content was 800 million or more years ago, " said Nigel Blamey of Brock University's Department of Earth Sciences.

布鲁克大学地球科学系的奈杰尔·布兰梅（Nigel Blamey）称，“关于8到10亿年前的氧含量的议题存在大量争议。”

And so we have a number of key variables that we control: oxygen content, the light, the light intensity, the dose to cure, the viscosity, the geometry, and we use very sophisticated software to control this process.

氧含量、光、光的强度、凝剂剂量、粘度、形状结构。我们用非常精密的软件 来控制这个过程。
