We all breathe air that's around 21% oxygen.

我们呼吸的空气含氧量大约是 21%。

Finally, as your blood temperature increases, your blood cells actually hold less oxygen.

最后，随着你的血液温度升高，血内的含氧量会减少。

His oxygen level was up to 90 percent.

他的含氧量高达90%。

Oxygen saturation levels are a measure of the amount of oxygen in a person's blood.

血氧饱和度是衡量一个人血液中含氧量的指标。

40. And her 02 sats are dropping fast.

40 她的含氧饱和度在急剧下降。

Healthy hearing happens when there is a proper flow of oxygenated blood reaching your hearing cells.

有适当的含氧血液流向你的听时会有康的听。

These sediments were anoxic, or poor in oxygen, and they were also full of hydrogen sulfide.

这些沉积物是缺氧的或含氧量很低的，并且它们充满了硫化氢。

An artery is your oxygenated blood.

动脉是含氧的血液。

Around 2.5 billion years ago, bacteria began adapting to live in the oxygen-rich environments on Earth.

大约25亿年前，菌开始适应生活在含氧丰富的环境中。

The oxygen rate in his body had dropped to 60 percent, Dr. Abdi said.

阿布迪医生说，他体内的含氧量已经降到了60%。

Those heat waves lower the oxygen levels and make the environment really unsuitable for many of these life forms.

这些热浪降低了海水的含氧量，让环境变得不适宜很多生命形态生存。

The low oxygen levels might force the whales' prey towards the surface, where oxygen is a bit more plentiful.

低氧水平可能迫使鲸鱼的猎物升至海面，因为海面的含氧量更为充足。

By that she means helping a person to breathe when the oxygen levels in the patient's blood starts to drop.

她的意思是，当患者血液中的含氧量开始下降时，要帮助患者呼吸。

Now, deoxygenated blood is escaping out to the systemic circulation, and being pumped out to the whole body via the aorta.

这时，含氧少的血液逃到体循环去了，并且通过主动脉泵到全身各部位。

Since there's more oxygenated blood over here, patients will have an increased oxygen saturation in the right ventricle and pulmonary artery.

既然来了更多含氧高的血液，患者右心室和肺动脉的氧饱和度就升高了。

BUN and creatinine's rising. ALT and AST twice the normal range.

把她放在含氧40％的高压氧仓里直到她的血饱 和氧量和B.U.N.和肌氨酸酐数量增加。

Oxygen in the water increases and the fish crowd together.

冰下的含氧量提高，鱼群的密度会很大。

First, let's look at oxygen requirement in minimum oxygen zones.

首先，让我们看看最低含氧区的氧气需求。

The first and most familiar oxygen-based functional group is the alcohol, a terminal " -OH" .

第一个也是最熟悉的含氧官能团是醇，它有一个末端的“-OH”。

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。
