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

我们呼吸的空气大约是 21%。

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

最，你的血液温度升高，血细胞内的会减少。

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

阿布迪医生说，他体内的已经降到了60%。

40. And her 02 sats are dropping fast.

40 她的饱和度在急剧下降。

Due to the city's high elevation of a mile and a half above sea level, its oxygen levels are 25% lower when compared to a city that is precisely at sea level.

由于这座城市海拔 1.5 英里，与恰好处于海平面的城市相比，它的要低 25%。

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

时间，这个现象可能会把水的减少到低于每公升二毫克的气，造成不适居住的死亡区。

One likely explanation is that an infection could change how much-oxygenated blood gets to certain regions of the brain involved in processing sensory input.

一种可能的解释是，感染可能改变大脑参与处理感觉输入的某些区域的血液。

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

这时，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。

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，当患者血液的开始下降时，要帮助患者呼吸。

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，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.

低水平可能迫使鲸鱼的猎物升至海面，因为海面的更为充足。

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

有适当的血液流向你的听力细胞时才会拥有健康的听力。

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

这些沉积物是缺的或很低的，并且它们充满了硫化氢。

An artery is your oxygenated blood.

动脉是的血液。

His oxygen level was up to 90 percent.

他的高达90%。

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

既然来了更多高的血液，患者右心室和肺动脉的饱和度就升高了。

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

大约25亿年前，细菌开始适应生活在丰富的环境。

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

血饱和度是衡一个人血液的指标。

K so deoxygenated blood comes from the body to the right atrium, and flows down into the right ventricle, where now it can either be pumped out to the lungs, as normal, or pop over to the left ventricle.

少的血液从身体流向右心房，然向下流向右心室，接要么如正常一样泵往肺部，要么“溜”到左心室。

In the warehouse they're bagged and sealed – this three inch fish in about a pint of oxygenated water. A gallon, as some legislation would require, could increase shipping costs eight-fold, Nahacky estimates.

在仓库里，他们被装袋和密封——这三英寸的鱼在大约一品脱的水。Nahacky估计，正如一些立法所要求的那样，每加仑汽油可能会增加八倍的运输成本。
