Here I have a pulse oximeter attached to my finger.

在无名指上夹了一个仪。

We have to check for patients. We bring them oximeters, take their daily readings.

们得检查病人。们给他们带，量他们每日的读数。

More than 1 million finger pulse oximeters have been distributed to village clinics across the country.

100 多万台指脉仪已分发到全国各地的乡村诊所。

My pulse oximeter hasn't gone past 99%, but people doing the Wim Hof method have increased their blood oxygen saturation to 100%.

的结果没有超过 99%，但采用了 Wim Hof 呼吸法的那些人，其饱和度达到了 100%。

And then the sensor in the pulse oximeter can then calculate how much blood oxygen there is based on that confirmation of hemoglobin.

然后脉搏仪中的传感器可以根据红蛋白的确认算出有多少。

So this pulse oximeter you can wear on your finger shoots infrared light from one side and has a sensor on the other, and you've gotta put it on a part of thin skin.

你可以戴在手指上的这个脉搏仪从一边发射红外光，另一边有一个传感器，你必须把它戴在薄薄的皮肤上。
