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

我自测的结果没有超过 99%，但采用了 Wim Hof 呼吸法的那些人，其血氧饱和度达到了 100%。

Even though my blood oxygen saturation stays at 99% and doesn't change, I do start to feel a bit of pressure in my head and tingling in my legs and fingers.

尽管学氧饱和度保持在 99% 不变，我渐渐感觉到头部有些紧，腿和手指上也开始出现轻微的刺痛感。
