Bab 341: Chapter 342: Love Rival, ??

One after another, several patients refused oxygen therapy, leaving even Zhang Shu and Chen Cang perplexed.

Tian Cong was also quite curious, and couldn't help but ask, "Doctor, can oxygen actually be toxic?"

Zhang Shu glanced at Tian Cong and said, "Oxygen is indispensable, as it's present in the air, but the concentration of oxygen is very important. When the partial pressure of oxygen exceeds half an atmosphere, it starts to become toxic to cells. Under one atmosphere, humans can survive for up to 24 hours maximum, and in an environment of three atmospheres of oxygen, humans can die within minutes."

At this point, all the patients were baffled!

Oxygen therapy can be like this?

They thought more oxygen was always better!

It seems that this is not the case.

Looks like in the future, we'll have to pinch our noses when we go out... in case of oxygen poisoning...
