To avoid inert gas narcosis, many divers fill their tanks with Heliox, which combines 21% oxygen with 79% helium.

为了避免惰性气体麻醉病症，许多潜水员会在水箱中注入一种氦氧混合剂，这可以将21%的氧气和79%的氦气混合在一起。

Below 25 meters, inert gases like nitrogen can trigger a condition called inert gas narcosis, which alters your central nervous system, leading to faulty judgment and hallucinations similar to the effects of an anesthetic.

在25米以下，像氮气这样的惰性气体会引发一种叫做“惰性气体麻醉”的病症，这种病症会改变人的中枢神经系统，会导致你出现错误的判断和幻觉，类似于麻醉剂的效果。
