Do you really understand the application of high-purity helium gas?
Helium, high-purity helium
Experimental studies on the heart and nerve tissue have shown that high-purity helium gas has anesthetic properties similar to xenon gas, and the rare gas high-purity helium gas also reduces ischemia-reperfusion injury. Although the different mechanisms of organ protection induced by high-purity helium gas have not been fully elucidated, multiple signaling pathways have been identified to provide protection to the heart and the brain through different pre-processing and post-processing protocols. High purity helium gas also has effects on the lungs, immune system, and blood vessels.

Obviously, high-purity helium gas as a rare gas is biologically inert and exerts biological effects, but until today, this question remains open on how to mediate these changes. Due to its excellent properties and lack of hemodynamic side effects, high-purity helium gas is suitable for use in critically ill patients. This article reviews the effects of high-purity helium on cells, which may lead to new clinical strategies for tissue rescue of ischemia-reperfusion situations, both during the internal and external surgical periods.
The biological effects of high-purity helium gas are a very surprising phenomenon, because for more than half a century, people have been using this gas in diving operations. Due to the anesthetic effect of nitrogen in the air, breathing air for diving depth cannot exceed 60 meters, which greatly meets the need for depth in diving. Due to the almost no anesthetic effect of high-purity helium gas and its small molecular weight and respiratory resistance, it plays a particularly critical role in diving, especially in deep diving. We can even say that without high-purity helium gas, there would be no modern deep diving technology. The first reason for using high-purity helium for diving is that high-purity helium is a physiologically inert gas, which means there will be no chemical reactions. At the same time, long-term diving medical research believes that high-purity helium has almost no significant biological effects.
