氦氧潜水是国防、经济和科学研究等方面完成水下任务的一种重要手段。用氦氧代替空气进行深潜水的主要原因有:在深海或高压下呼吸空气时,人对空气中氮和氧分压升高的耐受能力有一定限度,如超过氮的耐受限度(氮分压为4.8～5.6个大气压),会出现氮麻醉;

Heli-Oxygen diving is an important means of accomplishing underwater tasks in areas such as defense, economy and scientific research. The main reasons for deep diving with helium instead of air are: There is a limit to how well people tolerate elevated levels of nitrogen and oxygen in the air when breathing in deep sea or under high pressure, such as nitrogen, which exceeds the nitrogen tolerance Partial pressure of 4.8 to 5.6 atmospheres), there will be nitrogen anesthesia;
