1772年舍勒等发现了氧气。此后氧气主要用于冶炼工业的吹炼、化学工业的强化工艺、能源工业的液氧助燃及医疗。对工业用氧的质量要求是执行GB3863-83,检测时根据产品中水分的含量分为两类,按氧纯度又分为两级(99.5％、99.2％)。氧气在医学上主要用于缺氧等危急重病人的急救治疗和辅助治疗,常用的有高压氧和常压低氧。医疗用氧气作为治疗用品(包括瓶装和液态氧)被直接吸入人体内,对人体健康影响甚大。易对氧气纯度和卫生理化指标有严格规定,技术指标
In 1772, Scheler discovered oxygen. Since then oxygen is mainly used in the smelting industry, blowing, strengthening the chemical industry processes, the liquid oxygen industry, energy and medical support. The quality requirements of industrial oxygen is the implementation of GB3863-83, testing the moisture content of the product is divided into two categories, according to the oxygen purity is divided into two levels (99.5%, 99.2%). Oxygen in medicine is mainly used for first aid treatment and adjuvant therapy for critically ill patients such as hypoxia. Hyperbaric oxygen and atmospheric hypoxia are commonly used. Medical oxygen as a therapeutic (including bottled and liquid oxygen) is directly inhaled into the human body, has a great impact on human health. Easy to oxygen purity and health and physical and chemical indicators have strict rules and technical indicators
