1, the use is not the same
Medical oxygen: refers to the use of deep cold separation method will be separated from the atmospheric oxygen in order to supply the medical treatment of patients using oxygen;
Industrial oxygen: industrial oxygen is mainly used for gas flame processing and other industrial purposes;
2, containing substances are not the same
Medical oxygen: basically pure oxygen, high quality.
Industrial oxygen: low quality requirements, containing carbon monoxide, carbon dioxide, acetylene and other harmful impurities.
3, whether the human body harm
Medical oxygen: no harm.
Industrial oxygen: impurities and harmful gases in industrial oxygen can cause damage to the upper and lower respiratory tract. Nasal mucous membrane damage will run clear nose; lower respiratory tract damage can cause respiratory mucous membrane edema, airway spasm, resulting in poor ventilation, respiratory distress, hypoxemia.

Effects on the human body
Prior to 1988, China's medical oxygen were produced by the oxygen plant using a deep-cooling method of separating the air in accordance with the "industrial gaseous oxygen" standard of industrial oxygen production.
With the growing development of medical and health care in China and the continuous improvement of people's health level, the quality of medical oxygen requirements are constantly improving, continue to contain free water, halogens and other harmful impurities of industrial oxygen for medical and health care, obviously does not meet the requirements of human health.
To this end, on April 12, 1988, the General Administration of National Standards promulgated GB 8982-1988 "Medical Oxygen" national standard, and on December 1, the same year began to implement.
The standard stipulates that the oxygen content of medical oxygen ≥ 99.5%, while water, carbon dioxide, carbon monoxide, gaseous acids and bases, ozone and other gaseous compounds content and odor regulations.GB8982-1998 "Medical Oxygen" national standard retains this provision;
But in the wording and references to slightly different: "This standard applies to gaseous and liquid oxygen produced by the low-temperature method of separating air". The substance of the content is the same. China from the founding of the country, has been compiled seven editions of the Chinese Pharmacopoeia, are required to medical oxygen containing O2 shall not be less than 99.5% (ml/m1).
After 2000, the production of medical oxygen in China into the scope of license management, September 12, 2008, the State Food and Drug Administration issued "medical oxygen business enterprises (wholesale) acceptance criteria" for comment (Food and Drug Administration city letter [2008] No. 117).
From the point of view of human respiratory physiology, the human body can not carry out metabolism without oxygen, hypoxia is harmful to the human body, severe hypoxia will be life-threatening. However, if a normal person inhales pure oxygen for a longer period of time, not only is it not beneficial to the human body, but it may cause oxygen toxicity.
In order to prevent oxygen toxicity caused by inhalation of "pure oxygen" in the process of rescue and treatment, all the ventilators and anesthesia machines are adjusted to 2l-90% of the range of oxygen content.
Industrial oxygen quality requirements for the preservation, filling, use of oxygen is relatively low, in the compression and filling process, there may be acidic or alkaline lubricating water into the cylinder. Patients inhaling industrial oxygen with more impurities may experience respiratory irritation such as choking and coughing.
