Introduction
The difference between pure oxygen and medical oxygen lies in their uses, the substances they contain, and their potential harm to the human body. In addition, it should be noted that the use of medical oxygen must be conducted under a doctor's guidance, as excessive oxygen may cause bodily harm. Meanwhile, medical oxygen also carries certain side effects and risks.
Pure oxygen and medical oxygen differ in their applications, constituent substances, and potential harm to the human body.
1. Different Functions
Medical oxygen is oxygen separated from air via low-temperature separation methods and is intended for medical use and patient treatment. Pure oxygen, on the other hand, is commonly used for general industrial purposes.
2. Different Constituent Substances
Pure oxygen is considered acceptable if its impurity content exceeds 99%. In contrast, medical oxygen has high purity, with an oxygen concentration of no less than 99.5%, and is colorless, odorless, and free of harmful impurities.
3. Effects on the Human Body
Medical oxygen poses no harm when used appropriately. However, pure oxygen may contain significant amounts of impurities and harmful gases that can damage the upper and lower respiratory tracts. Damage to the nasal mucosa may result in symptoms such as runny nose. Injury to the lower respiratory tract can cause swelling of the respiratory mucosa, airway spasms, breathing difficulties, and hypoxemia.
In addition, it should be noted that medical oxygen must be used under a doctor's supervision, as excessive oxygen intake may harm the body. Medical oxygen also carries certain side effects and risks, such as oxygen toxicity and pulmonary oxygen toxicity, and therefore should only be administered under medical guidance.
