How is medical oxygen delivered to hospitals?

At present, medical oxygen is mainly delivered to hospitals by specialized oxygen supply stations, and some large hospitals have their own oxygen stations. If you are filling up oxygen for your family, you can go directly to the oxygen station or to the hospital. Oxygen stations are high-risk work environments, and are usually located in very remote areas that are not easy to find. If you need to use medical oxygen, it is recommended that you go to the hospital to fill it. Usually the emergency departments of various hospitals provide this service, although some of the larger hospitals only provide piped oxygen, which can be difficult to fill, and it is recommended that you go to a level 1 hospital to fill your oxygen.

Difference with industrial oxygen

Industrial oxygen is used for industrial production and product processing of industrial gases, the quality requirements are lower general requirements for the purity of 99% or more qualified. The filling procedure is not as strict as that of medical oxygen, and there are often water and other impurities mixed in and remaining in the oxygen cylinders. The water mixed in and remaining in the cylinders will lead to rusting on the inner wall of the cylinders, which will make the gas inside the cylinders with a peculiar odor. At the same time, industrial oxygen also exists in carbon monoxide, carbon dioxide, acetylene and other impurities that are extremely harmful to the human body, once the patient inhales too much, choking and coughing, crusting and other phenomena, triggering or aggravating respiratory system diseases.

Medical oxygen is commonly known as dry oxygen: the purity of medical oxygen requires more than 99.5%, in the production and filling process in addition to the removal of harmful gases to the human body, the main thing is to strictly control the water content of oxygen. Because medical oxygen is inhaled into the human body and widely used in medical treatment, so the drug regulatory authorities have been included in the medical oxygen to manage drugs, the production and operation of medical oxygen are required to obtain a license.
