Central Medical Oxygen System for Large Hospitals

One of the most crucial differences between the two types of oxygen supply systems, namely the oxygen diffusion system for high-altitude areas and the medical central oxygen supply system, lies in the purity of oxygen. The core of the oxygen diffusion system for high-altitude areas is to "increase the oxygen content in the space", rather than providing high-concentration pure oxygen. It is only necessary to control the oxygen content in the air within the space between 21% and 28.7% - this range is close to the oxygen content of the air at plain areas, which can effectively alleviate altitude sickness and avoid the risk of fire caused by excessive oxygen content (oxygen is a fuel supporter, and flammable materials are prone to intense combustion in a high-concentration oxygen environment). However, the "medical-grade purity" is a hard requirement for the medical central oxygen supply system. According to the national pharmacopoeia, the oxygen directly used for patient treatment must have a purity of over 99.5%, and it is necessary to remove water, impurities, carbon monoxide and other harmful components to avoid irritation to the patient's respiratory tract and lungs or the risk of infection.
