The gas emitted when the oxygen concentrator is used is not harmful.
The oxygen generator directly separates oxygen from the air. It is based on physical principles without any chemical changes. The gas eliminated is mainly nitrogen. The oxygen in the air accounts for 78% of nitrogen. In fact, we breathe it every day. Air, oxygen accounts for about 20%, and nitrogen is harmless to the human body. So it won't cause harm to people.
The purity of medical oxygen produced by the household oxygen generator is 93%±3, which is not pure oxygen. The outlet pressure is 0.04-0.05MPa. There is still some pressure loss when the oxygen is transported from the outlet of the machine to the oxygen suction pipe head, so it is very safe. However, the amount of oxygen inhaled and the length of oxygen inhaled time vary from person to person, whichever is better when the person inhaling oxygen feels good.
Extended information
Electronic oxygen generator
Electronic oxygen generators are more common in pharmacies. They use oxygen in the air to oxidize and reduce in solution. process, so it does not produce dangerous hydrogen like electrolyzing water to produce oxygen. The whole machine runs relatively quietly, but the requirements for handling and using this type of product are very strict, and tilting and inversion are never allowed, otherwise the solution will flow into the oxygen tube and spray into the nasal cavity, causing serious damage to the user.
Molecular sieve oxygen generator
Molecular sieve oxygen generator is an advanced gas separation technology. It extracts oxygen directly from the air by physical method (PSA method) and can be used immediately. , fresh and natural, the maximum oxygen production pressure is 0.2~0.3MPa (ie 2~3kg), and there is no danger of high pressure and explosion.
Chemical Oxygen Concentrator
Using a reasonable pharmaceutical formula, it can indeed meet the urgent needs of some consumers when used in specific situations. However, due to the simple equipment, troublesome operation, high cost of use, a certain amount of money required for each oxygen inhalation, and the inability to be used continuously, it is not suitable for home oxygen therapy.
Oxygen-enriched Membrane Oxygen Generator
This type of oxygen generator uses a membrane oxygen generator to filter nitrogen molecules in the air through the membrane to reach an outlet oxygen concentration of 30%. Small size, low power consumption and other advantages. However, the machine using this oxygen production method produces oxygen with a concentration of 30%, which can be used for long-term oxygen therapy and health care. However, the first aid required in severe hypoxia can only use medical high-concentration oxygen.
