Diffused oxygen supply refers to the simultaneous oxygen inhalation by multiple people in the same living environment.

Diffused oxygen supply is widely used in various indoor oxygen supply scenarios such as centralized office areas of enterprises and institutions in plateau regions, hotel rooms, and households. It is suitable for both alleviating symptoms of altitude hypoxia and for individuals undergoing oxygen therapy and health care. Diffused oxygen supply allows multiple people in the same living environment to inhale oxygen simultaneously, avoiding the restraint caused by nasal cannulas and oxygen masks, thereby improving the comfort of oxygen inhalation. People can replenish oxygen while engaging in other activities in an oxygen-enriched environment. Its drawback is that it consumes relatively more oxygen, and it takes some time to increase the oxygen concentration in the space.

The characteristics of plateaus include thin air, low atmospheric pressure, and low oxygen partial pressure. Under hypoxic conditions at high altitudes, lack of oxygen is the main cause of reduced work capacity in the human body and brain. The higher the altitude, the greater the impairment of physiological functions. Ordinary people often experience discomfort when working or living at high altitudes. At elevations above 4,000 meters, approximately 60% to 100% of people experience acute hypoxia reactions or illnesses, with common symptoms such as headaches, dizziness, palpitations, shortness of breath, loss of appetite, nausea, vomiting, abdominal distension, chest tightness, chest pain, fatigue, mild facial swelling, and dry, cracked lips. In severe cases, blood pressure may rise, heart rate may increase, and even coma may occur. Prolonged work and life at high altitudes can easily lead to serious altitude sickness, such as acute or chronic mountain sickness, high-altitude pulmonary edema, and high-altitude cerebral edema, which significantly impact physical and mental health.

Plateau diffused oxygen generators are primarily used in relatively enclosed areas of human activity. They directly diffuse oxygen to create an oxygen-enriched environment throughout the activity area, maintaining an oxygen concentration of 24% to 25%. The diffused oxygen supply method allows multiple people in the same living environment to inhale oxygen simultaneously, avoiding the restraint caused by nasal cannulas and oxygen masks, thereby improving the comfort of oxygen inhalation. People can replenish oxygen while engaging in other activities in an oxygen-enriched environment. Its drawback is that it consumes relatively more oxygen, and it takes some time to increase the oxygen concentration in the space. In recent years, the diffused oxygen supply method has been widely used in various indoor oxygen supply scenarios such as centralized office areas of enterprises and institutions in plateau regions, hotel rooms, and households. It is suitable for both alleviating symptoms of altitude hypoxia and for individuals undergoing oxygen therapy and health care.

Both diffused oxygen supply and nasal cannula oxygen inhalation methods can increase a person's blood oxygen saturation, with no significant difference in the oxygen-enriching effect.

In summary, plateau diffused oxygen generators are useful both in plateau regions and other areas. They play an essential role in safeguarding the health of people living in high-altitude regions.
