Dingri County, Xigaze City, Tibet, is located at the foot of the mountain in the middle of the Himalayas, the average altitude is nearly 4,000 meters,the oxygen content is only 60-70% in the plain area... This is a true portrayal of the harsh environment of Zada County in Ali Region, Tibet. This is also the place where the Songjiang Tibet Aid Group has been assisting Tibet since 1995. The high altitude and low air pressure here are a great test of the physical endurance of the people in Tibet. Knowing that the local working and living conditions are difficult, with the support of the Shihudang government, Baobang donated four civilian cámaras hiperbáricas de oxígeno to the local government to support Shanghai's aid to Tibet.

This city is one of the most remote counties with the longest border line in Tibet, a large number of aspiring people flocked to participate in the construction. They have different identities, including civil servants serving the people, army soldiers with a mission... However, they face similar difficulties: lack of oxygen and low pressure in Tibet, which often cause headaches, vomiting and difficulty breathing symptoms.

80% of the people who go to the plateau will have altitude sickness. The most fundamental reason for high reaction is that "oxygen partial pressure is too low" and "hypoxia". In the plateau area of 3000 meters above sea level, the oxygen content of air is about 66% of sea level, and in the plateau area above 5000 meters, the air oxygen content is only 52% of sea level. Therefore, people living in the plain areas go to the plateau, because of hypoxia and occur altitude sickness. People who have lived in the plateau for a long time are not immune.

As a direct and effective way to alleviate altitude sickness, high-pressure oxygen inhalation has become an essential part of everyone's daily life.

Working principle of the civil hyperbaric oxygen chamber

The solubility of oxygen in the liquid increases with the rise of the pressure. The working principle of the civil cámara de oxígeno hiperbárico uses the pressure pedal power equipment to increase the pressure in the cabin. At high altitudes, increasing the air pressure in the cabin is equivalent to lowering the altitude, which can increase the oxygen content in the user's blood. When altitude sickness occurs, the advantage of using a civil hyperbaric oxygen chamber over oxygen cylinders is that not relying on oxygen cylinders, not adding additional oxygen, and rapidly decreasing height is the only and safest way to relieve symptoms. The use of civil hyperbaric oxygen chamber can drop to a safe height of 2000 meters to improve the user's symptoms and play the role of health care.

Oxygen Star 1 also has many users from the high Tibet Plateau area, and recently received feedback from customers in Zhongba County, Xizang Province. The customer said that the civil hyperbaric oxygen capsule can not only relieve the discomfort of altitude sickness, but also provide daily health care.
