The first element of human existence is oxygen. Without the support of oxygen, human beings will cease to exist. Therefore, oxygen is the basis for human survival on earth.
In clinical medicine, oxygen masks are mainly used to connect with breathing equipment to deliver oxygen to patients.
For some areas with thin air and high air pressure, the oxygen content is very low. Humans usually suffer from chest tightness, shortness of breath, dyspnea, dizziness and other symptoms of hypoxia. At this time, certain oxygen equipment is often needed to help breathe smoothly, that is, an oxygen mask.
When passengers experience hypoxia symptoms such as difficulty breathing, chest tightness and shortness of breath during air travel, they can use the aircraft's emergency oxygen mask.
In summary, oxygen masks are suitable for high-altitude, high-altitude areas, civil aviation, and clinical medicine. It has an important role in assisting the treatment of diseases and protecting personal safety.
