According to different use environments, oxygen masks can be mainly divided into three categories: one is military aviation oxygen mask: it is mainly used for pilots, because the higher the plane flies, the greater the atmospheric pressure outside the plane, and the oxygen in the cabin It will become thinner and thinner. This is why the pilot needs to breathe oxygen through the oxygen mask to alleviate his own hypoxia. One is the civil aviation oxygen mask: it is mainly used for civil aircraft, which is the aircraft that everyone usually rides on. When the aircraft takes off, the atmospheric pressure has a pressurizing effect on the outside of the aircraft, and the cabin will be pressurized by the atmospheric pressure. Oxygen will become thinner and thinner as the plane ascends, and passengers will experience symptoms such as dizziness and nausea. At this time, oxygen masks are needed to protect the patient's life and health. The last type is the medical oxygen mask: It is mainly suitable for patients with brain hypoxia and difficulty breathing. When using it, the oxygen mask is placed on the patient's face, closing the patient's respiratory organs and allowing them to breathe oxygen.
All in all, an oxygen mask is a full-face mask made of plastic. It is a simple tool to provide oxygen to patients who need oxygen. It uses a thin tube to connect the mask to the oxygen storage tank. When the patient's life-threatening breathing occurs, In case of difficulty, place an oxygen mask on the patient's entire face and allow the patient to breathe oxygen.
