With the development of technology, more and more people begin to use oxygen masks. The oxygen mask is a comprehensive mask made of plastic. It is a simple tool that provides oxygen to patients who need it. It connects the mask to the oxygen tank via a thin tube and places the disposable oxygen mask on the patient's complex so that the patient can get oxygen in the event of life-threatening breathing difficulties. So what types of oxygen masks are there?

1. Simple oxygen mask: The oxygen concentration in an ordinary room is about 21%. Oxygen masks are suitable for medical oxygen masks with an oxygen concentration of 30%-60%, usually made of plastic. These oxygen masks are attached to the patient's mouth with a flexible headband. A simple medium-concentration oxygen mask, for example, has holes to allow carbon dioxide to escape and fresh air to mix with oxygen.

2. Oxygen storage masks: These oxygen masks have gas storage tanks. Non-breathing oxygen masks and partially rebreathing oxygen masks fall into this category. The cover plate is used to deliver high concentrations of oxygen. Some rebreathing oxygen masks, such as the Hudson RCI Adult High Concentration Oxygen Mask, provide 70% to 90% oxygen, while non-rebreathing oxygen masks provide more than 90% oxygen. Oxygen storage masks do not have any openings to restrict the flow of outside air. Oxygen storage masks can be divided into three specific uses.

a. Military aviation oxygen mask: It is mainly used by pilots, because the higher the plane, the greater the atmospheric pressure outside the plane, and the oxygen in the cabin will be less and less. At this time, the pilot needs to breathe through the oxygen mask to reduce his own hypoxia. Aviation oxygen masks are the primary personal protective equipment for pilots and the key to the human-machine interface. It is most frequently used in actual flight and is closest to the human body. Its protective performance plays a very important role in ensuring the oxygen supply and survival of pilots in high-altitude flights. Aviation oxygen masks play an immeasurable role in avoiding the threat of high-altitude hypoxia and ensuring flight safety!

b. Civil aviation oxygen mask: mainly used in civil aircraft. When the plane takes off, the atmospheric pressure outside the cabin has a pressure effect, and the cabin will be subject to atmospheric pressure. As the plane ascends, the oxygen will become thinner and thinner, and passengers will experience dizziness, nausea, and other handling symptoms. At this time, an oxygen mask is needed to maintain the life and health of the patient.

c. Medical oxygen mask: The oxygen storage system consists of a mask, an oxygen storage bag, a T-shaped tee, an oxygen delivery tube, and fixed parts. Mainly used for cerebral hypoxia, and indigestion patients. Oxygen is injected directly into the oxygen storage bag, and the mask is placed on the patient's face with the mouth and nose closed. Attach the mask to the patient's head using the securing member and inhale oxygen.
