Oxygen Mask

An oxygen mask is a medical device that is used to deliver oxygen to a person who is having difficulty breathing or is in need of supplemental oxygen. It is typically made of a flexible plastic material and covers the nose and mouth of the person wearing it. The mask is connected to an oxygen source, such as an oxygen tank or a wall outlet, through a tube. When the oxygen is turned on, it flows through the tube and into the mask, allowing the person to breathe in the oxygen-rich air. Oxygen masks are commonly used in hospitals, ambulances, and other healthcare settings, as well as in certain situations such as high-altitude flying or during scuba diving.
