The OXYGEN MASK is a medical device used to deliver oxygen directly to the patient through the mouth and nose. It is connected to an oxygen tank or an oxygen concentrator via a tube, enhancing the oxygen flow to the lungs. It is commonly used in hospitals or emergency settings to treat patients with oxygen deficiency, such as those with asthma, bronchitis, or other lung conditions. The mask is typically made of flexible plastic, with straps to secure it comfortably to the face, and comes in various sizes for both children and adults.
