oxygen mask

    An oxygen mask is a medical device that is used to deliver oxygen to a patient's lungs when they are having difficulty breathing on their own. The mask fits over the patient's nose and mouth and is attached to a source of oxygen. It is commonly used in emergency situations such as during a respiratory or cardiac arrest, or in cases where a patient is experiencing severe respiratory distress. Oxygen masks come in different sizes and designs to suit different patient needs and scenarios. They are an essential tool in the management of respiratory failure and other serious medical conditions.
