OXYGEN MASK

• An oxygen mask is a medical device that covers the nose and mouth, providing a reservoir of oxygen to the patient. It allows for increased oxygen levels in the inhaled air, helps prevent CO2 rebreathing, and permits humidification of gases to reduce mucous membrane drying.
• Nasal cannulas and face masks are used to deliver oxygen to people who don't otherwise get enough of it. They are commonly used to provide relief to people with respiratory disorders. A nasal cannula consists of a flexible tube that is placed under the nose.
• Home oxygen therapy can be useful for people who do not have enough oxygen in their blood. It can help with conditions such as: chronic obstructive pulmonary disease (COPD) pulmonary fibrosis.
• To use oxygen therapy, you'll typically use a nasal cannula or face mask connected to a concentrator or tank, and the flow rate should be set as prescribed by your doctor.
