Oxygen is delivered to the face using a face mask, which is designed to fit over the nose and mouth.
Types of Oxygen Delivery Masks
A face mask is a common method of delivering supplemental oxygen. According to the reference, a face mask is:
a plastic, rubber or silicone mask that covers the nose and mouth.
Several types of face masks exist, designed for specific needs:
- Simple Face Mask: This basic mask delivers a moderate concentration of oxygen.
- Non-Rebreather Mask: This mask delivers a higher concentration of oxygen. It has a reservoir bag that collects oxygen and minimizes the mixing of exhaled air with the oxygen supply.
- Venturi Mask: This mask is precise and allows for control of the oxygen concentration.
- Partial Rebreather Mask: This mask uses a reservoir bag to conserve oxygen, similar to a non-rebreather mask, but a portion of the exhaled gas is reintroduced for each breath.
How a Face Mask Works
A face mask is fitted over the face and secured with straps or elastic bands, creating a seal around the nose and mouth. Oxygen flows from an oxygen source (e.g., an oxygen cylinder or wall outlet) through a tube and into the mask, allowing the patient to inhale the oxygen. The exhaled carbon dioxide exits through the mask's openings.
Summary of Face Mask Use for Oxygen Delivery
In summary, oxygen is delivered to the face by way of a face mask, which comes in various types for different needs, providing a direct route for oxygen to enter the lungs through the nose and mouth.
