How do I properly use a nasal oxygen cannula?

In general, the nasal oxygen cannula can be directly inserted into the nose for oxygen inhalation to avoid breathing difficulties. The specific operation steps are as follows:

1. Wash your hands with clean water before operation to avoid infection.

2. Check whether there are foreign objects in the patient's nasal cavity and whether the lumen is unobstructed.

3. After the inspection is completed, connect the oxygen meter to the oxygen cylinder and then to the humidifier bottle.

4. Inject an appropriate amount of sterile water, connect the nasal oxygen cannula, and check whether the nasal oxygen cannula is leaking.

5. After checking for leaks, insert the nasal oxygen cannula into the patient's nasal cavity.

6. Adjust the tightness of the nasal oxygen cannula to ensure that the patient is comfortable to wear.

7. After the adjustment is completed, turn on the flowmeter, adjust the oxygen flow, and ensure that the oxygen flow is unobstructed.

In the process of using the nasal oxygen cannula, try to avoid unnecessary pulling or collision to prevent the tube inserted into the nostril from falling off. If you need to wear an nasal oxygen cannula, it is recommended to go to a regular hospital and operate under the guidance of a professional doctor to avoid damage to the body due to improper operation.
