Steps for nasal cannula oxygen administration

Generally, nasal cannula oxygen therapy refers to administering oxygen through a nasal cannula, which helps correct hypoxia in patients, maintain normal blood oxygen partial pressure and oxygen saturation, and promote the body's metabolism. The specific procedure is as follows:

1. Check the patient's nostrils for any foreign objects and ensure they are unobstructed.

2. Use a cotton swab dipped in normal saline to clean the patient's nasal cavity.

3. Gently insert the nasal cannula into the patient's nostril until it fits comfortably inside the nasal passage.

4. Secure the nasal cannula to the head using a nose clip or soft foam fixation device to prevent dislodgement or displacement.

5. Connect the nasal cannula to the oxygen tubing, turn on the oxygen cylinder or oxygen generator, test whether oxygen is flowing, and then adjust the oxygen flow rate accordingly.

6. Monitor the patient's response; if discomfort occurs, make immediate adjustments.

Nasal cannula oxygen therapy is a relatively safe and non-invasive method of oxygen delivery. However, it is recommended to undergo this treatment at a正规 medical facility under the guidance of a qualified healthcare professional. If any discomfort or abnormal symptoms occur during use, stop oxygen administration immediately and seek prompt medical attention for professional advice.
