What Are the Precautions for Nasal Catheter Oxygen Inhalation?

When using nasal cannula for oxygen inhalation, it is first necessary to adjust the flow rate of oxygen, ensure that the cannula is free of quality issues, and replace the nasal cannula in time. If the patient's nose is particularly dry or other conditions exist, it is important to keep the nasal cavity moist. For some severely ill patients who are unable to effectively oxygenate themselves, it is necessary to rely on nasal cannula for oxygen inhalation, with numerous precautions to be observed.

1. Adjust the flow rate: When using oxygen, adjust the flow rate of oxygen first, and then apply oxygen inhalation after the flow rate is adjusted. When stopping oxygen inhalation, remove the cannula first and then turn off the oxygen switch to avoid a large amount of oxygen suddenly rushing into the respiratory mucosa if the switch is turned on incorrectly, which may cause damage to the lungs and trachea.

2. Keep the nasal cavity moist: For symptoms such as nasal dryness and erosion, regularly administer compound menthol nasal drops to the patient to keep the nasal cavity moist and prevent bleeding caused by dry nasal mucosa.

3. Ensure the proper use of the cannula: It is necessary to observe whether the cannula is unobstructed and in place during use. Regularly observe whether the patient shows signs of hypoxia, whether there is any leakage in the oxygen device, etc. For patients who require long-term oxygen inhalation, it is important to observe the nasal cannula and replace it regularly. If any problems are found, promptly report them to the doctor.
