Oxygen ~ Facts About Your Cannulas
A nasal cannula is the flexible plastic device with two short tips or prongs that fit into your nostrils. It is used to administer low to moderate oxygen concentrations through your nose.
With the humidifier, tubing and cannula connected, set the oxygen flow at a low rate. Insert the tips of the cannula in the nostrils. Slip the two smaller plastic tubes over the ears and down under the chin. Adjust the plastic slide until the cannula fits snugly but comfortably. Clip the tubing to the clothes to allow enough slack for comfort and to allow turning the head. Adjust flow up to the rate prescribed by the doctor.
- A nasal cannula should always be worn with the prongs curved toward you.
- You do not have to always breathe through your nose when using a nasal cannula. The continuous flow of oxygen will collect in the space in your nose and throat. Then each time you inhale, you breathe this collected oxygen into the lungs.
- The flowrate prescribed by your doctor is set on the flow meter of your oxygen system. DO NOT increase the flow rate to compensate for longer tubing. If an adjustment is needed, it will be made by your respiratory therapist.
- If your nose becomes irritated from wearing the nasal cannula for long periods of time, you may want to use a water-based lubricant inside your nostrils. It may be helpful to consult your doctor or pharmacist, who can suggest a good water-based preparation. DO NOT use an oil-based product such as Vaseline.
- It is recommended that you change cannulas every two weeks to avoid possible contamination.
- Tubing to the cannula should be replaced monthly. If no humidifier is used, the tubing should be changed every three months.
