Although actually using an oxygen concentrator is not difficult, there are several
precautions a user must follow to use one safely and according to the doctor’s order.
The user should follow these steps to use a concentrator:
1. Plug the concentrator power cord into a properly grounded electrical wall outlet. Do
NOT use an extension cord.
2. Attach the cannula tubing to the concentrator’s oxygen output.
3. Turn the power switch to ON.
4. Adjust the flow adjustment knob to LOW.
5. Place the tips of the cannula in the nostrils. The tips should always curve toward the
user. Slip the two smaller tubes over the ears and down under the chin. Adjust the
plastic slide until the cannula fits snugly, but comfortably.
6. Adjust the flow knob to the rate prescribed by the doctor.
If the user’s nose becomes irritated from the cannula, he or she may want to use a
water-based lubricant in each nostril (an oil-based lubricant such as Vaseline should
NOT be used). The user’s doctor or pharmacist will be helpful in suggesting a water-
based lubricant.
The user should follow these steps to turn the oxygen concentrator off:
1. Remove the cannula.
2. Turn the power switch to OFF.
3. The flow control knob does NOT need to be turned OFF. It should be checked each
time the concentrator is turned ON and periodically while in use.

Maintaining Your Oxygen Concentrator
Intake filter – Twice each week, the intake filter should be cleaned. The sponge-like
filter should be removed and washed under running tap water. The concentrator should
NOT be used with the filter removed. The excess water should be shaken out, then the
filter should be pressed or squeeze dried with a clean towel. When the filter is dry, it
should be reinserted into the concentrator.
Concentrator – The outside of the concentrator should be wiped down with a damp
cloth periodically.
