Troubleshooting Oxygen Concentrators and Portable Oxygen Systems

1. My oxygen concentrator has a bright red light on and a loud continuous buzz or whistle is emanating from the unit. What should I do?
2. My oxygen concentrator has a loud continuous buzz or whistle emanating from the unit and it isn't working at all. What should I do?
3. My oxygen concentrator has a yellow/amber warning light on but no alarm is sounding. What does this mean and what should I do?
4. My concentrator has a warning light and alarms for a few minutes when I turn it on, then it goes away. What is this?
5. My oxygen machine is on, and there are no warnings, but the flowmeter ball won't come up to the setting my doctor prescribed. It worked fine last night, what happened and can I fix it?
6. I keep getting water in my oxygen tubing, why is this?
7. I changed the regulator from my old oxygen cylinder to a new cylinder and now it hisses really loud and leaks. Why is this?
8. I'm not sure oxygen is coming out of my nasal cannula, how can I test it?
9. Which way do I turn the handle or key to open my oxygen cylinder?
10. My cylinders don't last long enough for me when I am out of the house. What can I do to improve this situation?

1. My oxygen concentrator has a bright red light on and a loud continuous buzz or whistle is emanating from the unit. What should I do?

• First place yourself on an oxygen cylinder for continued therapy.
• Then turn off your concentrator and contact your provider immediately. The unit has failed and needs service.

2. My oxygen concentrator has a loud continuous buzz or whistle emanating from the unit and it isn't working at all. What should I do?

• You probably have a power failure or poor electrical wall connection.
• First place yourself on an oxygen cylinder before troubleshooting your system.
• Be sure the concentrator is plugged all of the way into the electrical outlet on the wall.
• Be sure that outlet is not wired to a light switch that is turned off. If that is the case, find an outlet that is not wired to a switch to prevent a recurring problem.
• You may have a poor functioning electrical outlet, try a different outlet. Try plugging a different device into that outlet to see if that unit works.
• Is your concentrator plugged into a multi-strip with an electrical switch that has been turned off? Never use an oxygen concentrator with any type of extension cord, it should always be plugged directly into your wall outlet.
• If unresolved, contact your provider immediately.

3. My oxygen concentrator has a yellow/amber warning light on but no alarm is sounding. What does this mean and what should I do?

• Your machine has a safety device on it called an Oxygen Percentage Indicator (OPI) and the yellow/amber light indicates that the oxygen purity is not up to specifications.
• First place yourself on an oxygen cylinder to continue your therapy.
• Clean your filter in the back or on the side of the unit. It most likely is dirty and the dust is significantly blocking airflow into the concentrator.
• Check to be sure there are no curtains, paper, or other material stuck to the filter preventing airflow into the unit.
• If unsolved after 15 minutes of use, turn the machine off and contact your provider immediately.

4. My concentrator has a warning light and alarms for a few minutes when I turn it on, then it goes away. What is this?This is normal function and self-testing from the machine. Glad it is working well. It is safe to use your oxygen.

5. My oxygen machine is on, and there are no warnings, but the flowmeter ball won't come up to the setting my doctor prescribed. It worked fine last night, what happened and can I fix it?

• First put yourself on an oxygen cylinder to continue your therapy.
• There are a few simple causes and solutions to this problem and yes, you can fix it. This problem is caused by either a leak in the system, or blocked, crimped tubing.
• If you use a humidifier, either the jar is not twisted tightly to the cap, or the cap is not tightly secured to the threaded outlet from the concentrator.
• Be sure your chair or bed is not crushing or crimping the tubing.
• It is also possible that the flowmeter is faulty and your unit would then need to be serviced. Contact your provider immediately.

6. I keep getting water in my oxygen tubing, why is this?

• Most likely you have a humidifier that is overfilled. Try less water. You can still use the tubing if you want, it will dry out and it is not dangerous for you to use.
• This can also be due to excessive condensation caused by the warm oxygen flow in the tube contacting a cold tile floor, thus creating "rainout" in the tube. If you wish to blow it dry, hook up your wet tubing to your portable oxygen tank and blow out the water.
• For a continuing problem, a water trap can be installed easily in your tubing to prevent water from getting to your nose.

7. I changed the regulator from my old oxygen cylinder to a new cylinder and now it hisses really loud and leaks. Why is this?

• You have a leak at the regulator connection. When you changed the regulator, you probably dropped the small washer that fits between the outlet port of the cylinder "neck" and the regulator. It won't work without it. If you are unable to find this washer, contact your provider immediately.
• The other possibility is that the regulator is not installed properly, allowing for oxygen to escape. Re-seat the regulator and tighten the thumbscrew.

8. I'm not sure oxygen is coming out of my nasal cannula, how can I test it?

• Put the tips of your cannula in a glass of water; be sure your concentrator is on. If you see bubbles, oxygen is flowing through the cannula. If you don't, be sure all of your tubing is connected and that your humidifier, if you use one, is properly attached.
• If you are still not sure, place yourself on an oxygen cylinder and contact your provider immediately.

9. Which way do I turn the handle or key to open my oxygen cylinder?Counter clockwise will open the cylinder, clockwise will close the cylinder.

10. My cylinders don't last long enough for me when I am out of the house. What can I do to improve this situation?You may benefit from the use of an Oxygen Conserving Device that can be added to your portable oxygen cylinder system. There are several types available to you and you should contact your provider to have a Respiratory Therapist see you and assess whether you can successfully use one, and which type of device will best suit your needs. The assessment and device requires a prescription from your physician. Most insurance Providers will not pay for an oxygen conservation device.
