Frequently Asked Questions & Troubleshooting

Oxygen therapy can raise a lot of questions, especially if you're new to using oxygen equipment. To help you feel more confident and comfortable with your treatment, we've compiled answers to some of the most frequently asked questions about oxygen therapy. Whether you're wondering about daily usage, traveling with your equipment, troubleshooting issues or how to properly maintain it, we've got you covered. Below are the answers to some common questions.

Homefill

How do I operate my Homefill equipment?

The filling process must be completed in a specific order:

1. Make sure tank valve is closed.
2. Turn the concentrator on and make sure liter flow is **3 or less**. It cannot be 3.25.
3. Attach the tank to the homefill compressor.
4. Turn on the homefill compressor.

Please note that the tank needs to be at least halfway empty before the Homefill compressor will add more oxygen.

My homefill is indicating low oxygen. How do I fix this?

A low oxygen indicator is normal during the warm-up period. Please allow 4-5 minutes for the concentrator to warm up, then follow these steps to turn on the compressor:

1. Make sure tank valve is closed.
2. Attach the tank to the homefill compressor.
3. Turn on the homefill compressor.

If the issue persists, please contact us for further assistance.

Oxygen Concentrator

My concentrator is indicating low oxygen. How do I fix this?

To ensure proper operation of your concentrator, please follow these steps:

1. During the initial warm-up period, the concentrator may display a yellow indicator. This process may take up to 15 minutes, after which the indicator should switch to green.
2. Check the flow meter to see if it is set correctly. A setting too high or too low can cause an alert. Adjust the flow to your prescribed rate.
3. Inspect the air inlet, if applicable. A clogged or dirty inlet may also cause an alert.

If these steps do not resolve the issue, please contact our Virtual Service Call Center for further assistance.

There is no flow. How do I fix this?

There could be a few possible reasons why your oxygen concentrator isn’t flowing, so let’s go through some troubleshooting steps.

• First, double-check that the unit is plugged in and the power switch is turned on.
• Next, verify that the ball for the flow meter rises to the liter flow that it has been set at and is properly adjusted.
• If there’s a humidifier attached, remove the bottle, separate the top from the bottom, and carefully reattach them.
• Also, check the tubing for any objects sitting on it or kinks blocking the flow; if you find any, remove the blockage. If the tubing is permanently kinked, it may need to be replaced.

If the issue persists, please contact us for further assistance.

My unit is alarming. What should I do?

If you notice any lights or alarms on your oxygen concentrator, begin by identifying the type of light or alarm.

• A yellow light with the unit still running typically indicates that the external filter or grid may need cleaning. Please clean the external filter, but do not attempt to clean any internal filters.
• If there is a red light and the unit is alarming while still running, it may signal a flow issue, so check if the flow meter is set too high or too low and adjust it to the correct flow rate. 
• Additionally, check if you can hear the compressor running. Ensure the unit is operating and that the lights are coming on. If the unit isn't functioning, check both the circuit breaker on the device and the power outlet. Confirm that there is power to the outlet and that the electricity in the home hasn't gone out; it’s also possible that a circuit breaker may have tripped. Always remember to plug the unit directly into a wall outlet, not an extension cord, for optimal safety and performance.

These steps should help address common alarm and light indicators on your concentrator. If the problem persists, please reach out to a live representative for further assistance.

How do I remove water in my tubing?

Water in the tubing can occur, especially during colder seasons, as the warm oxygen from the concentrator picks up moisture in the water bottle, which may condense into droplets when it reaches a cold surface.

To minimize this, you can reduce the water level in the humidifier, add a water trap to the tubing, keep the tubing off the floor, shorten the tubing, or remove the humidifier daily and connect the tubing directly to the machine for 30 minutes to dry it out while still using the device.

My concentrator is making a weird noise or vibrating. How do I fix this?

Your oxygen concentrator might make noise and vibrate on certain floors. Please try moving the machine to a different floor area.

Do you have to come refill the concentrator with oxygen?

No, we do not need to refill the concentrator since this device extracts oxygen from the surrounding air and concentrates it to a therapeutic level.

Do I need a water bottle?

A water bottle is generally not required for oxygen levels of 3 or lower but can be prescribed if necessary.

Portable Oxygen Concentrator (POC)

My POC won't turn on. How can I fix this?

If your portable oxygen concentrator won’t turn on, there could be a battery issue.

• First, check that the battery is properly attached.
• If it’s not turning on, the battery may need charging. Connect it to a power source and confirm that it shows as charging. If it is, let it charge for a few minutes, then try turning on the concentrator again.
• If it still won’t run, the battery connection may need to be reestablished. To do this, remove the power supply, nasal cannula, and cover, then take the battery out by using your thumb to slide down the blue button and sliding the bottom of the device in the direction of the button—avoid pulling the battery directly down. Leave it disconnected for at least 60 seconds before reattaching it, allowing the lock to engage automatically. The unit may briefly turn on and off, which is normal.
• Finally, press the power button to turn on the portable oxygen concentrator.

I see a yellow triangle symbol on my POC. What does this mean?

If you see a triangle symbol with another icon next to it, identify the specific icon for further action:

• A nasal cannula symbol means a breath has not been detected for 15 seconds. Be sure to breathe through your nose, not your mouth, and check the cannula for kinks or leaks.
• A thermometer symbol indicates the machine is too hot or cold. Allow it to reach room temperature
• A low battery symbol signals the unit will shut down soon. Charge it or plug it into a power source
• A low oxygen symbol (down arrow) means there is a concentration issue. Please contact your supplier for a replacement.
• An airflow symbol suggests you’ve exceeded the maximum breathing rate of 40 BPM (breaths per minute). Please find another oxygen source until your breathing rate decreases.
• If a telephone symbol appears, please contact Medical Service Company's Virtual Service Call Team.

My POC battery does not last long enough. What should I do?

Your portable oxygen concentrator's battery life is dependent upon your prescribed setting. To extend the duration, it is recommended to purchase an additional battery.

Can I charge the POC in my car?

Yes, if the POC is set to pulse dose settings 1-3, it will charge while plugged into your car’s "cigarette lighter style" outlet. At settings of 4 or higher, it will maintain the current battery level.

What if my car doesn’t have a “cigarette lighter style” outlet; how do I charge the POC?

Currently, there are no charging options via a USB outlet. You may consider consulting a mechanic to install an inverter in your vehicle.

Why is my POC beeping?

The POC will emit a beep along with warning symbol that will be displayed on the main screen. Please consult the unit’s manual for troubleshooting or contact the Virtual Service Call Team for assistance.

Oxygen Cylinder

Why do I need an oxygen cylinder if I have a concentrator and a POC?

The cylinder serves as a backup system in case of a power outage or equipment failure.

Where should I store the oxygen cylinder?

Cylinders can be stored either vertically or horizontally, ensuring they remain secure and stable. If stored vertically, they should be placed in a stand or chained to a wall for safety, and they can also be nested upright. Always keep cylinders in a well-ventilated, clean area away from gas and oil, such as a garage, and avoid enclosed spaces like closets.

Other

Can I sit near a fireplace while using my oxygen?

It’s recommended that you and the oxygen equipment maintain a minimum distance of 7 feet from any open flames or heat sources.

How long do I need to use this oxygen?

The duration for which you need to use oxygen will be determined by your physician based on your specific health condition and needs. Your doctor will assess your progress and may adjust the length of time you need to use oxygen therapy accordingly. Regular follow-up appointments will help ensure that you are receiving the appropriate level of oxygen for as long as necessary.

Do I need to use oxygen while using my CPAP?

Whether you need to use oxygen with your CPAP device depends on your specific medical condition and should be determined by your physician. Some patients may require supplemental oxygen with their CPAP, especially if they have certain respiratory conditions. Please consult your physician to discuss your needs and receive guidance on whether to use oxygen with your CPAP.

How often will I receive new supplies?

We recommend replacing home cannulas every two weeks, home tubing every 90 days, and portable cannulas every 90 days, or as requested.

What supplies do I receive with my initial order?

Your initial order will include:

• 7 Nasal Cannulas
• 2 25-foot tubing
• 2 Swivels

The machine is loud; can I place it in a closet?

No, it is not recommended to place your oxygen machine in a closet. Oxygen concentrators require adequate ventilation to function properly and to prevent overheating. Placing the machine in a well-ventilated area, away from walls, drapes, or other obstructions, will ensure optimal airflow and safe operation.

Can I shower while using my oxygen?

For patients prescribed continuous oxygen, it is safe to wear the cannula while showering. The flow of oxygen should prevent water from entering the tubing. To minimize the risk of tripping, the tubing can be draped over the shower rod.

If I’m out of breath, can I increase the oxygen flow?

If you’re feeling out of breath, do not adjust the oxygen flow rate on your own. The flow rate has been set by your physician based on your specific needs. If you feel that the current flow isn’t sufficient, please consult your physician for guidance. Adjusting the flow rate without medical advice may not provide the proper therapeutic benefit and could affect your health.

Is it safe to use a hair dryer while using oxygen?

It is not safe to use devices like hair dryers, electric razors, heating pads, or heating blankets while using oxygen. These items produce heat or may create sparks, which can be hazardous in the presence of concentrated oxygen, significantly increasing the risk of fire. Always turn off your oxygen equipment and move to a well-ventilated area before using any heat-producing or electrical devices.
