Understanding the Signs of Proper Function
For many, oxygen therapy is a lifeline. Ensuring your equipment is functioning correctly is essential for receiving the full benefits of your treatment. From the sounds your machine makes to the way your body feels, there are several indicators that can help you determine if your oxygen is working as it should.
Visual and Auditory Indicators
Your oxygen concentrator provides several clear signals about its operational status. Becoming familiar with these cues is the first step in confirming everything is running smoothly.
The Device's Display and Lights
- Green Light: A steady green or power-on light is the primary sign that your concentrator is powered and functioning. It indicates that the machine has initiated its startup process and is producing oxygen.
- Yellow Light: A yellow or amber light often indicates a low-purity warning. This means the oxygen concentration being delivered is not at the optimal level. This could be caused by dirty filters, a kink in the tubing, or a more serious internal issue.
- Red Light or Alarm: A red light, often accompanied by a loud, constant or intermittent alarm, signals a critical problem. This could be a power failure, a significant drop in oxygen purity, or a system malfunction. In this case, you should immediately switch to your backup oxygen supply.
The Sounds of an Operating Concentrator
- Normal Sounds: A properly functioning concentrator will emit a consistent, low humming or whirring sound from its compressor. You may also hear a gentle hissing sound as the oxygen flows through the tubing. These are normal operating noises.
- Abnormal Sounds: Listen for unusual sounds like rattling, grinding, or banging. These noises can indicate a mechanical problem, such as a loose part or a worn-out component. A loud, repetitive alarm is a clear sign of a system error that needs immediate attention.
Checking Oxygen Flow with a Simple Bubble Test
If you have an oxygen concentrator with a humidifier bottle, a straightforward bubble test can confirm that oxygen is flowing through the system. This is a non-technical method that can be useful if you're uncertain about the flow.
- Detach the nasal cannula from the concentrator's oxygen outlet.
- Fill the humidifier bottle with distilled water to the recommended level.
- Submerge the open end of the oxygen tubing into a glass of water.
- Turn on the concentrator and set the flow meter to your prescribed rate.
- Look for a steady stream of bubbles coming from the tubing. Consistent bubbling indicates that oxygen is flowing correctly. If there are no bubbles or the bubbling is inconsistent, there may be a blockage or a leak in your tubing or system.
Monitoring Your Body’s Response
Beyond the machine itself, your body provides the most direct feedback on the effectiveness of your oxygen therapy. While device indicators are important, your physical symptoms are the ultimate gauge of success.
Signs of Effective Oxygen Therapy
- Reduced Shortness of Breath: You should feel less winded and find it easier to breathe during daily activities.
- Increased Energy: Fatigue is a common symptom of low oxygen levels. Effective therapy often leads to higher energy levels and a greater ability to participate in activities.
- Improved Sleep: Oxygen therapy can promote better sleep quality by preventing oxygen levels from dropping during the night.
- Reduced Headaches and Irritability: Lowered oxygen can cause headaches and mental fogginess. As your levels improve, these symptoms should subside.
Using a Pulse Oximeter for Verification
A pulse oximeter is a small, painless device that clips onto your fingertip to measure your blood oxygen saturation level (SpO2). It is a vital tool for confirming your therapy is working.
- Before Use: Ensure your hands are warm and you do not have nail polish or artificial nails on the finger you will use, as these can interfere with the reading. Sit still and rest for a few minutes before taking a measurement.
- Normal Range: For most healthy individuals, a reading between 95% and 100% is considered normal. If you have a chronic respiratory condition, your doctor may have given you a different target range. Compare your readings against this personalized target.
- Accuracy: Note that over-the-counter oximeters can have a margin of error. Always follow your doctor's guidance regarding your specific target range and what to do if readings are consistently low.
Comparison of Normal vs. Problematic Indicators
| Feature | Working Oxygen Concentrator | Potential Problem | Action to Take |
|---|---|---|---|
| Visual | Steady green light, clear display | Flashing yellow/red light, alarm | Follow troubleshooting steps or call provider |
| Auditory | Consistent, low humming, faint hiss | Rattling, banging, loud beeping | Isolate and fix the issue, or get professional help |
| Flow | Steady stream of bubbles in water | No bubbles or intermittent flow | Check tubing for kinks, leaks, or blockages |
| Body Symptoms | Improved breathing, more energy | Increased shortness of breath, fatigue | Consult your doctor, use backup oxygen |
| Pulse Oximeter | Stable reading within target range | Consistently low or fluctuating readings | Re-test and consult your healthcare provider |
Troubleshooting Common Issues
If you suspect your oxygen is not working correctly, you can perform a few simple troubleshooting steps before contacting your provider.
- Check Power: Ensure the unit is securely plugged into a working power outlet. For portable units, check that the battery is charged and properly seated.
- Inspect Tubing: Look for any kinks, twists, or blockages in the nasal cannula or oxygen tubing. A pinched tube can completely cut off oxygen flow.
- Clean Filters: Many concentrators have a gross particle filter that needs to be cleaned regularly to prevent airflow obstruction. Always follow the manufacturer's instructions for filter maintenance.
- Allow Warm-Up Time: When you first turn on the machine, it needs a few minutes to build up to the correct oxygen concentration. Wait for 5-10 minutes before checking for a low-purity alarm.
When to Contact Your Healthcare Provider
While basic troubleshooting can solve many issues, some problems require professional attention. You should contact your doctor or oxygen provider if:
- Your low-purity alarm persists after cleaning the filters and checking the tubing.
- You consistently receive low pulse oximeter readings, even when using your oxygen.
- You experience increasing shortness of breath, fatigue, or other symptoms of low oxygen.
- Your machine makes unusual noises that suggest a mechanical failure.
- You need to use your backup oxygen supply frequently due to concentrator failure.
By being proactive and aware of both your machine's performance and your body's response, you can ensure your therapy remains effective.

Conclusion
Confirming the effectiveness of your oxygen therapy involves a combination of observing your equipment and listening to your body. Regular checks of visual indicators, auditory signals, and oxygen flow are crucial. Additionally, monitoring your physical symptoms and using a pulse oximeter provides an important layer of verification. By staying vigilant and taking action when something seems wrong, you can ensure your oxygen therapy is working properly and providing the health benefits you depend on.
