How to Troubleshoot Common Problems with Oxygen Concentrators

Oxygen concentrators are essential for home therapy but can encounter issues that disrupt their performance. For low oxygen flow, check for kinks in the tubing, clean the cannula, and confirm device settings. To prevent overheating, check if for proper ventilation, clean filters, and avoid direct sunlight. For power issues, check the power cord to be sure it's plugged in, and consider a backup battery or generator. If alarms go off, refer to the manual, check for blockages, and contact support if needed. To stay active, use a rolling cart, choose a portable model, or designate storage areas. To reduce noise, place the device on a flat surface and clean the compressor intake. Avoid tangled tubing by using shorter or tangle-free tubing. For dry nasal passages, use a humidifier bottle or saline spray. Keep oxygen concentration steady by scheduling regular maintenance and replacing filters and sieve beds. If the device stops unexpectedly, reset it, check the circuit breaker, and contact support if needed.

Oxygen concentrators play a significant role in offering continuous, reliable oxygen therapy for individuals with respiratory conditions. However, even the most dependable machines can have problems that disrupt therapy. Addressing these common concentrator issues is important to keep therapy running smoothly. Read on as we explore 10 common problems with oxygen concentrators and offer practical solutions to troubleshoot and fix them.

Overheating is a sign that parts of your concentrator are likely malfunctioning. This can reduce the performance and lifespan of your oxygen concentrator. Here's how to address the issue and cooling tips to prevent future occurrences:

Solution:

• Promote proper device ventilation: Place the device in an open, well-ventilated area to reduce the chances of overheating.² Avoid placing the concentrator against walls, furniture, or curtains, which could block vents and reduce airflow.
• Clean the filters: Dust or debris in the filters can restrict airflow, making the device work harder to circulate air and causing it to overheat. Remove and clean the oxygen filters according to the manufacturer’s instructions and make sure the filters are dry before reinserting.
• Avoid Heat Exposure: Avoid direct sunlight by placing the device in a cool, shaded spot away from windows, using curtains or blinds if needed. Keep the concentrator in a controlled environment, avoiding high temperatures that could harm the device.³

When alarms start going off frequently from your oxygen concentrator, this can indicate several issues that need attention. Understanding what the oxygen concentrator alarm codes mean and how to address persistent device warnings is important.

Solution:

• Recognizing alarms: Check the manual to identify alarms or error codes and understand their specific sounds or patterns. Addressing alarms promptly ensures your concentrator works properly and supports effective therapy.
• Common warnings: User manual troubleshooting helps determine traditional problems that may be happening with your machine. Alarms often signal system blockages, low oxygen levels, power supply issues,⁵ or environmental triggers. Understanding common system alarms enables efficient troubleshooting during a malfunction.
• Contact support if needed: If an alarm continues, despite troubleshooting with the manual, contact your concentrator supplier or a qualified technician for assistance.

Oxygen concentrators can be heavy or awkward to move, creating challenges for daily use. Here are some solutions to ease mobility challenges and storage issues.

Solution:

• Use a rolling cart: Invest in a sturdy, wheeled cart with secure straps or compartments to stabilize the concentrator. Look for an oxygen cart that is easy to maneuver and works on various surfaces or ramps.
• Consider a portable model: Choose a lightweight portable oxygen concentrator for easy transport. These models often include carrying cases, built-in wheels,⁶ and battery power for added flexibility during travel.
• Plan designated storage areas: Store the concentrator near power outlets to reduce the need for frequent repositioning. Keep tubing and accessories near the device to minimize handling.

Excessive noise from the oxygen concentrator can be distracting and indicate underlying issues. By paying attention to unusual sounds, you can detect issues and determine if the concentrator is not operating at its optimal level.

Solution:

• Operate on a flat surface: Make sure the concentrator is placed on a solid, level surface. This minimizes vibrations that can contribute to noise. The concentrator should not be placed near walls or other objects that can cause vibrations or rattling sounds. Doing this also keeps the device from overheating.
• Clean the compressor intake: Dust and debris can increase noise levels in the machine. Clean the intake vent regularly with a soft cloth or brush to remove dirt or blockages for compressor noise reduction.
• Check for loose parts: Make sure all screws and components are tightly secured to avoid unnecessary, oscillating sounds.

Dry or irritated nasal passages can be a common problem for oxygen users. Tips to provide comfort during oxygen therapy and offer nasal irritation relief include:

Solution:

• Try a humidifier bottle attachment: Connect an oxygen humidifier to your oxygen concentrator to add moisture⁸ to the oxygen before it reaches your nasal passages. Fill it with clean, distilled water and check the water level regularly.
• Consider a saline nasal spray: Nasal saline spray relieves dryness and helps moisturize nasal passages. Using a spray specifically designed for the nose helps avoid irritation from extended oxygen use.
• Stay hydrated: Drink plenty of water throughout the day to keep your body hydrated. Proper hydration prevents nasal dryness and irritation caused by the dry air from the oxygen concentrator.

After extended use, your device may deliver less oxygen than expected. Here's what to do to maintain your oxygen concentrator efficiency over time.

Solution:

• Schedule regular maintenance: Follow the manufacturer’s recommended maintenance guidelines to keep your concentrator running efficiently. This helps the device perform optimally, identifying early issues before they affect oxygen concentration.
• Replace filters and sieve beds: Filters capture dust and debris that can block airflow and sieve beds help separate nitrogen from oxygen. With frequent use, components become less effective and can lead to declining oxygen output. Follow the user manual for sieve bed maintenance and a filter replacement schedule, using manufacturer-approved parts to maintain performance.

If your oxygen concentrator stops working suddenly, it can disrupt therapy. Identify and address unexpected stoppages with these emergency troubleshooting tips.

Solution:

• Perform a basic device reset: Power off the device, wait a few minutes, and turn it back on to clear minor errors or glitches. Refer to the user manual for reset instructions, as some models include a dedicated reset button or function in the settings.
• Check the circuit breaker: Problems with the power supply can cause the device to stop, so verify that the machine is plugged into a working outlet. Circuit breaker checks verify the outlet isn't overloaded or tripped. If it is tripped, reset it and try turning the device on again.
• Check for error codes or warning lights: As mentioned above, concentrators display error codes or warning lights when something is wrong. Consult the user manual to interpret these codes and contact the manufacturer for repair services.
