Oxygen therapy can be life-changing for people with chronic lung conditions like Chronic Obstructive Pulmonary Disease (COPD), pulmonary fibrosis, or heart failure. When used properly, supplemental oxygen helps you breathe easier, sleep better, and stay active. But using oxygen the wrong way can lead to serious health and safety risks, some of which are easily overlooked.
At Doubek Medical Supply, we want to help you stay safe and get the most out of your oxygen therapy. Here are seven common oxygen therapy mistakes and how to avoid them.
1. Using the Wrong Oxygen Device for Your Needs
Not all oxygen systems are the same. There are oxygen concentrators, portable oxygen tanks, and liquid oxygen systems, each with different benefits. Choosing the wrong setup can make daily life harder or limit your mobility.
Talk with your doctor and a qualified medical equipment provider (like Doubek) to find the device that fits your lifestyle and prescription needs.
2. Changing Your Flow Rate Without Medical Advice
It might seem harmless to adjust your flow rate if you’re feeling short of breath, or to turn it down to make your supply last longer, but changing your oxygen settings without a doctor’s approval can be dangerous.
Too much oxygen can lead to oxygen toxicity, and too little can result in low oxygen levels (hypoxia).
Note: Always use the flow rate prescribed by your doctor, and never adjust it without medical supervision.
3. Smoking Near Your Oxygen Equipment
Oxygen is not flammable, but it feeds fire. Even a small flame near oxygen equipment can lead to a fast-spreading fire or explosion. Smoking is one of the top causes of oxygen-related house fires.
Tip: Never smoke, or allow others to smoke, anywhere near your oxygen setup. Post “No Smoking” signs at home and educate everyone around you.
4. Using Petroleum-Based Products
Lotions or creams that contain petroleum (like Vaseline) can ignite in the presence of oxygen, especially around the face where nasal cannulas sit.
Tip: Stick to water-based products for skincare, lip balm, or nasal dryness. Also avoid aerosol sprays, which can be flammable.
5. Skipping Equipment Cleaning and Maintenance
Bacteria can build up on oxygen tubing, nasal cannulas, and concentrator filters. If left uncleaned, it can lead to infections, especially for people with compromised lung function.
Cleaning Tips:
- Clean your nasal cannula and tubing weekly using a mild soap or vinegar-water solution.
- Replace them as recommended (usually every 2–4 weeks).
- Wipe down your concentrator daily with a gentle, non-toxic cleaner.
- Follow all maintenance guidelines provided with your device.
6. Storing Oxygen Tanks Unsafely
Oxygen tanks should always be kept upright, in a well-ventilated space, and away from heat sources like radiators, stoves, or direct sunlight. Storing them improperly can lead to leaks or, in rare cases, explosions.
Tips for Proper Use:
- Use an approved tank stand or cart to secure your tanks.
- Never cover oxygen equipment with fabric, towels, or blankets.
- Keep tanks at least 5–10 feet away from open flames or heat.
7. Not Having a Backup Plan for Power Outages
If you rely on a home oxygen concentrator, a power outage can quickly become a medical emergency. Many people don’t think about a backup plan until it’s too late.
Power Tips:
- Keep a fully charged portable oxygen tank on hand as a backup.
- Notify your local utility company that you use oxygen, as they may prioritize power restoration for medical needs.
- Consider a battery backup unit or generator if power loss is a frequent concern.
Stay Safe, Breathe Easy
Oxygen therapy can help you live a fuller, more active life, but only if you use it safely. By avoiding these common mistakes, you can protect your health, reduce fire risks, and prevent serious complications.
