Why You Might Need Oxygen Therapy
Understanding why oxygen therapy is necessary is the first step to embracing it. Here’s what happens inside your body when COPD limits oxygen flow—and how supplemental oxygen can help.
Oxygen is the fuel your organs and muscles need to function. As COPD progresses, the lungs struggle to absorb and deliver enough oxygen, and symptoms can worsen.
Common signs of low oxygen in the blood include:
- Fatigue, especially during activity
- Trouble concentrating or memory lapses
- Swelling in the legs
- Blue lips or fingertips
- Increased risk of heart issues
If your doctor diagnoses chronic respiratory failure, it means your blood oxygen levels remain low—sometimes with a buildup of carbon dioxide. In this case, oxygen therapy may be prescribed to help your organs function properly.
Benefits of Long-Term Oxygen Therapy
Beyond helping you breathe, long-term oxygen therapy offers several life-enhancing benefits. Let’s break down what it can do for your health and daily life.
- ✅ Prolongs life (even though it doesn’t cure lung function)
- ✅ Reduces fatigue and shortness of breath
- ✅ Improves sleep quality and mental clarity
- ✅ Enhances quality of life and physical ability
- ✅ May support heart function
To work effectively, oxygen therapy must be used for at least 15 hours per day. It’s not addictive, but consistency is key.
Understanding Your Oxygen Prescription
Your oxygen therapy plan is tailored just for you. Here’s what to expect from your prescription and why following it exactly is so important.
Your oxygen prescription is as personal as any medication. It will include:
- Flow rate in litres/minute (resting, exertion, sleep)
- Duration (number of hours per day)
Always follow your prescribed flow rate. Never change it on your own—extra oxygen may cause harm. And yes, oxygen during naps counts too!
It might take time to feel the effects. Stay consistent and speak with your care team if you don’t notice immediate changes.
Your Oxygen Equipment: What You Need to Know
Not all oxygen systems are the same. Get to know the types of equipment available so you can use the one that fits your lifestyle best.
Oxygen can be delivered in three main ways:
- Concentrators
- Cylinders
- Liquid Oxygen Tanks
1. Concentrators
Concentrators are one of the most common oxygen delivery methods. Here’s how they work and how to use them safely.
Pull oxygen from the air—economical and ideal for home use.
Can be fixed (plugged in) or portable (battery-powered).
🔌 Always follow usage and safety guidelines, and don’t obstruct filters.
2. Cylinders
Cylinders are a portable option that allow more freedom for outings. Here’s how they’re used and why they’re helpful as a backup.
Compressed gas tanks—great for backup or going out.
Often paired with oxygen-saving valves to extend usage time.
✅ Check the flow control each time and avoid leaks or overheating.
3. Liquid Oxygen Tanks
Liquid oxygen packs a lot of power into a small space. Learn how it works, what to watch for, and how to refill it properly.
Store a large amount of oxygen in a small space.
Come with a big tank for home and a small portable tank for outings.
❄️ Liquid oxygen is cold!
Accessories
A good setup goes beyond just tanks and machines. These essential accessories help you stay mobile, comfortable, and safe.
- Nasal cannula: Delivers oxygen directly to your nose
- Connector tubing: Allows mobility inside the home
💡 Replace your cannula every 3–4 weeks and avoid using oil-based products near oxygen.
Safety First: Oxygen and Fire Hazards
Oxygen therapy is safe when used correctly—but it must be handled with care. Here are vital safety rules to keep you and others protected.
Oxygen doesn’t explode, but it intensifies fire. Follow these rules:
- Never smoke—or allow smoking—near oxygen
- Keep oxygen at least 3 meters from heat sources
- Avoid using oil-based creams, sprays, or flammable products
- Never try to fix your own equipment
If your nose is dry, use water-based lubricants only. Always clean your equipment regularly.

Living Fully with Oxygen at Home
Oxygen isn’t a limitation—it’s a tool for empowerment. With the right approach, you can still enjoy daily routines and physical activity.
Oxygen therapy isn’t about staying still—it’s about doing more with confidence.
You can (and should) use oxygen for:
- Exercise and physical activity
- Daily tasks like dressing, showering, or cooking
- Sleep (if prescribed)
- Sexual activity
- Flare-ups (24/7 use is often needed)
Oxygen helps reduce fatigue, improve endurance, and lets you enjoy your day-to-day life with fewer limitations.
Sleeping with Oxygen
Oxygen needs don’t disappear at night. Discover how nighttime oxygen therapy can help you rest better and stay healthier.
During sleep, your breathing slows—and so does your oxygen intake.
Oxygen at night can help:
- Improve sleep quality
- Prevent nighttime desaturation
- Avoid complications from low oxygen levels
Not all provinces prescribe oxygen only for sleep. If you have concerns, ask for a sleep study to check for conditions like sleep apnea.
Traveling with Oxygen: Yes, You Can!
Don’t let oxygen therapy stop you from seeing the world. With the right planning, travel is not only possible—it can be enjoyable.
Traveling with oxygen is possible—you just need to plan ahead.
How to travel with oxygen: practical tips
- Let your oxygen provider know at least 1 month in advance
- Arrive at destinations on weekdays when possible
- Contact airlines, trains, or cruises ahead of time
- Use FAA-approved portable concentrators if flying
- Carry prescriptions and a medical letter if needed
🛫 Oxygen during flights is essential—altitude lowers oxygen in the air.
Using Oxygen During Flare-Ups
When symptoms worsen, your oxygen needs change. Here’s what to do during a COPD exacerbation to stay safe and supported.
When your symptoms worsen, your oxygen needs increase. Use your oxygen more often—ideally 24/7—and only adjust flow rates if your doctor tells you to.
Call your doctor or go to the ER immediately if you experience any of the following warning signs
- Headaches
- Confusion or agitation
- Blue fingers or lips
- Severe fatigue
Adjusting Emotionally to Oxygen Therapy
Oxygen can change how you see yourself—but it doesn’t define you. Here’s how to cope with emotional reactions and reclaim your sense of self.
It’s completely normal to feel:
- Embarrassed or self-conscious in public
- Worried about your identity or independence
- Frustrated by equipment noise or limitations
These feelings are valid. Talk about them. Share with your care team or loved ones. You are not alone, and oxygen doesn’t define who you are—it supports the life you want to live.
Talking to Friends & Family
Oxygen therapy can raise questions—not just for you, but for your loved ones. Here’s how to start the conversation and offer reassurance.
When you start oxygen therapy, loved ones may be unsure of how to respond.
Reassure them that:
- Oxygen therapy extends your life, it doesn’t mean you’re dying
- You can still live well and do things you enjoy
- It’s a medical tool—not a limitation
Invite them to ask questions and express their concerns openly.
David’s Story: Breathing with Strength
Sometimes the most powerful lessons come from others who’ve walked the path. David’s story shows what’s possible when oxygen becomes an ally, not an obstacle.
“At first, I saw oxygen as a burden. Now I see it as support.”
David’s journey with supplemental oxygen began after years of denying his COPD diagnosis. He feared the equipment, the stigma, and the loss of independence. But today, he uses oxygen to stay active, attend church, and enjoy life at his own rhythm.
Like many, David’s greatest challenge was mental. Once he overcame the fear, he realized oxygen wasn’t holding him back—it was pushing him forward.
Frequently Asked Questions (FAQ) About Oxygen Therapy and COPD
How many hours a day should I use my oxygen?
Most people need to use oxygen for at least 15 hours per day to experience the full benefits. In cases of severe COPD or during flare-ups, 24/7 use may be recommended. Always follow your doctor’s prescription.
Can I go out in public while wearing oxygen?
Yes, absolutely. Portable oxygen systems are designed for mobility. You can go shopping, take walks, attend social events, and more. Many people worry about the stigma, but remember: using oxygen shows strength and commitment to your health.
Is it dangerous to use oxygen at home?
Oxygen therapy is safe when used properly. However, oxygen fuels fire, so it’s important to:
- Never smoke near your equipment
- Keep it away from heat sources and flammable products
- Follow all safety instructions from your provider
Can I travel with oxygen therapy?
Yes! You can travel by car, train, boat, and even plane—with the right planning. Talk to your oxygen provider at least one month before your trip, and make arrangements with airlines or cruise companies. Use FAA-approved portable concentrators for air travel.
Will oxygen therapy make me dependent or worsen my lungs?
No. Oxygen is not addictive and won’t weaken your lungs. It simply helps your body get the oxygen it needs. Stopping therapy suddenly or not using it as prescribed can be harmful.
What if I feel self-conscious about wearing oxygen in public?
It’s natural to feel that way at first, but many people find that using oxygen gives them the confidence to go out and enjoy life again. Remind yourself: you’re not defined by the tube—you’re defined by your determination to stay active and well.
Can I sleep with oxygen? Will it bother me?
Yes, and in fact, many people need oxygen at night because breathing naturally slows during sleep. If you’re uncomfortable with the nasal cannula, ask about different models or comfort adapters.
How do I know if my oxygen level is too low?
Your doctor may use a pulse oximeter to measure your oxygen saturation (SpO2). If it falls below 90%, oxygen therapy may be required. For more accurate assessment, an arterial blood gas test can be performed.
Final Tips for Confidence
Ask yourself:
- Do I feel ready to use my oxygen as prescribed?
- Can I manage my equipment confidently?
- Am I prepared to travel or sleep with oxygen?
- Do I believe oxygen will improve my quality of life?
If you answered “not yet,” talk to your healthcare provider. Build a plan that makes you feel empowered, not restricted.
Conclusion: Oxygen is Freedom, Not Limitation
Long-term oxygen therapy isn’t the end of independence—it’s the beginning of taking back control. With the right tools, planning, and mindset, you can breathe easier, move freely, and live fully.
