What is oxygen
Oxygen is a natural part of the air we breathe, but it makes up less than a quarter of the gases we call air. Our bloodstream collects oxygen from our lungs and transports it to the tissues of our body. The cells within these tissues use both oxygen and the food we eat to create energy.
Why do I need oxygen
If you have chronic lung disease, some areas in your lungs are damaged. These damaged areas act as blockages, preventing oxygen from moving into your bloodstream. You are unable to capture enough oxygen during a breath for your body to thrive. You likely experience difficulties breathing, sleeping and performing daily activities.
Medical oxygen increases the amount of oxygen available to your bloodstream in each breath. The increased oxygen concentration eases the capture of enough oxygen by your bloodstream to supply your body. This helps you breathe more comfortably, so you can enjoy your daily activities.
Can I ever stop using oxygen
Unfortunately, if your lung disease has caused enough lung damage to force the need for oxygen, you will likely need it for the rest of your life. However, some lung conditions are treatable with the use of medications or by curing an infection; in those cases, patients may overcome the need for oxygen.
