Increases Survival

Supplemental oxygen, worn at least 15 hours a day, increases survival in some patients. And today’s portable oxygen technology allows you to utilize portable oxygen therapy 24 hours a day, 7 days a week, anytime, anywhere.

Improves Exercise Tolerance

Studies show that using supplemental oxygen during exercise allows you to exercise longer, at a higher intensity, which means you’ll reap greater rewards for all your efforts.

Improves Mental Alertness

Are you in a mental fog? When you’re not getting enough oxygen, every organ of your body is affected, including your brain. Confusion is the first sign that people with lung disease may not be getting enough oxygen. Using supplemental oxygen keeps your brain, and all your other vital organs, healthy.
