Frequently Asked Questions

11. When is oxygen therapy used for COPD?

For people with severe COPD and low levels of oxygen in the blood, doctors may recommend oxygen therapy to help with shortness of breath. Using extra oxygen more than 15 hours per day can help you perform tasks or activities with less shortness of breath, protect the heart and other organs from damage, help you sleep more, improve your alertness during the day, and help you live longer.
