2 A portable oxygen machine can help you stay active by providing safe, effective delivery of oxygen while you’re out and about.īut finding the best portable oxygen concentrator for your needs can be confusing-especially if you’re buying one for the first time. 1 Also, a 2021 study of more than 32,000 adults with chronic obstructive pulmonary disease (COPD) or certain types of lung diseases found that those who were physically active had longer lifespans and improved heart rates. Research published in the Journals of Gerontology shows older adults who are socially active have better physical health and emotional well-being. It’s important to stay active even if you need extra oxygen. If you’ve been prescribed supplemental oxygen by your doctor, using a portable oxygen concentrator, also called a portable oxygen machine, can be a convenient way to meet your oxygen needs while still getting out and doing all the things you enjoy.
