Oxygen is what enables every cell in the human body to create energy. Whether it's hiking, walking or just talking, all life depends on breathing oxygen. 

While many find breathing an easy task, a growing number of people with COPD and other respiratory conditions do not. That's why ResMed is developing new solutions to improve respiratory care. 

ResMed Mobi, our portable oxygen concentrator, features a balance of oxygen, weight and battery life so you can help your patients do more.
