Oxygen therapy is one of the leading treatment options for lung disease such as COPD, emphysema, chronic bronchitis as well as lung cancer.
Oxygen therapy can be delivered through the standard cumbersome oxygen tank, liquid oxygen, or through a portable or home oxygen concentrator.
All three options are viable but only one option will allow you to travel and move around with ease.
Portable oxygen concentrators are FAA approved to be used during air travel and no other oxygen delivery system is as light-weight and mobile as a portable oxygen concentrator.
