Taking a cruise anywhere was one of the last things on my mind when I was diagnosed with COPD and had to go on oxygen therapy. I thought my days of doing anything fun and adventurous like that were over. I didn't really understand back then that it didn't have to be that way!
I didn't know anything about portable oxygen concentrators when I first started taking oxygen therapy to treat my emphysema. I just resigned myself to using tanks and having oxygen delivered to my house. I got tired of that after about the first 6 months of using it. I was also starting to feel really cooped up. I didn't like taking my tank with me anywhere, let alone consider going on vacation.
